CD54HCT299F

Shift Registers Overview

The CD54HCT299F is an 8-bit bidirectional shift register manufactured by Harris Corporation. It utilizes HCT-CMOS technology and operates at a maximum frequency of 16 MHz under nominal supply conditions. The device features a ceramic DIP-20 package with a rectangular inline form factor. It supports a supply voltage of 5 V and functions within a temperature range of -55 °C to 125 °C, meeting military temperature standards.

Shift Registers Feature Summary

• Bidirectional serial shifting capability for data transmission
• Parallel input and parallel output access modes
• Totem-pole outputs for direct drive applications

Shift Registers Applications

• High-speed serial-to-parallel conversion
• Parallel-to-serial data transmission
• Digital signal processing interfaces

Shift Registers Procurement Notes

Verify the component's RoHS compliance status, as it is marked non-compliant in available records. Confirm the manufacturer origin, noting potential production by Harris Corporation or subsequent licensees like Renesas. Ensure the ceramic DIP-20 package matches the specific application requirements for thermal and mechanical stability.

Shift Registers Selection Notes

Select this component when a robust, high-speed shift register is required for harsh environments. The HCT logic family ensures compatibility with standard TTL inputs while maintaining CMOS power efficiency. The military-grade temperature rating makes it suitable for aerospace and defense applications where reliability is critical.

Shift Registers Part Context

This part belongs to the CD54 series of logic integrated circuits, designed for military specifications. It is functionally related to other shift registers in the HCT family but distinguished by its specific packaging and radiation-hardened characteristics typical of the CD54 line. It serves as a core component in digital systems requiring reliable data storage and transfer.

Shift Registers Replacement Considerations

Check for equivalents from Renesas, which acquired Harris Semiconductor's logic assets. Verify pinout compatibility with other 8-bit bidirectional shift registers in the 74HCT series if package constraints allow.
