74ACTQ16244
16-Bit Buffer/Line Driver with 3-STATE Outputs
General Description
The ACTQ16244 contains sixteen non-inverting buffers
with 3-STATE outputs designed to be employed as a mem-
ory and address driver, clock driver, or bus oriented trans-
mitter/receiver. The device is nibble controlled. Each nibble
has separate 3-STATE control inputs which can be shorted
together for full 16-bit operation.
The ACTQ16244 utilizes Fairchild’s Quiet Series technol-
ogy to guarantee quiet output switching and improved
dynamic threshold performance. FACT Quiet Series fea-
tures GTO output control for superior performance.
Features
s Utilizes Fairchild’s FACT Quiet Series technology
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
s Guaranteed pin-to-pin output skew
s Separate control logic for each byte and nibble
s 16-bit version of the ACTQ244
s Outputs source/sink 24 mA
s Additional specs for multiple output switching
s Output loading specs for both 50 pF and 250 pF loads

Functional Description
The ACTQ16244 contains sixteen non-inverting buffers
with 3-STATE standard outputs. The device is nibble
(4 bits) controlled with each nibble functioning identically,
but independent of the other. The control pins can be
shorted together to obtain full 16-bit operation. The 3-
STATE outputs are controlled by an Output Enable (OEn)
input for each nibble. When OEn is LOW, the outputs are in
2-state mode. When OEn is HIGH, the outputs are in the
high impedance mode, but this does not interfere with
entering new data into the inputs.
