74ACQ543• 74ACTQ543
Quiet Series Octal Registered Transceiver
with 3-STATE Outputs
General Description
The ACQ/ACTQ543 is a non-inverting octal transceiver
containing two sets of D-type registers for temporary stor-
age of data flowing in either direction. Separate Latch
Enable and Output Enable inputs are provided for each
register to permit independent input and output control in
either direction of data flow.
The ACQ/ACTQ utilizes Fairchild Quiet Series technol-
ogy to guarantee quiet output switching and improved
dynamic threshold performance FACT Quiet Series fea-
tures GTO output control and undershoot corrector in
addition to a split ground bus for superior performance.
Features
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
s Guaranteed pin-to-pin skew AC performance
s 8-bit octal latched transceiver
s Separate controls for data flow in each direction
s Back-to-back registers for storage
s Outputs source/sink 24 mA
s 300 mil slim PDIP/SOIC

Note 14: Skew is defined as the absolute value of the difference between the actual propagation delay for any two outputs within the same packaged device.
The specification applies to any outputs switching in the same direction, either HIGH-to-LOW (tOSHL) or LOW-to-HIGH (tOSLH). Parameter guaranteed by
design. Not tested.
