74V1G66CTR Description

Short technical summary and product information.

The STMicroelectronics 74V1G66CTR is a high-speed CMOS single bilateral switch (SPST-NO configuration) capable of handling rail-to-rail analog and digital signals across the full supply range. It is fabricated in silicon gate C2MOS technology for low power consumption and high speed.

 

Key electrical specifications include a typical on-resistance of 6.5 Ohms at VCC=5V and 8.5 Ohms at VCC=3.3V, with a maximum on-resistance of 10 Ohms. The supply voltage range is 2V to 5.5V. The switch offers a -3dB bandwidth of 180 MHz, fast switching times (Ton 4ns max, Toff 7.5ns max), propagation delay of 0.3ns typical at 5V, and low sine wave distortion of 0.04% at 3.3V, 1kHz. Supply current is minimal at 1µA max at 25°C.

 

The device is packaged in a SOT-323-5 (SC-70-5) surface-mount package and operates over an extended temperature range of -55°C to 125°C. It is marked as RoHS3 compliant, MSL 1, and REACH unaffected, though these compliance statuses are unverified.

 

Typical applications include battery-powered systems, test equipment, analog signal switching, and audio routing where low on-resistance and high bandwidth are required.
