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 ′BCT374 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.  
14 6D  
9 10 11 12 13  
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 SN54BCT374 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74BCT374 is characterized for operation from 0°C to 70°C.
