12 5Q

These octal D-type edge-triggered flip-flops

feature 3-state outputs designed specifically for

GND

CLK

driving

highly

capacitive

relatively

low-impedance loads. They are particularly

suitable for implementing buffer registers, I/O

ports, bidirectional bus drivers, and working

registers.

SN54ALS374A, SN54AS374 . . . FK PACKAGE

(TOP VIEW)

On the positive transition of the clock (CLK) input,

the Q outputs are set to the logic levels set up at

the data (D) inputs.

20 19

A buffered output-enable (OE) input places 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 the increased drive

provide the capability to drive bus lines without

interface or pullup components.

9 10 11 12 13

OE does not affect 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 SN54ALS374A and SN54AS374 are characterized for operation over the full military temperature range

of –55°C to 125°C. The SN74ALS374A and SN74AS374 are characterized for operation from 0°C to 70°C.
