CD4517BF3A

Shift Registers Overview

The CD4517BF3A is a dual 64-stage static shift register from the Texas Instruments 4000/14000/40000 series. It features serial-to-parallel conversion capabilities with true outputs and operates within a supply voltage range of 3 V to 18 V. The device utilizes CMOS logic technology and provides three-state outputs for bus connection compatibility. It is housed in a 16-pin ceramic dual in-line package (CDIP) and supports an operating temperature range from -55 °C to +125 °C.

Shift Registers Feature Summary

• Dual independent 64-stage static shift registers
• Three-state parallel outputs for common bus interfacing
• CMOS logic construction for low power consumption

Shift Registers Applications

• Military and defense applications requiring QML certification
• Serial-to-parallel data conversion systems
• High-reliability industrial control circuits

Shift Registers Procurement Notes

Verify RoHS compliance status, as this specific variant is listed as non-compliant in official documentation. Confirm availability status, which may be designated as Not Recommended for New Designs (NRND). Ensure procurement channels can source ceramic packages and validate lead finish specifications prior to ordering.

Shift Registers Selection Notes

Select this component when military-grade reliability or extended temperature operation is required. The ceramic package offers superior environmental resistance compared to plastic variants. Verify that the application requires three-state outputs and compatible voltage levels between 3 V and 18 V before finalizing the design.

Shift Registers Part Context

This part belongs to the CD4517B family, specifically the military-qualified version. It shares functional characteristics with catalog versions but differs in packaging and qualification standards. The 'F3A' suffix denotes the specific ceramic package and material configuration provided by Texas Instruments.

Shift Registers Replacement Considerations

Qualified substitutes include other military-qualified dual 64-stage shift registers from the same family. Verify pinout compatibility and electrical specifications against the original datasheet requirements before substitution.
