description

These dual 4-bit D-type latches feature 3-state outputs designedspecifically for bus driving. These devices are particularly suitablefor implementing buffer registers, I/O ports, bidirectional busdrivers, and working registers.

The dual 4-bit latches are transparent D-type latches. While thelatch-enable (LE) input is high, the Q outputs follow the data (D)inputs in true form, according to the function table. When LE is low,the outputs are latched. When the clear () input goes low, the Q outputs golow independently of LE. The outputs are in the high-impedance statewhen the output-enable ()input is at a high logic level.

The SN54ALS873B and SN54AS873A are characterized for operationover the full military temperature range of -55°C to 125°C.The SN74ALS873B and SN74AS873A are characterized for operation from0°C to 70°C.
