Description

CMOS IN Pull-high

Chip enable, active low

2X2

3X1

Oscillator

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.

4VSS

Negative power supply.

No connection.

6~9

D0~D

CMOS IN Pull-high

or floating

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.

ICMOS IN

Operation mode selection input

=”H”: Parallel mode

=”L”: Serial mode

CLK

CMOS IN Pull-high

or floating

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

CMOS IN Pull-high

or 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.

DTMF

CMOS OUT

Output terminal of the DTMF signal

VDD

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