The 74ACT11257 is a Quad 2-Input Multiplexer IC with 3-State Outputs, belonging to the 74ACT advanced CMOS family with TTL-compatible inputs. It features four multiplexers that select between two data inputs under common control, making it highly effective for signal routing, data management, and digital system design. With its 3-state output enable, the IC allows multiple devices to share common buses without conflict. Operating on a 4.5V to 5.5V supply, the 74ACT11257 provides fast propagation delay, high noise immunity, and low static power consumption. It is widely used in microprocessor buses, memory interfacing, embedded systems, IoT controllers, robotics, PLCs, and industrial automation. Available in PDIP, SOIC, and TSSOP packages, it supports both prototyping and compact PCB designs. NeoGiga India supplies genuine, RoHS-compliant 74ACT11257 ICs with bulk B2B supply, institutional pricing, and nationwide fast delivery, serving OEMs, startups, engineers, and R&D institutions.
