74ACTQ827

Quiet Series

™ 10-Bit Buffer/Line Driver

with 3-STATE Outputs

General Description

The ACTQ827 10-bit bus buffer provides high performance

bus interface buffering for wide data/address paths or

buses carrying parity. The 10-bit buffers have NOR output

enables for maximum control flexibility. The ACTQ827 uti-

lizes Fairchild Quiet Series

™ technology to guarantee quiet

output switching and improved dynamic threshold perfor-

mance. FACT Quiet Series

™ features GTO™ output control

and undershoot corrector in addition to a split ground bus

for superior performance.

Features

s Guaranteed simultaneous switching noise level and

dynamic threshold performance

s Guaranteed pin-to-pin skew AC performance

s Inputs and outputs on opposite sides of package allow

easy interface with microprocessors

s Improved latch-up immunity

s Outputs source/sink 24 mA

s Functionally and pin-compatible to AMD’s AM29827

s Has TTL-compatible inputs
