Procurement Notes

Verify the manufacturer designation, as National Semiconductor was acquired by Texas Instruments. Confirm RoHS compliance status and check for active production status, as some sources indicate this specific part number may be discontinued or obsolete. Ensure the package type matches the required 16-pin DIP configuration.

Selection Notes

Select this component when a 3-to-8 decoder with input latching is required. Consider the ALS series speed and power characteristics relative to system needs. Verify compatibility with standard TTL logic levels and ensure the operating temperature range meets environmental requirements.

Part Context

This component belongs to the 74ALS (Advanced Low-power Schottky) logic family. It serves as a digital logic IC designed for high-speed switching applications while maintaining lower power consumption compared to standard TTL counterparts. The device is widely used in digital systems requiring address decoding.

Replacement Considerations

Check for equivalents such as the DM74ALS137M (SOIC package variant). Verify functional compatibility with other 74ALS137 derivatives from different manufacturers, ensuring pinout and electrical specifications align.
