MC14014BD

Shift Registers Overview

The MC14014BDG is an 8-bit static shift register from the 4000B CMOS logic series, manufactured by onsemi. It features synchronous parallel input and serial output capabilities within a single monolithic structure of P-channel and N-channel enhancement mode devices. The device operates with a supply voltage range of 3.0 Vdc to 18 Vdc and supports ambient temperatures from -55°C to +125°C. It provides full static operation and includes double diode input protection. Outputs are available from the sixth, seventh, and eighth stages, allowing for flexible data tapping.

Shift Registers Feature Summary

• Synchronous parallel loading and serial shifting operations
• Full static operation ensuring stable data retention
• Outputs accessible from intermediate stages (Q6, Q7, Q8)
• Double diode input protection against high static voltages

Shift Registers Applications

• Parallel-to-serial data conversion
• Synchronous and asynchronous parallel input data queueing
• General-purpose register applications requiring low power consumption
• Applications demanding high noise immunity

Shift Registers Procurement Notes

Verify the specific suffix 'DG' corresponds to the SOIC-16 package configuration as listed in the ordering information. Confirm that the component meets RoHS compliance standards if required for your assembly process. Ensure that unused inputs are tied to appropriate logic levels during implementation to maintain circuit stability.

Shift Registers Selection Notes

Select this component when synchronous parallel loading is required alongside serial output functionality. It serves as a pin-for-pin replacement for the CD4014B. Consider this part for designs needing access to intermediate stage outputs without additional external logic. Verify that the operating voltage remains within the specified 3V to 18V range for optimal performance.

Shift Registers Part Context

This device belongs to the MC14014B/MC14021B family of 8-bit static shift registers. While the MC14021B offers asynchronous parallel input, the MC14014B specifically provides synchronous parallel input. Both share similar construction and electrical characteristics but differ in their parallel load timing relative to the clock signal.

Shift Registers Replacement Considerations

The datasheet explicitly identifies the MC14014BD as a pin-for-pin replacement for the CD4014B.
