74V1G66 is a high-speed, low-power, single bilateral switch
The STMicroelectronics 74V1G66 is an advanced high-speed CMOS single bilateral switch fabricated in silicon gate CMOS technology. It is designed to handle rail-to-rail analog and digital signals across the full power supply range (2 V to 5.5 V) while maintaining low power consumption. The device features a high-speed propagation delay of 0.3 ns (typical) at 5 V and very low ON resistance, making it suitable for battery-powered systems and test equipment.
| ON resistance (typical) at 3.3 V | 8.5 Ω |
|---|---|
| Sine wave distortion (THD) | 0.04% |
| Operating voltage range | 2 V to 5.5 V |
| Package types | SOT23-5L, SOT323-5L |
| Operating temperature range | -55 to 125 °C |
The C input controls the switch; it is compatible with standard CMOS outputs and turns the switch ON when held high.
The 74V1G66 is available in SOT23-5L and SOT323-5L packages for commercial and extended temperature ranges.
When the control input is held low, the switch is OFF, resulting in a high impedance state between the two ports.
