- Stores 16- bit wide data inputs, multiplexed 8- bit outputs
The 74F1604 is a dual octal transparent latch. Organized as 8- bit A and B latches, the latch outputs are connected by pairs to eight 2- input multiplexers. A select (SELECT A/B) input determines whether the A or B latch contents are multiplexed to the eight outputs. Data from the B inputs are selected when SELECT A/B is low; data from the A inputs are selected when SELECT A/B is high. Data enters the latch on the falling edge of the latch enable (LE) input. The latch remains transparent to the data inputs while LE is low, and stores the data that is present one setup...
