HT82K28A - Win98 Keyboard Encoder

Datasheet Summary

Description

The HT82K28A is a keyboard encoder especially designed for IBM PC/AT, IBM PS/2 and all compatible machines.

The HT82K28A accepts keyboard inputs and contains a 16-character first-in-first-out buffer in which data is stored.

An inexpensive RC oscillator can be used for the system clock.
