Description

These dual 4-bit D-type latches feature 3-state outputs designed specifically for bus driving. This makes SN54ALS873B and SN54AS873 particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

The dual 4-bit latches are transparent D-type latches. While the latch-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 of SN54ALS873B and SN54AS873 are latched. When the clear (CLR) input goes low, the Q outputs go low independently of LE. The outputs of SN54ALS873B and SN54AS873 are in a high-impedance state when the output-enable (OE) input is at a high logic level.

The SN54ALS873B and SN54AS873 are characterized for operation over the full military temperature range of 55°C to 125°C. The SN74ALS873B and SN74AS873A are characterized for operation from 0°C to 70°C.
