SN74HC151PWR

Overview

The SN74HC151PWR 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 utilizes a 16-pin TSSOP surface-mount package and supports operation temperatures from -40°C to +85°C. The component delivers standard logic outputs with low input current characteristics.

Feature Summary

• Provides complete binary decoding for selecting one of eight data inputs
• Enables high-speed data routing and selection functions
• Supports low-power consumption with minimal input current requirements

Applications

• Data source selection in digital systems
• Parallel-to-serial data conversion
• Boolean function generation

Procurement Notes

Verify the specific suffix PWR indicates the tape-and-reel packaging format upon ordering. Confirm that the 16-TSSOP footprint matches the target PCB layout dimensions. Ensure the operating environment remains within the specified -40°C to +85°C temperature range for reliable performance. Check for any recent product change notices regarding manufacturing site updates.

Selection Notes

Select this component when an 8-channel multiplexer is required with HC logic compatibility. It is suitable for applications needing a wide voltage range between 2 V and 6 V. Consider the TSSOP-16 package for space-constrained surface-mount designs. Verify that the 63 ns propagation delay meets the system timing requirements.

Part Context

This part belongs to the SN74HC family of high-speed CMOS logic devices manufactured by Texas Instruments. It serves as a standard 8-to-1 multiplexer, functioning similarly to other variants like the SN74HC151DR which uses a different package. The device is designed for general-purpose digital logic applications requiring efficient data routing.

Replacement Considerations

The SN74HC151PW is a direct pin-compatible alternative available in a tube package. Other family members such as the SN74HC151DR offer identical functionality in a SOIC-Narrow-16 package.
