CD40194BE

Shift Registers Overview

The CD40194BE is a CMOS logic integrated circuit belonging to the 4000/14000/40000 series. It functions as a 4-bit bidirectional universal shift register with parallel-in and parallel-out capabilities. The device features true outputs and operates within a supply voltage range of 3V to 18V. It supports a maximum operating frequency of 3MHz at nominal supply conditions. The component is housed in a 16-pin plastic dual in-line package (PDIP) and is rated for an extended industrial temperature range from -55°C to +125°C.

Shift Registers Feature Summary

• Supports bidirectional shifting operations controlled by mode selection inputs.

Shift Registers Applications

• Data storage and transfer systems requiring serial-to-parallel conversion.

Shift Registers Procurement Notes

Verify the specific manufacturer origin, as Harris Corporation assets were acquired by Texas Instruments. Confirm that the PDIP16 package matches the design requirements. Ensure the RoHS compliance status aligns with current environmental regulations, noting that older Harris-branded units may not meet modern standards. Validate the pinout configuration against the official datasheet before integration.

Shift Registers Selection Notes

Select this component when a bidirectional shift register with parallel loading is required. It is suitable for applications needing data movement in both directions. Consider the wide supply voltage range for flexibility in power systems. Verify the package type availability if surface mount alternatives are preferred.

Shift Registers Part Context

This part belongs to the standard 4000-series CMOS logic family, known for high noise immunity and low power consumption. It serves as a fundamental building block for digital sequential logic circuits. The device provides versatile data handling capabilities compared to unidirectional registers.

Shift Registers Replacement Considerations

Texas Instruments CD40194B or CD40194BPW are verified functional equivalents. These parts maintain identical logical functionality and pin configurations. Verify package compatibility when substituting DIP with TSSOP variants.
