Product data sheet
74F821
10-bit bus interface register, non-inverting (3-State)
2
2004 Jul 22
FEATURES
High speed parallel registers with positive edge-triggered D-type
flip-flops
High performance bus interface buffering for wide data/address
paths or buses carrying parity
High-impedance PNP base inputs for reduced loading (20 A in
HIGH and LOW states)
I
IL is 20 A versus 1000 A 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
Outputs sink 64 mA and source 24 mA
DESCRIPTION
The 74F821 bus interface register is designed to eliminate the extra
packages required to buffer existing registers and provide extra data
width for wider data/address paths of buses carrying parity.
The 74F821 is a buffered 10-bit wide version of the popular
74F374/74F534 functions.
