description  
The ′BCT534 is an 8-bit flip-flop with 3-state  
outputs designed specifically for driving highly  
capacitive or relatively low-impedance loads. It is  
particularly suitable for implementing buffer  
registers, I/O ports, bidirectional bus drivers, and  
working registers.

The eight flip-flops of the ′BCT534 are  
edge-triggered D-type flip-flops. On the positive  
transition of the clock, the Q outputs will be set to  
the complement of the logic levels that were set up  
at the data (D) inputs. The ′BCT534 provides  
inverted data at its outputs.

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-imped-  
ance 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 the internal operations of the flip-flop. Previously stored data can  
be retained or new data can be entered while the outputs are in the high-impedance state.  
The SN54BCT534 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74BCT534 is characterized for operation from 0°C to 70°C.
