DP8212/DP8212M 8-Bit Input/Output Port

General Description

Features

8-Bit data latch and buffer

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.

Service request flip-flop for generation and control of

interrupts

0.25 mA input load current

TRI-STATE TTL output drive capability

Outputs sink 15 mA

Asynchronous latch clear

3.65V output for direct interface to INS8080A

Reduces system package count by replacing buffers,

latches, and multiplexers in microcomputer systems

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.
