description

These 8-bit flip-flops feature 3-state outputs

designed specifically for driving highly capacitive

or relatively low-impedance loads. They are

particularly suitable for implementing buffer

registers, I/O ports, bidirectional bus drivers, and

working registers.

(TOP VIEW)

The eight flip-flops of the ′F534A are

edge-triggered D-type flip-flops. On the positive

transition of the clock, the Q outputs are set to the

complement of the logic states that were set up at

the data (D) inputs. The ′F534A is equivalent to the

′F374 except for having inverted outputs.

20 19

A buffered output enable (OE ) control input can

be used to place the eight outputs in either a

normal logic state (high or low logic levels) or a

high-impedance state. In the high-impedance

state, the outputs neither load nor drive the bus

lines significantly. The high-impedance state and

increased drive provide the capability to drive bus

lines without need for interface or pullup

components.

9 10 11 12 13

The output enable (OE) does not affect the internal operations of the flip-flops. Old data can be retained or new

data can be entered while the outputs are off.

The SN54F534A is characterized for operation over the full military temperature range of −55°C to 125°C. The

SN74F534A is characterized for operation from 0°C to 70°C.
