SN74HC158NE4

Overview

The SN74HC158NE4 is a quad 2-line 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 supports an operating temperature range of -40°C to +85°C. The device features inverted outputs, a separate strobe input for control, and can drive up to 15 LSTTL loads. Electrical characteristics include a maximum low-level output current of 6 mA at 5 V, typical propagation delay of 11 ns, and maximum input current of 1 µA.

Feature Summary

• Contains four independent multiplexers that select one of two data sources based on address inputs.
• Outputs provide inverted data signals with dedicated drivers for full data selection.
• Includes a separate strobe input to enable or disable the selected data routing.

Applications

• Data routing in digital logic circuits
• Address decoding systems
• Signal switching applications

Procurement Notes

Verify the active status of the SN74HC158NE4 directly through official Texas Instruments channels before procurement. Confirm compliance with RoHS standards and lead finish specifications (NIPDAU) as listed in the latest package addendum. Ensure the PDIP-16 tube packaging aligns with your assembly requirements. Cross-reference the specific ordering suffix to guarantee the correct material and environmental classification.

Selection Notes

Select this component when a quad multiplexer with inverted outputs is required for HC logic compatibility. The wide 2 V to 6 V supply range allows flexibility across various voltage domains. Verify that the 16-pin PDIP package fits the board layout constraints. Consider the 15 LSTTL load driving capability if interfacing with legacy TTL devices.

Part Context

This part belongs to the SN74HC158 series of data selectors manufactured by Texas Instruments. It is designed for general-purpose digital applications requiring multiple signal paths to be managed efficiently. The HC series ensures CMOS power consumption benefits while maintaining standard logic levels.

Replacement Considerations

SN74HC158N is a direct equivalent offering identical functionality in the same PDIP-16 package format without the E4 suffix designation.
