DP8212 DP8212M 8-Bit Input Output Port
General Description
The DP8212 DP8212M is an 8-bit input output port con-
tained in a standard 24-pin dual-in-line package The device
which is fabricated using Schottky Bipolar technology is
part of National Semiconductor’s 8080A support family The
DP8212 DP8212M can be used to implement latches gat-
ed buffers or multiplexers Thus all of the major peripheral
and input output functions of a microcomputer system can
be implemented with this device
The DP8212 DP8212M includes an 8-bit latch with
TRI-STATE output buffers and device selection and con-
trol logic Also included is a service request flip-flop for the
generation and control of interrupts to the microprocessor
