74HC9115N,112

Overview

The NXP USA Inc. 74HC9115N,112 is a nine-wide Schmitt trigger buffer featuring open-drain outputs and inverting logic functionality. Manufactured using high-speed CMOS technology within the HC/UH series, this component utilizes a PDIP-20 package for through-hole mounting. It operates across a temperature range of -40 °C to +85 °C with a load capacitance of 50 pF. The device incorporates Schmitt trigger inputs to ensure noise immunity and stable switching performance.

Feature Summary

• Features nine independent wide Schmitt trigger buffers for enhanced signal integrity
• Provides open-drain output configuration suitable for wired-OR applications
• Incorporates inverting logic functionality within a single integrated circuit

Applications

• Digital signal buffering in noisy environments requiring hysteresis
• Interface circuits utilizing open-drain logic levels
• Pulse shaping and waveform conditioning for digital systems

Procurement Notes

Verify the specific ordering code suffix against official NXP documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with industrial temperature ranges if operating conditions exceed standard commercial limits. Cross-reference pinout diagrams with target PCB layouts to prevent installation errors due to package variations.

Selection Notes

Select this component when multiple buffered channels are required in a compact DIP package. The open-drain architecture allows for flexible voltage level shifting compared to standard push-pull outputs. Consider the propagation delay characteristics relative to system clock speeds to ensure timing requirements are met during high-frequency operation.

Part Context

This part belongs to the NXP 74HC family of high-speed CMOS logic devices. These components are designed to replace older TTL logic families while offering lower power consumption and higher noise margins. The HC series is widely used in general-purpose digital electronics, microcontroller interfaces, and memory systems.

Replacement Considerations

Check for direct cross-reference equivalents such as the MC74HC9115 from ON Semiconductor or generic 74HC9115 variants from other manufacturers. Verify that substitute parts maintain identical pin configurations and electrical characteristics to ensure seamless integration without hardware modifications.
