MC14014BDR2G

Shift Registers Overview

The MC14014BDR2G is an 8-bit static shift register from the MC14014B series, manufactured by onsemi. It features synchronous parallel input and serial output capabilities within a single monolithic MOS structure. The device operates over a supply voltage range of 3.0 Vdc to 18 Vdc and supports ambient temperatures from -55°C to +125°C. It includes double diode input protection and provides Q outputs from the sixth, seventh, and eighth stages. The component is housed in a SOIC-16 package and is Pb-Free and RoHS compliant.

Shift Registers Feature Summary

• Synchronous parallel-to-serial data conversion with dedicated control inputs
• External access to internal stage outputs for intermediate data monitoring
• Robust input protection against high static voltages and electric fields
• Capable of driving low-power TTL or low-power Schottky TTL loads

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging configuration, as standard bulk quantities may vary. Ensure the procurement documentation explicitly states RoHS compliance and Pb-Free status to meet environmental regulations. Confirm that the supplier source matches the official onsemi manufacturing site requirements if automotive qualification (NLV prefix) is not required for this specific non-automotive part number.

Shift Registers Selection Notes

Select this component when synchronous parallel loading and serial shifting are required within a single IC. It serves as a pin-for-pin replacement for the CD4014B, facilitating direct upgrades or cross-manufacturer sourcing. Consider the wide operating voltage range and temperature stability for industrial environments. Verify that the load capacitance requirements align with the specified propagation delay characteristics for the target clock frequency.

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 functionality. Both share identical pinouts and core architecture, differing primarily in the timing relationship between the parallel load signal and the clock edge. This family is designed for general-purpose logic applications using standard CMOS technology.

Shift Registers Replacement Considerations

The MC14014BDR2G is documented as a pin-for-pin replacement for the CD4014B. Designers should verify electrical parameter compatibility, particularly regarding drive current and propagation delays, when substituting across different manufacturers. No other direct substitute part numbers are listed in the provided datasheet.
