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
