74ACTQ16541

16-Bit Buffer/Line Driver with 3-STATE Outputs

General Description

The ACTQ16541 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 byte controlled. Each byte

has separate 3-STATE control inputs which can be shorted

together for full 16-bit operation.

The ACTQ16541 utilizes Fairchild Quiet Series

 technol-

ogy to guarantee quiet output switching and improved

dynamic threshold performance. FACT Quiet Series

 fea-

tures 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 16-bit version of the ACTQ541

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

Ordering Code:

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