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

Functional Description
The ACTQ827 line driver is designed to be employed as
memory address driver, clock driver and bus-oriented
transmitter/receiver. The devices have 3-STATE outputs
controlled by the Output Enable (OE) pins. When the OE is
LOW, the device is transparent. When OE is HIGH, the
device is in 3-STATE mode.

Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, with-
out exception, to ensure that the system design is reliable over its power
supply, temperature, and output/input loading variables. Fairchild does not
recommend operation of FACT™ circuits outside databook specifications.
