CD74HCT158E

Overview

The CD74HCT158E is a high-speed CMOS logic quad 2-input multiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features a PDIP-16 package. The device supports through-hole mounting and functions across an extended temperature range from -55 °C to +125 °C. It integrates four independent multiplexing circuits, each selecting one of two data inputs based on control signals.

Feature Summary

• Integrates four independent 2-to-1 multiplexers for parallel signal routing
• Utilizes high-speed CMOS technology for efficient power consumption
• Compatible with standard TTL logic levels via HCT series design

Applications

• Data selection in digital logic systems
