74V1G66 Single bilateral switch Features High speed: t = 0.3 ns (typ.) at V = 5 V PD CC t = 0.4 ns (typ.) at V = 3.3 V PD CC Low power dissipation: I = 1 A (max.) at T =25C CC A LowO resistance: SOT23-5L R =6.5 (typ.) at V = 5 V I = 1 mA ON CC I/O R = 8.5 (typ.) at V = 3.3 V I = 1 mA ON CC I/O Sine wave distortion: 0.04% at V = 3.3V f = 1kHz CC SOT323-5L Wide operating range: V (opr) = 2 V to 5.5 V CC Improved latch-up immunity Description The 74V1G66 is available in the commercial and The 74V1G66 is an advanced high-speed CMOS extended temperature range in SOT23-5L and single bilateral switch fabricated in silicon gate SOT323-5L packages. 2 C MOS technology. It achieves high speed All inputs and outputs are equipped with propagation delay and very low ON resistances protection circuits against static discharge, giving while maintaining true CMOS low power them ESD immunity and transient excess voltage. 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. Table 1.
