I/O FUNCTION
I The keyboard input is compatible with a standard 5 x 6
keyboard, an inexpensive single contact (Form A)
keyboard, and electronic input.
In normal operation, any single button can be pushed to
produce dual tone, pulses, or function. Activation of two
or more buttons will result in no response except for
single tone.
I A built-in inverter provides oscillation with an
inexpensive 3.579545 MHz crystal. The oscillator
ceases when a keypad input is not sensed. The crystal
frequency deviation is 0.02%.
O Crystal oscillator output pin.
O The T/P MUTE is a conventional CMOS N-channel
open drain output.
The output transistor is switched on low level during
dialing sequence (both pulse and tone mode).
Otherwise, it is switched off.
