MC74VHC1G66DFT2G

The MC74VHC1G66DFT2G is a single-pole single-throw (SPST) Analog Switch achieves high speed propagation delays and low ON resistances while maintaining low power dissipation. This bilateral switch controls analog and digital voltages that may vary across the full power-supply range (from VCC to GND). The MC74VHC1G66 is compatible in function to a single gate of the high speed CMOS MC74VHC4066 and the metal-gate CMOS MC14066. The device has been designed so that the ON resistances (RON) are much lower and more linear over input voltage than RON of the metal-gate CMOS or high speed CMOS analog switches. The ON/OFF control inputs are compatible with standard CMOS outputs. The ON/OFF control input structure provides protection when voltages between 0V and 5.5V are applied, regardless of the supply voltage. This input structure helps prevent device destruction caused by supply voltage - input/output voltage mismatch, battery backup, hot insertion, etc.
