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 Seriestechnol-
ogy to guarantee quiet output switching and improved
dynamic threshold performance. FACT Quiet Seriesfea-
tures GTOoutput 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

Functional Description
The ACTQ16541 contains sixteen non-inverting buffers
with 3-STATE standard outputs. The device is byte con-
trolled with each byte functioning identically, but indepen-
dent of the other. The control pins can be shorted together
to obtain full 16-bit operation. The 3-STATE outputs are
controlled by an Output Enable (OEn) input for each byte.
When OEn is LOW, the outputs are in 2-state mode. When
OEn is HIGH, the outputs are in the high impedance mode,
but this does not interfere with entering new data into the
inputs.

Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, with-
out exception to ensure that the system design is reliable over its power
supply, temperature, and output/input loading variables. Fairchild does not
recommend operation of FACTcircuits outside databook specifications.
