SN74HC158NSR

Overview

The SN74HC158NSR is a Texas Instruments HC-series quad 2-input multiplexer in a 16-pin SOP package. It operates on a supply voltage range of 2 V to 6 V with a maximum static current of 80 µA. The device provides inverted outputs capable of driving up to 15 LSTTL loads, featuring ±6 mA output drive at 5 V and low input current of 1 µA max. Typical propagation delay is 11 ns. It functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides full data selection from two sources to four inverted outputs via separate strobe control
• Supports wide operating voltage range from 2 V to 6 V for flexible system integration
• Features low power consumption with minimal static current draw during operation

Applications

• Data routing between multiple sources to single destinations
• Address decoding logic circuits
• Parallel-to-serial conversion interfaces

Procurement Notes

Verify the specific ordering suffix 'NSR' corresponds to the SOP-16 package and reel quantity of 2000 units. Confirm RoHS compliance status and moisture sensitivity level ratings prior to procurement. Ensure the component matches the active production status indicated in the latest packaging addendum.

Selection Notes

Select this component when a quad 2-input multiplexer with inverted outputs is required. It is suitable for applications needing wide voltage compatibility and low standby power. Verify that the SOP-16 package dimensions align with the target PCB layout constraints and thermal requirements.
