SN74ALS623ADW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS623ADW is an octal bus transceiver from the Texas Instruments ALS logic family, housed in a 20-pin SOIC (DW) package. It provides asynchronous two-way communication between data buses with 3-state true outputs. The device operates on a supply voltage of 4.5 V to 5.5 V and supports a propagation delay of up to 13 ns. It features dual output-enable inputs for flexible timing control and isolation capabilities.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports asynchronous two-way communication between data buses

• Provides local bus-latch capability by simultaneously enabling both directions

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous two-way communication between data buses
• Local bus-latch applications requiring simultaneous bidirectional enablement
• System designs utilizing ALS logic families for bus interfacing

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the component matches the SN74ALS623ADW designation specifically, as other variants like SN74ALS620A or SN74ALS621A exist within the same series but differ in output type. Confirm the SOIC-20 package style and ensure the operating temperature range meets the 0°C to 70°C requirement. Check for RoHS compliance status if environmental regulations apply to the assembly process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this part when true logic outputs are required for octal bus applications. Unlike the SN74ALS620A which offers inverting outputs, or the SN74ALS621A which uses open-collector outputs, the SN74ALS623A provides standard 3-state true outputs. Ensure the design accommodates the specific propagation delays and current drive capabilities defined for the ALS series.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the SN74ALS62xA series of octal bus transceivers manufactured by Texas Instruments. The series includes variants such as the SN74ALS620A, SN74ALS621A, and SN74AS623. These devices share similar functional descriptions regarding bus communication but differ in output configurations and electrical characteristics.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the SN74ALS623ADW achieve local bus-latch capability?

It achieves this by simultaneously enabling both output-enable inputs (OEAB and OEBA), allowing the device to store data while reinforcing its input.

What is the difference between SN74ALS623A and SN74ALS620A?

The SN74ALS623A provides 3-state true outputs, whereas the SN74ALS620A provides 3-state inverting outputs.
