OCTAL D-TYPE FLIP-FLOP
WITH 3-STATE OUTPUTS
The MC54 / 74F534 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 buffered Clock (CP) and Output Enable (OE) are
common to all flip-flops. The F534 is the same as the F374 except that the
outputs are inverted.
