Overview
The 74CBTLV3257PW/S911, produced by Nexperia USA Inc., is a quad 1-of-2 high-speed multiplexer/demultiplexer. This device features common select (S) and output enable (OE) inputs, making it versatile for various digital switching applications. The low ON-state resistance of the switch allows connections to be made with minimal propagation delay and without generating additional ground bounce noise. This component is fully specified for partial-power-down applications, ensuring isolation during power-off and supporting Ioff for safe operation in power-down modes.
