SN74HC158PW

Overview

The SN74HC158PW is a quad 2-line to 1-line data selector/multiplexer manufactured by Texas Instruments in the HC logic series. It features a wide operating voltage range of 2 V to 6 V and outputs that can drive up to 15 LSTTL loads. The device provides inverted data outputs and includes a separate strobe (G) input for control. It operates within a temperature range of -40°C to +85°C and is housed in a 16-pin TSSOP package.

Feature Summary

• Contains four independent multiplexers with inverters and drivers for full data selection
• Provides inverted data outputs routed from selected sources
• Includes a dedicated strobe input for controlling output enablement

Applications

• Routing 4-bit words between two data sources
• General-purpose digital data selection circuits
• LSTTL load driving applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum, as the tube version may be obsolete while the reel version remains active. Confirm RoHS compliance and lead finish details directly from the datasheet or official distributor listings before finalizing procurement specifications.

Selection Notes

Select this component when a quad 2-to-1 multiplexer with inverted outputs is required. Ensure the application voltage falls within the 2 V to 6 V range. Verify that the TSSOP-16 package dimensions align with the PCB layout requirements and that the operating temperature range meets the environmental constraints.

Part Context

This part belongs to the SN74HC158 family of data selectors. It is functionally equivalent to other variants such as SN74HC158D and SN74HC158N, differing primarily in the physical package type. The PW suffix specifically denotes the Thin Shrink Small Outline Package (TSSOP).

Replacement Considerations

SN74HC158PWR is an active alternative available in the same TSSOP-16 package format.
