74ACTQ18825 18-Bit Buffer/Line Driver with 3-STATE Outputs
September 1991
Revised January 2000
74ACTQ18825
18-Bit Buffer/Line Driver with 3-STATE Outputs
General Description
The ACTQ18825 contains eighteen 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 byte controlled. Each byte
has separate 3-STATE control inputs which can be shorted
together for full 18-bit operation.
The ACTQ18825 utilizes Fairchild FACT Quiet Series鈩?/div>
technology to guarantee quiet output switching and
improved dynamic threshold performance. FACT Quiet
Series features GTO鈩?output control and undershoot cor-
rector for superior performance.
