SN74HC266DR

Inverter Gates Overview

The SN74HC266DR is a Texas Instruments logic gate integrated circuit featuring four XNOR gates with Schmitt-trigger inputs. It operates within a supply voltage range of 2V to 6V and utilizes an open-drain output configuration. The device is housed in a 14-SOIC surface-mount package. Key electrical characteristics include a maximum propagation delay of 23ns at 6V with a 50pF load, low static current consumption of 2µA, and drive strengths of 5.2mA for both high and low states.

Inverter Gates Feature Summary

• Four independent XNOR logic channels
• Schmitt-trigger input action for noise filtering
• Open-drain output structure
• Wide operating voltage compatibility

Inverter Gates Applications

• Digital signal processing circuits
• Data comparison logic
• Noise-immune interface design
• Level shifting applications

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'DR' confirms the SOIC-14 tape-and-reel packaging format. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm that the open-drain output architecture aligns with your system's pull-up resistor strategy and voltage level requirements before finalizing procurement.

Inverter Gates Selection Notes

Select this component when XNOR functionality combined with Schmitt-trigger noise immunity is required. The open-drain output necessitates external pull-up resistors, which allows flexibility in interfacing with different voltage domains. Verify that the 2V to 6V supply range matches your system power rails and that the 14-SOIC package fits your PCB layout constraints.

Inverter Gates Part Context

This part belongs to the SN74HC series of high-speed CMOS logic devices. It provides industry-standard pinouts and performance characteristics compatible with other HC family components. The SN74HC266 variant specifically offers XNOR logic with Schmitt triggers, distinguishing it from standard XNOR gates lacking hysteresis features.
