54ACTQ16240
16-Bit Inverting Buffer/Line Driver with TRI-STATE^®
Outputs
General Description
The ’ACTQ16240 contains sixteen inverting buffers with
TRI-STATE outputs designed to be employed as a memory
and address driver, clock driver, or bus-oriented transmitter/
receiver. The device is nibble controlled. Each nibble has
separate TRI-STATE control inputs which can be shorted to-
gether for full 16-bit operation.
The ’ACTQ16240 utilizes NSC Quiet Series technology to
guarantee quiet output switching and improve dynamic
threshold performance. FACT Quiet Series™ features
GTO™ output control for superior performance.
