74HC9115D-Q100J

Overview

The Nexperia 74HC9115D-Q100J is a nine-wide Schmitt trigger buffer with open drain outputs, qualified to AEC-Q100 Grade 1 for automotive use. It operates on a supply voltage of 2.0 V to 6.0 V and functions across temperatures from -40 °C to +125 °C. The device features Schmitt trigger inputs that convert slowly changing signals into jitter-free outputs. Propagation delay ranges from 10 ns to 165 ns depending on voltage and temperature. Input leakage current is ±0.1 μA at 25 °C, rising to ±1.0 μA at extreme temperatures.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1) standards
• Schmitt trigger action on all data inputs for noise immunity
• Open drain outputs suitable for wired-AND configurations
• Input clamp diodes allow interfacing with voltages exceeding VCC

Applications

• Automotive electronic systems requiring robust signal buffering
• Interfaces where input signals exceed the logic supply voltage
• Applications demanding high noise immunity and slow rise/fall times

Procurement Notes

Verify the specific suffix 'J' corresponds to the SO20 plastic small outline package (SOT163-1) as defined in the ordering information table. Confirm the temperature range specification matches the required operational environment of -40 °C to +125 °C. Ensure design compliance with AEC-Q100 Grade 1 requirements if used in automotive contexts. Cross-reference pin assignments against the schematic to match the 20-lead configuration.

Selection Notes

Select this component when nine buffered channels are required within a single package. The open drain output architecture necessitates external pull-up resistors for proper HIGH-level operation. Consider the propagation delay variations across the specified voltage and temperature ranges during timing analysis. Verify that the input voltage levels remain within the clamping diode limits to prevent excessive current flow.

Part Context

This part belongs to the 74HC9115-Q100 family of wide Schmitt trigger buffers. It is designed for high-noise environments and automotive applications. The device provides nine independent buffers with identical characteristics. It utilizes CMOS technology for low power dissipation while maintaining high noise immunity through Schmitt trigger input stages.

Replacement Considerations

Direct substitutes must be verified against the official Nexperia replacement list or equivalent automotive-grade nine-channel Schmitt trigger buffers with open drain outputs. Ensure any alternative maintains the same AEC-Q100 Grade 1 qualification and SO20 package dimensions.
