74V1G66

Single bilateral switch

SOT23-5L

SOT323-5L

Description

The 74V1G66 is an advanced high-speed CMOS single bilateral switch fabricated in silicon gate

2

C

MOS technology. It achieves high speed propagation delay and very low ON resistances 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 outputs. 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 many applications as battery powered systems or test equipments.
