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
a73 Utilizes Fairchild’s FACT Quiet Series technology
a73 Guaranteed simultaneous switching noise level and
dynamic threshold performance
a73 Guaranteed pin-to-pin output skew
a73 Separate control logic for each byte and nibble
a73 16-bit version of the ACTQ244
a73 Outputs source/sink 24 mA
a73 Additional specs for multiple output switching
a73 Output loading specs for both 50 pF and 250 pF loads
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
