SN74HC266DRG4

Inverter Gates Overview

The SN74HC266DRG4 is a single-function logic gate integrated circuit manufactured by Texas Instruments. It implements four independent XNOR (exclusive-NOR) gates, each with two inputs. The device operates within a supply voltage range of 2 V to 6 V and features open-drain outputs capable of sourcing or sinking up to 5.2 mA. It utilizes CMOS technology and is housed in a 14-pin SOIC package. The component supports surface-mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Inverter Gates Feature Summary

• Contains four independent two-input XNOR logic gates
• Features open-drain output configuration for flexible interfacing
• Operates on a wide supply voltage range from 2 V to 6 V
• Utilizes high-speed CMOS technology for low power consumption

Inverter Gates Applications

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

Inverter Gates Procurement Notes

Verify the specific ordering suffix DRG4 to confirm the tape-and-reel packaging format and lead-free RoHS compliance status. Ensure the selected variant matches the required SOIC-14 footprint and thermal characteristics for the target application environment. Cross-reference the manufacturer datasheet for any recent product change notifications affecting pinout or electrical specifications before finalizing procurement.

Inverter Gates Selection Notes

Select this component when a quad XNOR function with open-drain outputs is required within the 74HC family. The open-drain nature allows for wired-AND connections and level shifting if necessary. Compare propagation delay and output current capabilities against other logic families if higher speed or push-pull outputs are needed. Ensure the 2V to 6V supply range aligns with the system power rails.

Inverter Gates Part Context

This part belongs to the SN74HC series of high-speed CMOS logic devices produced by Texas Instruments. The HC series is designed to offer performance comparable to the older LS-TTL standard while maintaining lower power consumption. The SN74HC266 specifically provides XNOR functionality, distinguishing it from standard NAND or NOR variants within the same logical package constraints.

Inverter Gates Replacement Considerations

The SN74HC266D is a direct equivalent without the G4 suffix, offering identical electrical characteristics but potentially different packaging or environmental compliance details. Verify that any substitute maintains the open-drain output structure and SOIC-14 package dimensions to ensure mechanical and functional compatibility.
