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 F374 are edge-triggered  
D-type flip-flops. On the positive transition of the  
clock (CLK) input, the Q outputs are set to the logic  
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.
