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
a73 Guaranteed simultaneous switching noise level and
dynamic threshold performance
a73 Guaranteed pin-to-pin skew AC performance
a73 Inputs and outputs on opposite sides of package allow
easy interface with microprocessors
a73 Improved latch-up immunity
a73 Outputs source/sink 24 mA
a73 Functionally and pin-compatible to AMD’s AM29827
a73 Has TTL-compatible inputs
