Chip enable, active low.

The system oscillator consists of an inverter, a bias resistor, and the

required load capacitor on chip. The oscillator function can be

implemented by Connect a standard 3.579545MHz crystal to the X1 and

X2 terminals.

Negative power supply.

No connection.

Data inputs for the parallel mode.

When the IC is operating in the serial mode, the data input terminals

(D0~D3) are included with a pull-high resistor. When the IC is operating

in the parallel mode, these pins become floating.

Operation mode selection input

S/P =”H”: Parallel mode

S/P =”L”: Serial mode

Data synchronous clock input for the serial mode. When the IC is

operating in the parallel mode, the input terminal (CLK) is included with

a pull-high resistor. When the IC is operating in the serial mode, this pin

becomes floating.

Data input terminal for the serial mode. When the IC is operating in the

parallel mode, the input terminal (DATA) is included with a pull-high

resistor. When the IC is operating in the serial mode, this pin becomes

floating.

Output terminal of the DTMF signal.

Positive power supply, 2.0V~5.5V for normal operation.
