HCF4555M013TR

Overview

The HCF4555M013TR is a dual binary to 1-of-4 decoder/demultiplexer fabricated in Metal Oxide Semiconductor technology. It features two independent decoders, each with two select inputs (A and B), an active-high enable input (E), and four mutually exclusive outputs that are high on select. The device operates within a supply voltage range of 3V to 20V and supports an operating temperature range from -55°C to +125°C. Propagation delay varies by voltage: at 5V it ranges from 220ns to 440ns, while at 15V it decreases to 70ns–140ns.

Feature Summary

• Dual architecture providing two independent 1-of-4 decoding channels within a single package
• Outputs activate high when selected, ensuring standardized symmetrical output characteristics
• Capable of expansion for higher-order decoding configurations such as 1-of-8 or 1-of-16 setups

Applications

• Data demultiplexing applications requiring 1-of-4 line distribution
• Expanding into 1-of-8 or 1-of-16 decoder systems using multiple units
• General-purpose digital logic switching and signal routing

Procurement Notes

Verify the specific suffix M013TR corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the component meets AEC-Q100 or other relevant automotive qualification standards if intended for vehicle electronics. Ensure ESD handling protocols are followed during storage and installation due to CMOS sensitivity.

Selection Notes

Select this component when a design requires two separate 1-of-4 decoding functions in a compact footprint. Consider the propagation delay specifications relative to the system clock speed at the target operating voltage. Verify that the SOIC-16 package dimensions align with the PCB layout constraints and thermal management requirements.
