DM74ALS153SJX

Signal Switches, Multiplexers, Decoders Overview

The DM74ALS153SJX is a dual 1-of-4 line data selector/multiplexer manufactured by onsemi. It features two independent multiplexing circuits with common select inputs A and B, separate data and strobe inputs, and non-inverting outputs. The device utilizes an advanced oxide-isolated, ion-implanted Schottky TTL process. It operates within a supply voltage range of 4.5V to 5.5V and supports a free air operating temperature of 0°C to +70°C. The component is housed in a 16-SOP package.

Signal Switches, Multiplexers, Decoders Feature Summary

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

Signal Switches, Multiplexers, Decoders Applications

• Data routing in digital logic systems
• Signal selection using binary codes
• Multiplexing applications requiring high-speed switching

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the DM74ALS153SJX is no longer in production as indicated by distributor records. Confirm functional equivalence with available substitutes such as SN74ALS153NSR or SN74AS153NSR before procurement. Ensure the selected replacement matches the 16-SOP package and electrical specifications required for your design.

Signal Switches, Multiplexers, Decoders Selection Notes

This component is suitable for designs requiring dual 4-to-1 multiplexing with Schottky TTL compatibility. It offers improved output transient handling and guaranteed switching performance across the full temperature and supply voltage range. Consider pin and functional compatibility with LS family counterparts if upgrading existing designs.

Signal Switches, Multiplexers, Decoders 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.

What is the function of the Select inputs?

The Select inputs A and B are common to both sections and use a unique two-bit binary code to select one-of-four data sources.
