74HCT9115N,112

Overview

The NXP USA Inc. 74HCT9115N,112 is a nine-wide Schmitt trigger buffer featuring open-drain outputs and input clamp diodes. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device complies with JEDEC standards JESD8C (2.7 V to 3.6 V) and JESD7A (2.0 V to 6.0 V). Propagation delay ranges from 10 ns to 165 ns depending on voltage and temperature. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Schmitt trigger action on all data inputs transforms slowly changing signals into sharply defined jitter-free output signals.
• Open drain outputs allow flexible interfacing and voltage level shifting capabilities.
• Input clamp diodes enable the use of current limiting resistors for interfacing to voltages exceeding VCC.

Applications

• Signal buffering in high-noise environments requiring jitter-free transitions.
• Voltage level translation between different logic families using open-drain configuration.
• Interface circuits where inputs may exceed the supply voltage via current limiting resistors.

Procurement Notes

Verify that the ordering suffix ',112' corresponds to the specific tape-and-reel packaging variant required for automated assembly processes. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing standards. Ensure the selected package type aligns with your PCB footprint design constraints before finalizing procurement orders.

Selection Notes

Select this component when nine buffered channels with Schmitt trigger hysteresis are required. The open-drain output structure is suitable for wired-OR configurations or driving loads at voltages higher than the logic supply. Verify that the propagation delay specifications meet the timing requirements of your specific application circuit under expected operating temperatures.

Part Context

This part belongs to the 74HC/HCT logic family, designed for high-speed CMOS applications. It serves as a wide buffer solution, consolidating multiple single-channel buffers into a single integrated circuit. The device is manufactured by Nexperia, continuing the legacy of NXP Semiconductors logic products, providing pin compatibility with standard TTL and CMOS interfaces.

Replacement Considerations

The datasheet revision history indicates that type numbers 74HC9115N and 74HCT9115N were removed from the document. Verify functional equivalence with other nine-wide Schmitt trigger buffers if exact substitution is needed, ensuring open-drain output characteristics match the original design intent.
