The 74AC11257 is a quadruple 2-to-1 multiplexer IC with 3-state outputs, designed using 74AC (Advanced CMOS) technology for high-speed and low-power operation. Each multiplexer selects between two data inputs, controlled by a select line and output enable pin, making it suitable for data routing, memory addressing, digital logic switching, and bus systems. Its 3-state outputs allow easy integration into bidirectional data buses and shared digital lines, reducing signal conflicts. With fast propagation delay, low static power dissipation, and strong noise immunity, the 74AC11257 is widely used in embedded systems, robotics, industrial automation, and consumer electronics. NeoGiga India supplies genuine 74AC11257 ICs with bulk B2B supply, institutional pricing, and nationwide express delivery, supporting OEMs, universities, and R&D labs across India.
