SN74HC266D Description

Short technical summary and product information.

The SN74HC266D from Texas Instruments is a high-speed quadruple 2-input XNOR gate integrated circuit. Each gate within the device performs the Boolean function Y = A ⊕ B in positive logic and features open-drain outputs. This allows for flexible output configurations and interfacing with different logic levels.

The device operates across a wide voltage range of 2V to 6V, making it suitable for diverse electronic designs. It offers a drive strength of 5.2 mA (IOL) and a maximum propagation delay of 23 ns at 6V with a 50pF load capacitance. The operating temperature range is from -40°C to 85°C, ensuring reliable performance in various environmental conditions.

Packaged in a 14-SOIC (0.154", 3.90mm Width) surface-mount case, the SN74HC266D is designed for standard PCB assembly. Its open-drain output capability can be utilized for wired-AND logic functions when connected through a common pull-up resistor. This component is part of the HC (High-speed CMOS) technology family, offering a balance of speed and low power consumption.
