______

PULSE

number sequence stored on-chip will be outpulsed. Any other valid key entries

will clear the memory and outpulse the new number sequence.

18 Pulse Output

The Pulse output is an open drain N-channel transistor designed to drive external

bipolar transistor. These transistor would normally be used to pulse the telephone

line by disconnecting and connecting the network. The IL5851N pulse output is

an open circuit during make and pulls to the GND supply during break.

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this

high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or

VOUT)≤VCC.

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused

outputs must be left open.
