SN74HC158PWR

Overview

The SN74HC158PWR is a quad 2-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature from -40°C to +85°C. The device features inverted outputs capable of driving up to 15 LSTTL loads, with typical propagation delay of 11 ns at 5 V. It includes a separate strobe input for enabling or disabling the selected data. Packaged in a 16-pin TSSOP (PW) format, it consumes low power with maximum ICC of 80 µA.

Feature Summary

• Contains four independent multiplexers that select between two data sources based on a common select line.
• Features a dedicated strobe input that disables all outputs when activated.
• Provides inverted logic outputs suitable for direct interfacing with standard logic families.

Applications

• Data routing in digital communication systems
• Address decoding circuits
• Signal switching in instrumentation

Procurement Notes

Verify the active production status and RoHS compliance via the latest TI Package Option Addendum before procurement. Confirm the specific tape and reel dimensions match your automated assembly equipment requirements. Ensure the ordering suffix corresponds to the desired packaging quantity and moisture sensitivity level rating.

Selection Notes

Select this component for applications requiring wide voltage operation and low power consumption. The HC series offers higher speed compared to older HCT variants while maintaining CMOS noise immunity. Verify that the TSSOP package height and pin pitch align with your PCB layout constraints and thermal management strategy.

Part Context

This part belongs to the SN74HC158 family of high-speed CMOS logic devices. It is functionally compatible with other industry-standard quad multiplexers but offers specific Texas Instruments manufacturing tolerances and packaging options. The PW suffix indicates the Thin Shrink Small Outline Package variant.

FAQ

What is the function of the G input?

The G input acts as a strobe; when high, it disables all outputs regardless of the select inputs.

Are the outputs inverted?

Yes, the SN74HC158 provides inverted data outputs relative to the selected input lines.
