54ACQ374 • 54ACTQ374
Quiet Series Octal D Flip-Flop with TRI-STATE® Outputs
General Description
The ’ACQ/’ACTQ374 is a high-speed, low-power octal
D-type flip-flop featuring separate D-type inputs for each
flip-flop and TRI-STATE outputs for bus-oriented applica-
tions. A buffered Clock (CP) and Output Enable (OE) are
common to all flip-flops.
The ’ACQ/’ACTQ374 utilizes Quiet Series technology to
guarantee quiet output switching and improve dynamic
threshold performance. FACT Quiet Series™ features
GTO™ output control and undershoot corrector in addition to
a split ground bus for superior performance.
Features
n ICC and IOZ reduced by 50%
n Guaranteed simultaneous switching noise level and
dynamic threshold performance
n Improved latch-up immunity
n Buffered positive edge-triggered clock
n TRI-STATE outputs drive bus lines or buffer memory
address registers
n Outputs source/sink 24 mA
n Faster prop delays than the standard ’AC/’ACT374
n 4 kV minimum ESD immunity
n Standard Military Drawing (SMD)
