CD74HC195EG4

Shift Registers Overview

The CD74HC195EG4 is a 4-bit parallel-access shift register manufactured by Texas Instruments. It belongs to the HC logic family and operates on a single supply voltage ranging from 2 V to 6 V. The device features asynchronous reset functionality and rising-edge triggered clocking for data storage. It supports serial and parallel input modes with complementary serial outputs, enabling flexible data handling in digital circuits. The component is housed in a 16-pin SOIC package designed for surface-mount installation.

Shift Registers Feature Summary

• Provides four-bit data storage with parallel access capabilities for immediate reading or writing of register states.
• Supports bidirectional data flow through serial and parallel input configurations alongside complementary serial outputs.
• Features an asynchronous reset mechanism that clears all stored data independently of the clock signal.

Shift Registers Applications

• Digital data processing systems requiring temporary storage and manipulation of binary information.
• Communication interfaces utilizing serial-to-parallel conversion for data transmission protocols.
• Control logic circuits implementing sequential operations within automated machinery.

Shift Registers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS standards during procurement. Confirm the package type matches the required PCB footprint, as variations exist between DIP and SOIC formats. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the manufacturer datasheet for exact pinout definitions to prevent integration errors.

Shift Registers Selection Notes

Select this component when a 4-bit shift register with parallel access is required within the HC logic family constraints. Consider the 2 V to 6 V supply range compatibility with existing system voltages. Evaluate the need for complementary outputs if driving differential loads. Assess the package size requirements against available board space, noting the distinction between through-hole and surface-mount options.

Shift Registers Part Context

This part is a member of the Texas Instruments 74HC series, known for high-speed CMOS operation. It serves as a fundamental building block for sequential logic designs. The device complements other logic families by offering low power consumption and noise immunity. Its design facilitates integration into complex digital systems requiring reliable data shifting and storage functions.

Shift Registers Replacement Considerations

Check for direct equivalents such as SN74HC195 variants or generic 74HC195 components from other manufacturers. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement supports the same supply voltage range and package style to maintain circuit integrity without redesign.
