Overview
The 74V1G66STR is an advanced high-speed CMOS single bilateral switch produced by STMicroelectronics. Fabricated in silicon gate C2MOS technology, this component is designed to achieve high speed propagation delay and very low ON resistances while maintaining true CMOS low power consumption. The switch is capable of handling rail-to-rail analog and digital signals across the full power supply range (from GND to VCC). It features an enable input (C) that is compatible with standard CMOS outputs, allowing the switch to be turned ON or OFF based on the input state.
