8212 8-Bit Input/Output Port DIP-24

The 8212 I/O port consists of an 8-bit latch with 3-state output buffers along with control and device selection logic. Also included is a service request flip-flop for the generation and control of interrupts to the microprocessor.

Features

• Fully parallel 8-bit data register and buffer
• Service request flip-flop interrupt generation
• Low input load current - 0.25 mA max.
• Three state outputs
• Outputs sink 15 mA
• 3.65V output high voltage for direct interface to 8008, 8080A or 8085A CPU
• Asynchronous register clear
• Replaces buffers, latches and multiplexers in microcomputer systems
• Reduces system package count
