CD74HC195NSR

Shift Registers Overview

The CD74HC195NSR is a high-speed CMOS 4-bit parallel-access shift register manufactured by Texas Instruments. It operates within a supply voltage range of 2.0 V to 6.0 V and supports serial/parallel to serial/parallel data transfer modes. The device features an asynchronous reset, positive-edge clock triggering, and complementary serial outputs. It is housed in a 16-pin SOIC package with a maximum operating temperature of +125 °C and a minimum of -55 °C.

Shift Registers Feature Summary

• Supports both serial and parallel input/output configurations for flexible data handling.
• Includes an asynchronous clear function to instantly reset the register state.
• Utilizes high-speed CMOS technology for efficient power consumption and performance.

Shift Registers Applications

• Data storage and buffering in digital logic circuits
• Serial-to-parallel conversion tasks
• Parallel-to-serial conversion applications

Shift Registers Procurement Notes

Verify the specific suffix 'SR' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation or component markings. Ensure the selected variant matches the required operating temperature range and voltage specifications for the target application environment.

Shift Registers Selection Notes

Select this component for designs requiring 4-bit shift register functionality with parallel access capabilities. Consider the HC logic series for compatibility with standard CMOS interfaces. Evaluate the SOIC-16 package constraints against available PCB space and thermal management requirements.

Shift Registers Part Context

This part belongs to the CD74HC195 family of 4-bit parallel-access shift registers. It shares functional similarities with other members like the SN74HC195 but differs in packaging and manufacturing revisions. The HC series denotes high-speed CMOS technology, offering improved speed over legacy LS variants while maintaining low power dissipation characteristics typical of CMOS logic families.

Shift Registers Replacement Considerations

Direct substitutes include CD74HC195M96 and SN74HC195N. Verify pinout compatibility and electrical parameters before substitution.
