CD74HC195PWT

Shift Registers Overview

The CD74HC195PWT is a high-speed CMOS 4-bit parallel access shift register manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and supports serial/parallel-to-serial/parallel data transfer modes. The device features asynchronous reset functionality and rising-edge clock triggering. It is housed in a 16-pin TSSOP surface-mount package, designed for operation across an extended temperature range from -55°C to +125°C.

Shift Registers Feature Summary

• Supports bidirectional data loading via simultaneous serial and parallel inputs
• Provides independent Q0 through Q3 outputs for direct parallel access
• Includes asynchronous reset input for immediate clearing of all stages

Shift Registers Applications

• Data storage and buffering in digital logic circuits
• Serial-to-parallel conversion for display drivers
• Parallel-to-serial conversion for communication interfaces

Shift Registers Procurement Notes

Verify the specific suffix 'PWT' against the official Texas Instruments datasheet to confirm the TSSOP-16 package and tape-and-reel packaging configuration. Ensure compatibility with system voltage levels between 2V and 6V. Confirm that the operating temperature range meets environmental requirements before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when a 4-bit shift register with parallel output capability is required in a compact surface-mount form factor. The HC series offers standard CMOS performance suitable for general-purpose logic applications. Consider the TSSOP package dimensions for PCB layout constraints and verify pinout alignment with existing schematic designs.

Shift Registers Part Context

This part belongs to the Texas Instruments CD74HC195 family of 4-bit shift registers. It shares functional similarities with other variants such as the CD74HC195M96 (SOIC) and CD74HC195NSR (SOIC), differing primarily in package type and reel specifications. All variants maintain identical logical operations and electrical characteristics defined by the 74HC series standards.

Shift Registers Replacement Considerations

Compatible substitutes include CD74HC195M96 and CD74HC195NSR. Verify package footprint compatibility when replacing the TSSOP variant with SOIC versions.
