MC14517BDWR2

Shift Registers Overview

The MC14517BDWR2 is a dual 64-bit static shift register from the 4000B CMOS logic series, manufactured by onsemi. It features serial-to-parallel conversion capabilities with tri-state outputs. The device operates within a supply voltage range of 3V to 18V and supports a wide operating temperature range from -55°C to 125°C. Packaged in a 16-SOIC surface-mount case, it contains two independent shift register elements. This specific part number is obsolete and no longer in production.

Shift Registers Feature Summary

• Dual 64-bit shift register architecture for serial-to-parallel data conversion
• Tri-state output capability for bus line driving applications
• Wide supply voltage operation compatible with standard CMOS logic levels

Shift Registers Applications

• Serial data acquisition systems requiring parallel output buffering
• Industrial control interfaces utilizing high-voltage CMOS logic
• Data storage and transfer circuits in harsh environmental conditions

Shift Registers Procurement Notes

This component is officially obsolete and no longer manufactured by onsemi. Procurement must rely on existing stock or authorized distributors holding legacy inventory. Verification of authenticity is critical due to potential surplus market availability. Buyers should confirm the exact revision and physical condition of units prior to purchase, as lead times are variable and not guaranteed by the manufacturer.

Shift Registers Selection Notes

Designers requiring this functionality should consider the RoHS-compliant replacement MC14517BDWR2G. The original MC14517BDWR2 lacks RoHS compliance, which may restrict use in regulated markets. Ensure that the transition to the 'G' suffix variant does not require changes to existing PCB footprints or assembly processes, as the pinout remains identical but environmental certifications differ significantly.

Shift Registers Part Context

Part of the MC14517B family within the broader 4000B CMOS logic portfolio. It serves as a high-density shift register solution for applications needing extensive bit shifting without external clocking complexity. The 16-SOIC package provides a compact form factor suitable for space-constrained industrial and commercial electronic designs requiring reliable serial data handling.

Shift Registers Replacement Considerations

The direct substitute is MC14517BDWR2G. Verify RoHS compliance requirements before substitution, as the original is non-compliant.
