LD6816CX4/C27P,315

Overview

The LD6816CX4/C27P,315 is a low-power Schmitt trigger buffer manufactured by Nexperia USA Inc. It belongs to the 74AUP logic family and operates within a wide supply voltage range from 0.8 V to 3.6 V. The device features Schmitt-trigger inputs that provide tolerance for slow input rise and fall times, ensuring high noise immunity. It includes I_OFF circuitry to support partial power-down applications by disabling outputs and preventing damaging backflow currents. The component complies with JEDEC standards for various voltage ranges and offers ESD protection exceeding 5000 V (HBM) and 1000 V (CDM).

Feature Summary

• Schmitt-trigger action at inputs for tolerance of slow signal transitions.
• I_OFF circuitry enables partial power-down mode operation.
• Wide supply voltage range supporting low-power CMOS dissipation.
• High noise immunity with overvoltage tolerant inputs.

Applications

• Buffering signals in low-voltage digital systems.
• Partial power-down applications requiring backflow current prevention.
• Interfaces requiring tolerance for slow input rise and fall times.

Procurement Notes

Verify the specific suffix C27P,315 against official Nexperia documentation to confirm package type and reel specifications. Ensure compatibility with the required operating temperature range and voltage levels. Confirm RoHS compliance and halogen-free status as per manufacturer declarations. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when designing circuits that require Schmitt-trigger buffering in low-voltage environments. It is suitable for applications needing high noise immunity and protection against slow signal transitions. Consider the I_OFF feature if partial power-down functionality is necessary to prevent backflow currents. Verify that the 0.8 V to 3.6 V supply range matches the system requirements.

Part Context

This component is part of the 74AUP series, which focuses on low-power performance and wide supply voltage operation. It is designed for general-purpose buffering and signal conditioning in portable and battery-driven equipment. The AUP series is known for its high speed and low power consumption, making it ideal for modern low-voltage digital designs.

Replacement Considerations

Check for direct substitutes within the 74AUP family with compatible pinouts and electrical characteristics. Verify that any replacement maintains the Schmitt-trigger input functionality and I_OFF capability. Ensure the alternative part supports the same voltage range and ESD protection levels.
