T74LS266B1 Description

Short technical summary and product information.

The STMicroelectronics T74LS266B1 is a versatile integrated circuit featuring four independent 2-input exclusive NOR gates. Each gate is designed for reliable operation and offers open collector outputs, providing flexibility in circuit design.

 

This component is housed in a standard 14-pin Dual In-line Package (DIP), making it suitable for through-hole mounting and breadboarding. The T74LS266B1 is part of the 74LS logic family, known for its balance of speed and power consumption.

 

Key electrical characteristics include its function as an exclusive NOR gate, with four such gates integrated into a single chip. The open collector output requires a pull-up resistor for proper operation when interfacing with other logic families or driving loads. This device is suitable for various digital logic applications where NOR functionality is required.

 

Designed for general-purpose digital logic applications, the T74LS266B1 can be used in control circuits, data selectors, and other digital systems. Its DIP package facilitates ease of use in prototyping and production environments.
