These octal D-type edge-triggered 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.  
SN54ALS374A, SN54AS374 . . . FK PACKAGE

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.

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.

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.
