CD74HCT153EE4

Overview

The CD74HCT153EE4 is a dual 4-to-1-line selector/multiplexer manufactured by Texas Instruments. It belongs to the HCT logic series and operates within a supply voltage range of 4.5V to 5.5V. The device features two independent multiplexers sharing common select inputs (S0, S1) and separate enable inputs (1E, 2E). When enabled, it routes one of four data inputs to the corresponding output. It utilizes a 16-pin PDIP package and supports an extended operating temperature range from -55°C to +125°C.

Feature Summary

• Dual 4-to-1-line multiplexer architecture with shared selection control
• Direct LSTTL input logic compatibility for seamless interface integration
• High noise immunity characteristics inherent to CMOS technology
• Wide industrial and military-grade operating temperature capability

Applications

• Data routing in digital communication systems
• Address decoding in microprocessor-based designs
• Signal switching in test and measurement equipment
• I/O expansion in embedded controller architectures

Procurement Notes

Verify that the ordering suffix 'E4' corresponds to the specified lead-free and RoHS-compliant packaging configuration. Confirm the component status as active production on official manufacturer channels. Ensure the procurement documentation explicitly references the full part number CD74HCT153EE4 to distinguish it from non-environmental variants or obsolete packages.

Selection Notes

Select this component when direct LSTTL compatibility is required alongside low power consumption. The HCT series ensures voltage level matching with legacy TTL logic families. Verify that the 16-pin PDIP package aligns with the target printed circuit board layout constraints and thermal management requirements for the specific application environment.

Part Context

This device is part of the CD54/CD74HC(T)153 family of high-speed CMOS logic circuits. The '74' prefix indicates commercial grade availability, while the 'HCT' designation specifies High-speed CMOS with TTL-compatible inputs. This family provides balanced propagation delays and transition times suitable for general-purpose digital signal processing tasks.

Replacement Considerations

CD74HCT153E serves as the standard non-environmental variant. CD74HC153EE4 offers HC logic levels instead of HCT. CD54HCT153F3A represents the military-grade equivalent in ceramic packaging.
