HCF4021M013TR

Shift Registers Overview

The HCF4021M013TR is an 8-stage static shift register from the STMicroelectronics HCF4000B series, fabricated using metal oxide semiconductor technology. It operates within a supply voltage range of 3 V to 20 V and features parallel-to-serial data conversion capabilities. The device utilizes a SOIC-16 surface-mount package and supports synchronous serial entry alongside asynchronous parallel input. It includes buffered outputs and is qualified for automotive applications under AEC-Q100 standards, ensuring reliability across an operating temperature range of -40°C to +125°C.

Shift Registers Feature Summary

• Supports both synchronous serial shifting and asynchronous parallel loading of data into eight D-type master-slave flip-flops.
• Provides buffered serial output along with individual access to internal stage outputs for expanded monitoring or control.
• Complies with AEC-Q100 automotive qualification standards for enhanced durability in vehicle electronics environments.

Shift Registers Applications

• Automotive body control modules requiring reliable data storage and transfer
• Industrial systems utilizing parallel-to-serial data conversion interfaces
• Embedded controllers needing extended I/O expansion through cascading registers

Shift Registers Procurement Notes

Verify the specific suffix M013TR against official STMicroelectronics documentation to confirm package type and reel specifications. Ensure compatibility with AEC-Q100 requirements if deploying in automotive contexts. Cross-reference the SOIC-16 footprint dimensions during PCB layout to prevent assembly errors. Confirm moisture sensitivity handling procedures are followed upon receipt to maintain component integrity.

Shift Registers Selection Notes

Select this component when an 8-bit parallel-to-serial converter is required within the HCF logic family. It is suitable for designs needing robust performance across wide voltage and temperature ranges. Consider its automotive qualification status for applications demanding higher reliability standards compared to standard commercial grade logic devices.

Shift Registers Part Context

This part belongs to the HCF4000B series of high-speed CMOS logic integrated circuits manufactured by STMicroelectronics.
