CD74HC40105EX

FIFOs Memory Overview

The CD74HC40105EX is a high-speed CMOS shift register manufactured by Harris Corporation, belonging to the HC/UH logic series. It features a 4-bit serial-in parallel-out architecture housed in a 16-pin PDIP package. The device operates with a supply voltage range of 2V to 6V and supports a maximum clock frequency of 35 MHz at nominal supply conditions. It functions as a synchronous positive-edge triggered circuit with an asynchronous reset input that clears all stages to zero. The component is rated for operation across an extended temperature range from -55°C to 125°C.

FIFOs Memory Feature Summary

• Synchronous data shifting capability controlled by a single clock input
• Asynchronous reset function to clear internal storage states immediately
• High noise immunity characteristics inherent to CMOS technology

FIFOs Memory Applications

• Serial-to-parallel data conversion circuits
• Parallel-to-serial data transmission interfaces
• Digital timing sequence generation systems

FIFOs Memory Procurement Notes

Verify the manufacturer origin carefully, as Texas Instruments acquired Harris Semiconductor's logic product lines. Confirm the specific suffix 'EX' corresponds to the intended packaging and material specifications. Ensure compatibility with existing board layouts requiring 16-pin DIP footprints. Check RoHS compliance status against current regulatory requirements for the target market.

FIFOs Memory Selection Notes

Select this component when a compact 4-bit shift solution is required within standard 74HC logic families. Consider the 35 MHz speed limit for high-frequency applications. Evaluate the PDIP20 footprint availability if alternative pin counts are acceptable. Compare power consumption metrics against other logic families if energy efficiency is critical for the design.

FIFOs Memory Part Context

This part belongs to the widely adopted 74HC family of digital logic integrated circuits. These components serve as fundamental building blocks for sequential logic operations in various electronic systems. The HC designation indicates High-speed CMOS technology, offering performance comparable to TTL while maintaining lower power dissipation. This specific model provides basic shift register functionality without complex decoding or counting features.
