Overview
The 74V2G66STR is an advanced high-speed CMOS dual bilateral switch developed by STMicroelectronics using silicon gate C2MOS technology. This component is designed to achieve high-speed propagation delay and very low ON resistance while maintaining true CMOS low power consumption. It is capable of handling rail-to-rail analog and digital signals across the full power supply range (from GND to VCC). The switch is controlled by the C input, which is compatible with standard CMOS output, and it operates in an ON state when the C input is high and in an OFF state (high impedance) when the C input is low.
