Counterfeit electronic parts are so difficult to detect that more than a million suspect counterfeit parts slipped past highly trained military inspectors and made their way into the defense supply chain. Watch it! Why counterfeits come from China. Buyers leave positive feedback when parts look good and arrive on time and counterfeits often look better than authentic parts.

For RS it is 50 feet 15 meters , or the cable length equal to a capacitance of pF, at a maximum transmission rate of When we reduce the baud rate, it allows for longer cable length.

For Example:. Fail Safe is an attempt to keep the output of the RS receiver to a known state. Standard fail safe supports open inputs while enhanced fail safe transceivers such as the SP and XR support open input, shorted input and undriven terminated lines without external biasing. In this example, we looked for XRA Click on part number header or on the link at the bottom of the result.

This brings you to the product page. For example:. The screen changes to:. A legend tells you the definition of the different statuses. Type the part into the search, and click on one of the part numbers from the drop down menu. Then you can look for the Product Discontinuation Notice, which generally is at the top of the list, for example:. If you see this, it tells you that this particular orderable part has been discontinued and when the last order date is, or was.

If you click on the file, then you can view the notice we sent about this if you purchased the part in the recent past. It may also advise of a replacement part. When an orderable part first becomes discontinued, Product Discontinuation Notices are sent are sent to those who have purchased the parts in the recent past, if purchased directly, with a dated opportunity to place a last order.

Cross Reference Search. The RS protocol allows up to 10 receivers to be connected to a multipoint bus transmission line. The SP26LV features a receiver enable control common to all four receivers and a high-Z output with 6mA source and sink capability.

Design Tools. EOL End of Life - the part is no longer being manufactured, there may or may not be inventory still in stock. CF Contact Factory - the part is still active but customers should check with the factory for availability. Longer lead-times may apply. PRE Pre-introduction - the part has not been introduced or the part number is an early version available for sample only. OBS Obsolete - the part is no longer being manufactured and may not be ordered.

Frequently Asked Questions Search. A cable length of 15 meters 50 feet will do a maximum of 10Mbps. Also, RS allows for multi-point operation, up to 32 unit loads. Transceivers may use a fraction of a unit load, increasing the number of devices on the bus. Therefore, XR allows more than devices 32 x 10 on the bus. Assuming you short only one pin of an SP26LV differential pair output to Ground, can you do it indefinitely?

The problem is when the driver outputs a signal, the grounded output sees the short to ground and tries to drive this low impedance. The driver will go into current limiting mode. The output can be shorted indefinitely due to this protection. The other output will most likely react in an erratic fashion. Our source must be AC-coupled, and then terminated into 75 ohms at the receiver.

What do you recommend? This part is used in a RS system and its inputs are connected to a single RS driver with differential outputs. These receivers are not used as a single ended input. The receiver input has a sensitivity of mV at A and B inputs. Perhaps a single ended protocol such as RS would be more suitable for your application. Yes, this is possible using one RS transceiver. The microcontrollers will have to be addressable and have tri-state outputs. The micros will have to be in either receiving mode or tri-state mode when the RS transceiver is transmitting data.

When the host transmits it will have to send an address to the specific micro. If any micro transmits the transceiver will have to be in receiving mode and all other micros will have to be in receive or tri-state.

So the host would have to initiate this sequence by addressing the micro first then switch the transceiver to receive. The half duplex system would have a bus with one transceiver and multiple microcontrollers all tied to the bus. For 5V systems the SP family can be used. For 3V systems the SP family can be used. The require speed will determine the part number. The SP part runs up to speeds of 16Mbps. Care must be taken to assure the transceiver can drive the multiple micros in RX mode.

How much ESD voltage could a part see in normal use? ESD is caused by static electricity. In order for an ESD event to occur there must be a buildup of static charge.

Very high charge levels are actually quite rare. In a normal factory environment, taking basic ESD precautions grounding-straps, anti-static smocks, ionizers, humidity control, etc.

In an uncontrolled environment, like an office, static levels rarely get above volts. Under some worstcase conditions wearing synthetic fabrics, rubbing against synthetic upholstered furniture, extremely low humidity. All ICs, even those with robust protection, can be damaged if they are hit hard enough or often enough. Why are some pins protected to higher ESD levels than others? After the system is put together they are soldered onto the PCB and shielded within a metal or plastic system enclosure.

Interface ICs are designed to attach to an external connector that could be exposed to ESD when a cable is plugged in or when a person or object touches the connector. These interface pins are most likely to see ESD exposure and therefore benefit from additional protection. Others do not. What does the E mean? Most of our interface devices are available in different temperature grades.

The best way to determine this is to go to maxlinear. At or near the top of the results you should see something that looks like:. And then Product Change Notifications:. Purchase Parts.
