Overview
The MC74VHC1G66DFT2G, produced by onsemi, is a single pole single throw (SPST) analog switch. This device is designed to achieve high speed propagation delays and low ON resistances while maintaining low power dissipation. It is compatible with the High Speed CMOS MC74VHC4066 and the metal-gate CMOS MC14066, but offers improved linearity and lower ON resistance over input voltage. The MC74VHC1G66 is suitable for controlling both analog and digital voltages across the full power-supply range from VCC to GND.
