54ACTQ543
Quiet Series Octal Registered Transceiver with
TRI-STATE^® Outputs
General Description
The ACTQ543 is a non-inverting octal transceiver containing
two sets of D-type registers for temporary storage of data
flowing in either direction. Separate Latch Enable and Out-
put Enable inputs are provided for each register to permit in-
dependent input and output control in either direction of data
flow.
The ACTQ utilizes NSC Quiet Series technology to guaran-
tee quiet output switching and improved dynamic threshold
performance. FACT Quiet Series™ features GTO™ output
control and undershoot corrector in addition to a split ground
bus for superior performance.
Features
