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鈥檚 Quiet Series technol-
ogy to guarantee quiet output switching and improved
dynamic threshold performance. FACT Quiet Series錚?fea-
tures GTO錚?output control for superior performance.
