CD74HC40105E

Overview

The CD74HC40105E is a synchronous shift register belonging to the HC/UH series, manufactured by Harris Corporation. It features four independent 4-bit shift registers with serial input and parallel output capabilities. The device operates on a positive edge-triggered mechanism and utilizes CMOS technology. It supports a supply voltage range of 2V to 6V and functions within an industrial temperature range of -55°C to +125°C. The component is housed in a 16-pin DIP package.

Feature Summary

• Synchronous operation triggered by positive clock edges
• Four independent 4-bit shift register channels
• CMOS logic family compatibility for low power consumption

Applications

• Serial-to-parallel data conversion circuits
• Parallel-to-serial data transmission systems
• Digital signal processing delay lines

Procurement Notes

Verify the manufacturer designation carefully, as Texas Instruments acquired Harris Semiconductor's logic product line. Confirm that the specific part number corresponds to the original Harris manufacturing specifications rather than subsequent TI revisions. Ensure the package type matches the required 16-pin DIP configuration for your design constraints.

Selection Notes

Select this component when multiple independent 4-bit shift operations are required within a single integrated circuit. The HC series offers standard CMOS performance suitable for general-purpose digital logic applications. Consider the operating voltage range and temperature specifications to ensure compatibility with the target system environment.

Part Context

This component is part of the broader 74HC logic family, which provides high-speed CMOS operation compatible with standard TTL logic levels. The CD74HC40105E specifically addresses the need for compact shift register solutions in digital systems requiring data serialization or deserialization tasks.
