SN74HC151PW

Overview

The SN74HC151PW is an 8-to-1 line data selector/multiplexer from the Texas Instruments SN74HC series. It provides complete binary decoding to select one of eight data sources. The device operates within a supply voltage range of 2 V to 6 V and features a propagation delay of 63 ns. It is housed in a 16-pin TSSOP package with surface-mount installation. The component supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Provides complete binary decoding for selecting one of eight data inputs
• Enables input selection via low logic level on the strobe (G) input
• Forces standard output low and inverted output high when strobe is high

Applications

• Data source selection
• Demultiplexing operations
• Parallel-to-serial conversion
• Boolean function generation

Procurement Notes

Verify current production status as the SN74HC151PW has been identified as obsolete or end-of-life in available records. Confirm availability through authorized distributors or check for direct replacement alternatives such as the SN74HC151PWR before finalizing procurement plans. Ensure compliance with RoHS standards if required by specific project constraints.

Selection Notes

Select this component for applications requiring an 8-channel multiplexer with HC logic speed and voltage compatibility. The TSSOP-16 package suits space-constrained surface-mount designs. Consider the 63 ns propagation delay and 2V to 6V operating range against system requirements. Verify that the single-circuit configuration meets the signal routing needs without requiring additional external components.

Part Context

This part belongs to the SN74HC151 family, which includes variants like the SN74HC151DR in SOIC-Narrow packages. While sharing identical logical functionality and electrical specifications, the PW suffix specifically denotes the TSSOP-16 physical footprint. This distinction is critical for PCB layout compatibility and thermal management considerations in dense surface-mount assemblies.

Replacement Considerations

The SN74HC151PWR is listed as a direct substitute offering identical functionality in a tape-and-reel package format.
