74F821 - Bus interface registers

Datasheet Summary

Description

The 74F821 series bus interface registers are designed to eliminate the extra packages required to buffer existing registers and provide extra data width for wider data/address paths of busses carrying parity.

Features

  • flip-flops.
  • High speed parallel registers with positive edge-triggered D-type.
  • High performance bus interface buffering for wide data/address paths or busses carrying parity.
  • High impedance PNP base inputs for reduced loading (20µA in high and low states).
  • IIL is 20µA vs 1000µA for AM29821 series.
  • Buffered control inputs to reduce AC effects.
  • Ideal where high speed, light loading, or increased fan-in as required with MOS microprocessor.
