FAST AND LS TTL DATA
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.

FUNCTIONAL DESCRIPTION
The F534 consists of eight edge-triggered flip-flops with
individual D-type inputs and 3-state true outputs. 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
inputs that meet the setup and hold times 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 outputs. 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.
