CD74HCT153E

Overview

The CD74HCT153E is a dual 4-line to 1-line multiplexer belonging to the HCT series, manufactured by Harris Corporation. It features two independent multiplexing functions, each with four data inputs and one true output. The device utilizes CMOS technology and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 16-pin PDIP package and supports an operating temperature range from -55°C to 125°C. The propagation delay is specified at 51 ns.

Feature Summary

• Dual independent multiplexing functionality
• CMOS construction for low power consumption
• True output polarity
• Wide operating temperature capability

Applications

• Data routing in digital systems
• Signal selection circuits
• Logic function generation

Procurement Notes

Verify the manufacturer origin, as Harris Corporation assets were acquired by Rochester Electronics. Confirm the specific suffix 'E' denotes the PDIP-16 package variant. Check RoHS compliance status, as older Harris components may not meet current environmental standards. Ensure the source provides valid traceability documentation for vintage semiconductor parts.

Selection Notes

Select this component when dual 4-to-1 multiplexing is required with HC-compatible logic levels. The HCT series ensures compatibility with standard TTL inputs while maintaining CMOS output characteristics. Consider the PDIP-16 package for through-hole mounting requirements. Verify that the 51 ns propagation delay meets the system timing constraints.

Part Context

This part belongs to the CD74HCTxxxE family of high-speed CMOS logic devices originally produced by Harris Corporation. The CD74HCT153 specifically implements dual 4-input multiplexers. Following corporate acquisitions, production and distribution rights for these legacy parts are managed by Rochester Electronics LLC, which supplies reconditioned or original stock.

FAQ

What is the difference between CD74HC153 and CD74HCT153?

The primary difference lies in the input logic thresholds. The HCT series is designed to be compatible with TTL logic levels, whereas the HC series uses CMOS thresholds.

Does the CD74HCT153E have complementary outputs?

No, the CD74HCT153E provides only true outputs. Complementary outputs are found in other variants like the CD74HC151 or specific multiplexer designs.
