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.

The eight flip-flops of the ′F374 are edge-triggered

D-type flip-flops. On the positive transition of the

clock (CLK) input, the Q outputs are set to thelogic

levels that were set up at the data (D) inputs.

A buffered output enable (OE) input can be used

to place the eight outputs in either a normal logic

state (high or low) 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 the increased drive

provide the capability to drive bus lines without

need for interface or pullup components.

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

data can be entered while the outputs are in the high-impedance state.

The SN74F374 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count

and functionality of standard small-outline packages in less than half the printed-circuit-board area.

The SN54F374 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74F374 is characterized for operation from 0°C to 70°C.
