General Description

The HT6513 is a specially designed CMOS IC

for mouse control applications. Capable of driv-

ing up to 3 key-switches and 4 photo-couplers

directly into a standard RS-232C line, and it

can be operated without an external power sup-

ply. It is compatible with both Microsoft and

Mouse systems with false entries being pre-

vented by internal debounce circuits.
