CD4021BMT

Shift Registers Overview

The CD4021BMT is an 8-stage static shift register manufactured by Texas Instruments, belonging to the CD4000B CMOS logic series. It features a serial-to-serial/parallel output configuration and operates within a supply voltage range of 3 V to 18 V. The device supports a wide operating temperature range from -55 °C to +125 °C and utilizes a surface-mount SOIC-16 package.

Shift Registers Feature Summary

• Provides eight-bit data storage with parallel output capability for simultaneous data access
• Supports serial input shifting operations controlled by clock signals
• Operates reliably across industrial temperature extremes without performance degradation

Shift Registers Applications

• Digital data acquisition systems requiring serial-to-parallel conversion
• Microcontroller interface circuits for expanding I/O capabilities
• Status monitoring in industrial control panels

Shift Registers Procurement Notes

Verify the specific suffix 'MT' against official Texas Instruments documentation to confirm exact packaging and tape-and-reel specifications. Ensure compatibility with standard SOIC-16 footprints during PCB layout. Confirm RoHS compliance status through current manufacturer declarations before final procurement decisions.

Shift Registers Selection Notes

Select this component when eight-bit parallel output is required from a serial source within the CD4000B family. Consider the wide voltage tolerance for varying power environments. Evaluate thermal requirements against the specified -55 °C to +125 °C operational range for harsh conditions.
