description

The 74ACT11874 contains dual 4-bit registers featuring 3-state outputs designed specifically for bus driving. This makes this device particularly suitable for implementing buffer registers, I/O ports, and working registers.

The D-type edge-triggered flip-flops enter data on the low-to-high transition of the clock. The 74ACT11874 has inputs and noninverting outputs. Taking low causes the four Q outputs to go low independently of the clock.

The 74ACT11874 is characterized for operation from - 40°C to 85°C.
