description

GND 10

11 CLK

These octal edge-triggered D-type flip-flops

feature 3-state outputs designed specifically for

bus driving. They are particularly suitable for

implementing buffer registers, I/O ports,

bidirectional bus drivers, and working registers.

The eight flip-flops enter data on the low-to-high

transition of the clock (CLK) input.

A buffered output-enable (OE) input can be used

to place the eight outputs in either a normal logic

state (high or low logic levels) or the

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 interface or pullup components.

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 in the high-impedance state.

The SN54HCT574 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74HCT574 is characterized for operation from –40°C to 85°C.
