FST3253QSC

Signal Switches, Multiplexers, Decoders Overview

The FST3253QSC is a dual 4:1 multiplexer/demultiplexer bus switch manufactured by ON Semiconductor. It operates within a supply voltage range of 4.0V to 5.5V and supports an operating temperature from -40°C to +85°C. The device features a typical on-resistance of 4Ω at VCC=4.5V with a 64mA load, and a quiescent supply current of 3µA. Propagation delay is typically 0.25ns for bus-to-bus switching. It utilizes a 16-lead Quarter Size Outline Package (QSOP) conforming to JEDEC MO-137 standards.
