Description

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
