description

These dual 4-bit registers feature 3-state outputs designedspecifically for bus driving. This makes these devices particularlysuitable for implementing buffer registers, I/O ports, bidirectionalbus drivers, and working registers.

The dual 4-bit latch is transparent D-type. When the latch enableinput (1C or 2C) is high, the (Q) outputs will follow the data (D)inputs in true form, according to the function table. When the latchenable input is taken low, the outputs will be latched. When goes low, the Q outputs go lowindependently of enable C. The outputs are in a high-impedance statewhen (outputcontrol) is at a high logic level.

The 74ACT11873 is characterized for operation from - 40°C to85°C.
