Product Summary
The SN74ALS873BDW is a dual 4-bit D-type latch which features 3-state outputs designed specifically for bus driving. The SN74ALS873BDW is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The dual 4-bit latch is transparent D-type latch. 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 are latched. When the clear (CLR) input goes low, the Q outputs go low independently of LE.
