description  
GND  
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 BCT574 are  
edge-triggered D-type flip-flops. On the positive  
transition of the clock (CLK) input, the Q outputs  
will be 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 logic levels) 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 increased drive provide  
the capability to drive bus lines without need for interface or pullup components.  
The output enable (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 SN54BCT574 is characterized for operation over the full military temperature range of 55°C to 125°C. The  
SN74BCT574 is characterized for operation from 0°C to 70°C.
