TRIPLE 3-INPUT POSITIVE-AND GATES

These dual 4-bit D-type Latches SN54ALS11A SN54AS11 SN74ALS11A SN74AS11 feature 3-state outputs designed specifically for bus driving. These devices are 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 are latched. When the clear (CLR) input goes low, the Q outputs go low independently of LE. The outputs are in the high-impedance state when the output-enable (OE) input is at a high Logic level. The SN54ALS873B and SN54AS873A are characterized for operation over the full military temperature range of 55C to 125C. The SN74ALS873B and SN74AS873A are characterized for operation from 0C to 70C.
