SN54AS873A - Dual 4-Bit D-Type Latches

Download the SN54AS873A datasheet PDF. This datasheet also covers the SN54ALS873B variant, as both devices belong to the same dual 4-bit d-type latches family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

SN54ALS873B, SN54AS873A, SN74ALS873B, SN74AS873A DUAL 4ĆBIT DĆTYPE LATCHES WITH 3ĆSTATE OUTPUTS SDAS036D − APRIL 1982 − REVISED AUGUST 1995 • 3-State Buffer-Type Outputs Drive Bus Lines Directly • Bus-Structured Pinout • Package Options Include Plastic Small-Outline (DW) Packages, Ceramic Chip Carriers (FK), and Plastic (NT) and Ceramic (JT) DIPs description 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.
