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.

CLK

The eight flip-flops of the SN74AS4374B are

edge-triggered D-type flip-flops. On the second

positive transition of the clock (CLK) input, the Q

outputs are set to the logic levels set up at the data

(D) inputs.

The output-enable (OE) input does not affect internal operations of the flip-flops. Previously stored data can be

retained or new data can be entered while the outputs are in the high-impedance state.

The SN74AS4374B is characterized for operation from 0°C to 70°C.
