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.

20 19

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.

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.
