CD74HCT153EG4

Overview

The CD74HCT153EG4 is a dual 4-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It belongs to the 74HCT logic series, utilizing high-speed CMOS technology with TTL-compatible inputs. The device operates on a single power supply ranging from 4.5V to 5.5V and supports an operating temperature range of -55°C to 125°C. It features two independent multiplexers within a single package, providing four data inputs and one output per multiplexer, controlled by two select lines. The component is RoHS compliant and lead-free.

Feature Summary

• Dual independent 4-to-1 multiplexer architecture
• High-speed CMOS construction with TTL-compatible input levels
• Wide operating temperature range for industrial applications
• Single power supply operation

Applications

• Data routing in digital systems
• Signal selection in measurement equipment
• Logic function implementation in control circuits

Procurement Notes

Verify that the ordering suffix 'G4' confirms RoHS compliance and lead-free status as specified by Texas Instruments. Ensure the package type matches the required PCB footprint, typically associated with the E suffix indicating a specific surface-mount or through-hole configuration depending on the full part code interpretation. Confirm availability status as distribution channels may list variants with different suffixes.

Selection Notes

Select this component when dual 4-to-1 multiplexing is required with HCT logic compatibility. It serves as a direct replacement for standard 74HCT153 devices in designs needing wide temperature tolerance. Consider the pinout and package dimensions relative to existing board layouts. Verify input voltage levels align with the system's logic family to ensure proper interfacing without additional level shifting.

Part Context

This device is part of the Texas Instruments 74HCT series of logic integrated circuits. The 74HCT series is designed to interface directly with TTL circuits while offering the low power consumption advantages of CMOS technology. The 153 variant specifically provides dual multiplexer functionality, commonly used in digital logic design for selecting between multiple data sources.

Replacement Considerations

Publicly confirmed substitute part numbers include CD74HCT153E, CD74HCT153M, CD74HCT153MT, and CD74HCT153M96. These alternatives offer equivalent electrical characteristics and pinouts, allowing for cross-manufacturer or packaging-based substitution within the same logic family.
