MSM82C43, INPUT/OUTPUT PORT EXPANDER

The MSM82C43 is an input/output port expander device based on CMOS technology and designed to operate at low power consumption levels.

In systems employing the MSM80C48/49 8 *bit single chip microcomputers, 4 *bit data can be expanded by dividing between four I/O lines by executing the
