Keyboard (R1, R2, R3, R4, C1, C2, C3, C4)
These inputs can be interfaced to an XY matrix keyboard.
C1-C4 & R1-R4 are set to low at On Hook (HS = high). C1-C4 key inputs are set
to low and R1-R4 are set to high at OFF HOOK (HS = low) which enables the key-
input operation. The oscillator starts running when a keypress is detected. Scanning
signals are presented at both column and row inputs (TYP : 437Hz) until the
input key is released. Key inputs are compatible with standard 2-of-8 form or
single-contact keyboard. Debouncing is provided to avoid false entry (TYP : 4mS).
Hook Switch
This input detects the state of the hook switch contack. “Off Hook”
corresponds to V
SS
condition. “On Hook” corresponds to V
DD
condition.
Make/Break Ratio
This input provides the selection of the Make/Break ratio (33.3: 66.6/40:60)
when M/B is connected to V

Oscillator Input/Output
These pins are provided to connect an external 3.58MHz crystal. Oscillator
starts (at Off Hook) and is sustained unitl pulse or DTMF signals are finished.
Power
These are the power supply inputs. The device is designed to be operated on
2.0V to 5.5V
DTMF Signal Output
When a valid keypress is detected in DTMF mode, appropriate low and high
group frequencies are generated which hybrid the Dual Tone Output.
Tone out is Off State in pulse mode.

DP : The normal output will be “ON” during break and “OFF” during make at
“OFF HOOK”. The output will be “OFF” at “ON HOOK”.
