Overview
SN54ABT16640, SN74ABT16640 16-BIT BUS TRANSCEIVERS WITH 3-STATE OUTPUTS SCBS107C – APRIL 1992 – REVISED JANUARY 1997 D Members of the Texas Instruments Widebus ™ Family D State-of-the-Art EPIC-ΙΙB™ BiCMOS Design Significantly Reduces Power Dissipation D Latch-Up Performance Exceeds 500 mA Per JEDEC Standard JESD-17 D Typical VOLP (Output Ground Bounce) < 1 V at VCC = 5 V, TA = 25°C D Distributed VCC and GND Pin Configuration Minimizes High-Speed Switching Noise D Flow-Through Architecture Optimizes PCB Layout D High-Drive Outputs (–32-mA IOH, 64-mA IOL ) D Package Options Include Plastic 300-mil Shrink Small-Outline (DL) and Thin Shrink Small-Outline (DGG) Packages, and 380-mil Fine-Pitch Ceramic Flat (WD) Package Using 25-mil Center-to-Center Spacings description The ’ABT16640 are inverting 16-bit transceivers designed for asynchronous communication between data buses.
These devices can be used as two 8-bit transceivers or one 16-bit transceiver.
It allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (1DIR and 2DIR) inputs.
The output-enable (1OE and 2OE) inputs can be used to disable the device so that the buses are effectively isolated.

The SN54ABT16640 is characterized for operation over the full military temperature range of –55°C to 125°C.
