CD40105BK3

FIFOs Memory Overview

The CD40105BK3 is an asynchronous FIFO memory component manufactured by Harris Corporation. It features a 16 x 4 bit configuration, providing unidirectional data buffering capabilities with an 8MHz data rate. The device utilizes CMOS technology and operates within a voltage range of 5V to 15V. It is housed in a 16-lead ceramic flatpack (CDFP16) package, designed for high-temperature environments ranging from -55°C to 125°C.

FIFOs Memory Feature Summary

• Asynchronous operation with independent read and write clock domains
• Unidirectional data buffering architecture
• CMOS logic family compatibility

FIFOs Memory Applications

• Asynchronous memory buffering
• Data rate conversion interfaces
• Digital signal processing systems

FIFOs Memory Procurement Notes

Verify the manufacturer origin, as Harris Corporation's semiconductor assets were acquired. Confirm the specific package variant matches the CDFP16 ceramic flatpack requirement. Ensure the asynchronous FIFO specification aligns with system timing needs. Check for RoHS compliance status if required by current assembly standards.

FIFOs Memory Selection Notes

Select this component when independent clock domain isolation is required between source and destination circuits. The 16x4 depth suits moderate buffering needs without complex control logic. Consider the wide operating temperature range for industrial or military applications. Verify voltage levels match the 5V to 15V supply capability.

FIFOs Memory Part Context

This part belongs to the Harris Corporation logic IC portfolio, specifically within the FIFO memory category. It represents a specialized buffer solution distinct from standard shift registers or static RAM. The ceramic packaging indicates suitability for harsh environmental conditions compared to plastic equivalents.

FIFOs Memory Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires verifying pinout compatibility and electrical specifications against alternative asynchronous FIFO devices.
