Octal D-Type Flip-Flop with 3-STATE Outputs
General Description
The AC/ACT374 is a high-speed, low-power octal D-type
flip-flop featuring separate D-type inputs for each flip-flop
and 3-STATE outputs for bus-oriented applications. A buff-
ered Clock (CP) and Output Enable (OE) are common to
all flip-flops.
