Dual 4-bit D-type Latches With 3-state Outputs

  These dual 4-bit D-type Latches 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 ? 55?C to 125?C. The SN74ALS873B and SN74AS873A are characterized for operation from 0?C to 70?C.
