CD4015BMT

Shift Registers Overview

The CD4015BMT is a dual 4-bit static shift register from the Texas Instruments 4000B series. It features two independent serial-in parallel-out shift registers within a single 16-pin SOIC package. The device operates on CMOS technology with a supply voltage range of 3V to 18V and supports clock frequencies up to 14 MHz at 15V. It includes individual clock and clear inputs for each register, enabling precise control over data shifting operations in digital logic circuits.

Shift Registers Feature Summary

• Dual independent 4-bit shift registers with serial input and parallel output capabilities
• Individual clock and clear inputs allow separate control of each shift register stage
• CMOS construction ensures low power consumption and high noise immunity
• Push-pull outputs provide strong drive capability for connected loads

Shift Registers Applications

• Data storage and buffering in digital systems
• Serial-to-parallel data conversion interfaces
• Sequence generation and timing control circuits
• Display driver multiplexing applications

Shift Registers Procurement Notes

Verify the exact suffix 'MT' against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with system voltage requirements within the specified operating range. Check for RoHS compliance status if required by project specifications. Confirm availability through authorized distributors as part numbers may have lifecycle changes.

Shift Registers Selection Notes

Select this component when dual independent shift registers are needed in a compact surface-mount package. Consider the 4000B series characteristics for general-purpose logic applications requiring wide voltage operation. Evaluate pin count and package size constraints against alternative solutions. Verify that the push-pull output configuration meets the load requirements of the destination circuitry.

Shift Registers Part Context

The CD4015B belongs to the standard 4000B CMOS logic family, widely used in industrial and consumer electronics. This specific variant integrates two complete 4-bit shift registers, offering design flexibility for complex data handling tasks. The SOIC-16 package facilitates automated assembly and space-efficient PCB layouts compared to through-hole alternatives.
