description

This dual 4-bit D-type edge-triggered flip-flop features 3-state outputs designed specifically for bus driving. This makes these devices particularly suitable for implementing buffer registers, I/O ports, and working registers.

The flip-flops enter data on the low-to-high transition of the clock. The 74AC11874 has clear (1 and 2) inputs and noninverting outputs. Taking low causes the four Q outputs to go low independently of the clock.

The 74AC11874 is characterized for operation from -40°C to 85°C.
