74266 Quad 2-Input Exclusive-NOR Gates 5V 8mA DIP-14

Description

74266 Quad 2-Input Exclusive- NOR Gates 5V 8mA DIP-14 The 74266 is a quad 2-input Exclusive-NOR (XNOR) logic gate integrated circuit containing four independent gates in a single package. Each gate compares two digital input signals and produces a HIGH output when both inputs have the same logic state. The output becomes LOW when the inputs differ, making the IC useful for digital comparison and equality detection applications. This IC features open-collector outputs, which require external pull-up resistors to produce a valid HIGH logic level. The open-collector configuration also allows outputs to be connected in suitable wired logic arrangements. Supplied in a 14-pin dual in-line package (DIP-14), it is suitable for through-hole PCB assembly, digital logic experiments, educational projects, and general-purpose logic circuits. Features: Four independent 2-input XNOR gates. Performs digital equivalence logic. Open-collector output configuration. Supports wired logic applications with appropriate connections. Through-hole DIP package. Compatible with standard TTL logic circuits. Suitable for digital signal comparison.
