SN74HC266NSR

Inverter Gates Overview

The SN74HC266NSR is a CMOS logic integrated circuit manufactured by Texas Instruments, featuring four independent XNOR gates within a single package. It operates on a supply voltage range of 2V to 6V and utilizes a 14-pin SOIC surface-mount package. The device provides push-pull outputs with a maximum low-level output current of 5.2mA and a high-level output current of -5.2mA. Propagation delay varies based on load capacitance and voltage, reaching up to 23ns at 6V with 50pF load. It supports an operating temperature range from -40°C to +85°C.

Inverter Gates Feature Summary

• Contains four independent exclusive-NOR (XNOR) logic functions
• Features open-drain output configuration for flexible interfacing
• CMOS technology ensures low quiescent current consumption
• Supports wide supply voltage operation from 2V to 6V

Inverter Gates Applications

• Parity generation and checking systems
• Error detection logic in communication interfaces
• Boolean function implementation in control logic

Inverter Gates Procurement Notes

Verify the specific suffix 'NSR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the open-drain output characteristic aligns with the pull-up resistor requirements of the target application circuit. Ensure the SOIC-14 footprint matches the PCB design constraints and thermal management specifications for the intended operating environment.

Inverter Gates Selection Notes

Select this component when an XNOR function with open-drain outputs is required in a space-constrained surface-mount design. The HC series offers compatibility with standard 5V logic levels while supporting lower voltage operations down to 2V. Consider the propagation delay specifications relative to the system clock speed to ensure timing margins are met under worst-case load conditions.

Inverter Gates Part Context

This part belongs to the SN74HC family of high-speed CMOS logic devices produced by Texas Instruments. The HC series is designed for general-purpose digital applications requiring fast switching speeds and low power consumption. The SN74HC266 specifically provides XNOR functionality, distinguishing it from standard NAND or NOR variants within the same logical family and pinout architecture.

Inverter Gates Replacement Considerations

Compatible substitutes include the SN74HCS266NSR for automotive-grade applications and the SN74HC266N for through-hole DIP packaging. Verify that alternative manufacturers offer equivalent open-drain output characteristics and compatible voltage ranges before substitution.
