description

This dual 4-bit transparent D-type latch features 3-state outputsdesigned specifically for bus driving. This makes these devicesparticularly suitable for implementing buffer registers, I/O ports,bidirectional bus drivers, and working registers.

When the latch-enable (1LE or 2LE) input is high, the Q outputswill follow the data (D) inputs in true form, according to thefunction table. When LE is taken low, the outputs will be latched.When the clear (1 or 2) input goes low, the Q outputs golow independently of LE. The outputs are in a high-impedance statewhen the output-control (1 or2) input is at ahigh logic level.

The 74AC11873 is characterized for operation from -40°C to85°C.
