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
tures GTO
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
