SN74HC151DE4

Overview

The SN74HC151DE4 is an 8-to-1 line data selector/multiplexer from the Texas Instruments HC logic family. It operates within a supply voltage range of 2 V to 6 V and features a propagation delay of 63 ns. The device is housed in a 16-pin SOIC-Narrow package and supports surface mount installation. It functions across a temperature range of -40°C to +85°C, providing one circuit with eight inputs and a single output.

Feature Summary

• Provides complete binary decoding to select one of eight data sources
• Features a strobe input that forces standard output low and inverted output high when active
• Capable of driving up to ten LSTTL loads

Applications

• Data source selection
• Demultiplexing operations
• High-speed operation circuits
• Low-power system designs

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as this specific part number may be subject to discontinuation. Ensure packaging specifications match design requirements before finalizing orders.

Selection Notes

Select this component for applications requiring 8-to-1 multiplexing within the HC logic family. Consider the SOIC-Narrow package constraints and operating voltage limits. Evaluate thermal performance within the specified temperature range and ensure compatibility with existing logic levels in the target circuit design.

Part Context

This device belongs to the SN74HC151 series of data selectors. It shares functional characteristics with other members of the 74HC family but differs in physical packaging. The DE4 suffix indicates a specific tape-and-reel or tube packaging variant compliant with environmental standards, distinct from non-E4 counterparts.

Replacement Considerations

SN74HC151PW serves as a pin-compatible alternative using a TSSOP-16 package. SN74HC151PWR offers a similar function in a different surface-mount configuration. Verify electrical parameters and mechanical dimensions before substituting.
