CD54HC4094F3A

Shift Registers Overview

The CD54HC4094F3A is an 8-bit serial-in, parallel-out shift register manufactured by Harris Corporation. It belongs to the HC/UH CMOS logic series and features true outputs. The device is housed in a 16-lead ceramic dual in-line package (CDIP) with metal-sealed cofired construction. It operates within a supply voltage range of 2 V to 6 V and supports a wide temperature range from -55°C to 125°C, suitable for military applications.

Shift Registers Feature Summary

• Provides 8-bit serial-to-parallel data conversion capability
• Features true output polarity for direct logic interfacing
• Constructed with ceramic metal-sealed cofired packaging for environmental robustness

Shift Registers Applications

• Military-grade digital signal processing systems
• Industrial control equipment requiring extended temperature operation
• Data acquisition systems utilizing serial communication interfaces

Shift Registers Procurement Notes

Verify the specific manufacturer source, as Harris Corporation's semiconductor assets were acquired. Confirm that the component meets current military qualification standards if required for your application. Ensure the ceramic package integrity matches original specifications for high-reliability environments. Check for RoHS compliance status, noting that older military parts may not adhere to modern environmental directives.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with true outputs is required in a hermetically sealed ceramic package. It is appropriate for designs needing operation across extreme temperatures from -55°C to 125°C. Consider the HC/UH series compatibility for logic level interfacing within the 2 V to 6 V supply range. This part is distinct from plastic-packaged variants due to its radiation and moisture resistance.

Shift Registers Part Context

This component is part of the CD54HCxx series, which denotes military-grade performance using HC/UH technology. The 'F3' suffix typically indicates the specific ceramic DIP package variant produced by Harris. It serves as a replacement for legacy military shift registers requiring high reliability and wide thermal stability in aerospace or defense electronics.

Shift Registers Replacement Considerations

Direct substitutes include other military-grade 8-bit shift registers in CDIP packages, such as those from Texas Instruments or Analog Devices, provided they match the HC/UH logic family and pinout. Verify equivalent propagation delay and output drive characteristics. Plastic equivalents like the SN74HC595 do not offer the same environmental sealing.
