Functional Description
The ACQ/ACTQ374 consists of eight edge-triggered flip-
flops with individual D-type inputs and 3-STATE true out-
puts. The buffered clock and buffered Output Enable are
common to all flip-flops. The eight flip-flops will store the
state of their individual D-type inputs that meet the setup
and hold time requirements on the LOW-to-HIGH Clock
(CP) transition. With the Output Enable (OE) LOW, the
contents of the eight flip-flops are available at the out-
puts. When the OE is HIGH, the outputs go to the high
impedance state. Operation of the OE input does not
affect the state of the flip-flops.
