CD4094BD

Shift Registers Overview

The CD4094BD is an 8-bit serial-in, parallel-out shift-and-store bus register manufactured by Harris Corporation. It belongs to the 4000/14000/40000 series of CMOS logic devices and utilizes a ceramic dual in-line package (CDIP) with 16 pins. The component features true outputs and supports right-direction data shifting. It includes a strobe input for latching parallel data and an output enable control for managing three-state conditions on the parallel outputs.

Shift Registers Feature Summary

• Provides serial-to-parallel conversion with independent data storage capability via a dedicated latch function
• Integrates three-state parallel outputs controlled by an enable signal for bus sharing applications
• Constructed using radiation-hardened CMOS technology suitable for demanding environments
• Housed in a metal-sealed ceramic DIP package designed for high reliability

Shift Registers Applications

• Data acquisition systems requiring serial interface expansion
• Display drivers for multiplexed indicator panels
• Remote terminal units in aerospace or military communication equipment
• Industrial control interfaces utilizing robust logic components

Shift Registers Procurement Notes

Verify that the specific unit matches the CD4094BD designation rather than standard plastic variants like CD4094BE. Confirm the manufacturer origin as Harris Corporation or its successor entities such as Intersil or Renesas, noting that these organizations acquired the original product lines. Ensure the package material is specified as ceramic metal-sealed cofired construction, which distinguishes this part from commercial grade equivalents. Check for radiation hardening certification if the application requires it.

Shift Registers Selection Notes

Select this component when system requirements demand radiation tolerance and long-term stability provided by ceramic packaging. It serves as a direct functional replacement for other 8-bit shift registers within the 4000 series family that lack integrated latching or three-state output capabilities. Consider the physical dimensions of the CDIP16 package during PCB layout planning. Evaluate power supply constraints against the wide operating voltage range typical of CMOS logic families.

Shift Registers Part Context

This device is part of the extensive 4000 series of CMOS digital logic circuits originally developed for general-purpose computing and industrial control. Harris Corporation produced this variant specifically for markets requiring higher reliability standards than standard plastic packages offer. The CD4094BD shares logical functionality with other 8-bit shift registers but differentiates itself through its specialized packaging and environmental hardening characteristics.

Shift Registers Replacement Considerations

Substitutes include the HEF4094B from NXP Semiconductors and the MC14094B from ON Semiconductor. These alternatives provide identical logical operations but typically utilize plastic DIP packages rather than the ceramic construction of the CD4094BD. Verify pin compatibility and ensure the replacement meets the specific temperature and radiation requirements of the target application.
