74ACTQ16540 16-Bit Inverting Buffer/Line Driver with 3-STATE Outputs
General Description
The ACTQ16540 contains sixteen inverting buffers with 3STATE outputs designed to be employed as a memory and address driver, clock driver, or bus-oriented transmitter/ receiver. The device is byte controlled. Each byte has separate 3-STATE control inputs which can be shorted together for full 16-bit operation. The ACTQ16540 utilizes Fairchild Quiet Series technology to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series features GTO output control for superior performance.
Features
s Utilizes Fairchild FACT Quiet Series technology s Guaranteed simultaneous switching noise level and dynamic threshold performance s Guaranteed pin-to-pin output skew s Separate control logic for each byte s Outputs source/sink 24 mA s Additional specs for multiple output switching s Output loading specs for both 50 pF and 250 pF loads
