DM74ALS153SJ

Overview

The DM74ALS153SJ is a dual 1-of-4 line data selector/multiplexer manufactured by onsemi. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating free air temperature range of 0°C to +70°C. The device utilizes Advanced oxide-isolated, ion-implanted Schottky TTL process technology. It features two independent multiplexer circuits with common Select inputs A and B, separate Data and Strobe inputs, and non-inverting output buffers. Propagation delays from Select to Output range from 5ns to 21ns, while data path delays range from 3ns to 15ns.

Feature Summary

• Contains full on-chip decoding to select one-of-four data sources based on unique two-bit binary codes at the Select inputs.
• Incorporates internal overlap features in Select input buffers to prevent invalid output transients during input changes.
• Strobe inputs disable associated data inputs when HIGH, forcing the corresponding output to the LOW state.

Applications

• Data routing and selection in digital logic systems
• Signal switching applications requiring high-speed performance
• Multiplexing multiple data sources into a single output channel

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm package type matches the SOP-16 specification (EIAJ TYPE II, 5.3mm wide). Check for RoHS compliance status as indicated in current documentation. Ensure storage conditions adhere to recommended limits to maintain device integrity prior to assembly.

Selection Notes

Select this component for designs requiring pin and functional compatibility with LS family counterparts. Consider its improved output transient handling capability for robust signal integrity. Verify that the required propagation delay specifications fall within the guaranteed ranges across the full temperature and VCC supply range.

Part Context

This device belongs to the 74ALS logic family, known for advanced Schottky TTL performance. It serves as a standard logic IC for data selection tasks. The SJ suffix denotes the specific 16-Lead Small Outline Package (SOP) variant, distinguishing it from SOIC or PDIP packages within the same logical function family.

FAQ

How does the Strobe input affect the output?

When the Strobe input is at the HIGH level, it disables the associated data inputs and forces the corresponding output to the LOW state.

Are the Select inputs shared between the two multiplexers?

Yes, the Select inputs A and B are common to both sections of the dual multiplexer.
