74F821
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. The 74F821/74F822 are buffered 10-bit wide versions of the popular 74F374/74F534 functions.
Key Features
- 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
- Positive and negative over-shoots are clamped to ground
- 3-State outputs glitch free during power-up and power-down
- Slim Dip 300 mil package
- Broadside pinout compatible with AMD AM 29821-29826 series
