Manual zz. X Y Pad No. X Y 1 The oscillator function can be implemented by Connect a standard 3. When the IC is operating in the parallel mode, these pins become floating. When the IC is operating in the serial mode, this pin becomes floating. CLK Rev. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.
The relationship between the digital codes and the tone output frequency is shown in Table 1. As for the control timing diagram, refer to Figure 1. Every digit of a phone number to be transmitted is selected by a series of inputs which consist of 5-bit data. Table 1: Digits vs. The relationship between the digital codes and the tone output frequency is illustrated in Table 2.
As for the control timing diagram, see Figure 2. Then the input data codes should be determined. Thus, these data input pins should not float.
