DM74ALS151M

Overview

The DM74ALS151M is a 1-of-8 line data selector/multiplexer manufactured by onsemi. It features full on-chip decoding to select one of eight data sources based on a three-bit binary code at the Select inputs (C, B, A). The device provides two complementary outputs: Y (non-inverting) and W (inverting). A Strobe input disables all data inputs when high, forcing Y low and W high. It operates within a supply voltage range of 4.5 V to 5.5 V and an ambient temperature range of 0 °C to +70 °C. Propagation delays from data inputs to output range from 3 ns to 15 ns.

Feature Summary

• Advanced oxide-isolated, ion-implanted Schottky TTL process for improved performance
• Switching performance guaranteed over the full temperature and supply voltage range
• Pin and functional compatibility with LS family counterparts
• Internal overlap features in Select input buffers prevent invalid output transients during selection changes

Applications

• Data routing and selection systems requiring 8-to-1 multiplexing
• Digital logic circuits utilizing complementary signal buffering
• Systems requiring strobe-controlled data gating or disabling

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package type matches requirements, as the M suffix indicates SOIC-16 packaging. Check for tape and reel availability if automated assembly is required. Ensure compliance with RoHS directives and verify that the part meets specific environmental operating conditions before integration into final designs.

Selection Notes

Select this component when an 8-channel multiplexer with complementary outputs is needed. It is suitable for applications requiring pin-compatible upgrades from LS series devices. Consider the propagation delay specifications relative to system timing requirements. Verify that the operating temperature range aligns with the intended deployment environment.

Part Context

This device belongs to the 74ALS logic family, known for advanced Schottky technology offering higher speed than standard TTL while maintaining lower power consumption. The DM74ALS151 series is designed for general-purpose digital applications requiring reliable data selection and routing capabilities within standard industrial temperature ranges.
