Description
1 Description
74V2G66
The 74V2G66 is an advanced high-speed CMOS dual bilateral switch developed using silicon gate C
2
MOS technology. It achieves high speed propagation delay and very low ON resistance, while maintaining true CMOS low power consumption. This bilateral switch handles rail-to-rail analog and digital signals that may vary across the full power supply range (from GND to V
CC
).
The C input is provided to control the switch, and it is compatible with standard CMOS output; the switch is ON (port I/O is connected to port O/I) when the C input is held high and
OFF (high impedance state exists between the two ports) when C is held low. It can be used in various applications, such as battery-powered systems and test equipment. It is available in the commercial and extended temperature range housed in a SOT23-8L package. All inputs and outputs are equipped with protection circuits to defend against static discharge, giving them ESD immunity and transient excess voltage protection.
