74V2G66STR

Analog Switches, Multiplexers, Demultiplexers Overview

The STMicroelectronics 74V2G66STR is a dual bilateral analog switch fabricated in advanced high-speed silicon gate C2MOS technology. It provides two independent single-pole single-throw (SPST) switches within an SOT23-8L package. The device operates across a wide supply voltage range of 2 V to 5.5 V, handling rail-to-rail analog and digital signals from ground to VCC. Key electrical characteristics include a typical propagation delay of 0.3 ns at 5 V and 0.4 ns at 3.3 V, with a maximum quiescent supply current of 1 μA. The on-resistance is typically 6.5 Ω at 5 V and 8.5 Ω at 3.3 V.
