The 74ACT16543 is a 16-Bit Registered Transceiver with 3-State Outputs, designed for bidirectional data transfer with edge-triggered storage. Belonging to the 74ACT advanced CMOS family, this IC integrates sixteen D-type flip-flops with direction control and 3-state output enable, enabling both temporary data storage and controlled bus communication. With TTL-compatible inputs and CMOS-compatible outputs, the 74ACT16543 supports seamless interfacing across legacy TTL and modern CMOS systems. Operating at a 4.5V to 5.5V supply, it delivers fast propagation delay, high drive capability, low static power consumption, and robust noise immunity. Common applications include microprocessor buses, memory expansion, embedded controllers, industrial automation, IoT devices, and robotics. Available in SSOP, SOIC, and TSSOP packages, it is ideal for high-density PCB layouts and compact embedded systems. NeoGiga India supplies genuine, RoHS-compliant 74ACT16543 ICs with bulk B2B supply, institutional pricing, and nationwide fast delivery, serving OEMs, engineers, startups, and R&D labs.
