DP8212/DP8212M 8-Bit Input/Output Port
General Description
The DP8212/DP8212Misan 8-bit input/output port con-
tainedina standard 24-pin dual-in-linepackage.Thedevice,
whichis fabricated using Schottky Bipolar technology,is
partof National Semiconductor’s 8080A support family.The
DP8212/DP8212Mcanbe usedto implement latches,gat- buffers,or multiplexers. Thus,allofthe major peripheral
and input/output functionsofa microcomputer systemcan implemented withthis device.
The DP8212/DP8212M includes an 8-bit latch with
TRI-STATEÉ output buffers,and device selectionand con-
trol logic. Also includedisa service request flip-flopforthe
generationand controlof interruptstothe microprocessor.
Features 8-Bit data latch and buffer Service request flip-flopfor generation and controlof
