description

This 8-bit flip-flop features 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 SN64BCT374 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 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 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 outputs are in a high-impedance state during power up and power down when the supply voltage is less

than approximately 3 V.

The SN64BCT374 is characterized for operation from −ā40°C to 85°C and 0°C to 70°C.
