74F534 Octal D-Type Flip-Flop with 3-STATE Outputs
74F534
Octal D-Type Flip-Flop with 3-STATE Outputs
General Description
The 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 74F534 is the same as the 74F374 except that
the outputs are inverted.

Functional Description
The 74F534 consists of eight edge-triggered flip-flops with
individual D-type inputs and 3-STATE complementary 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 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.
