U74LVC1G66
CMOS IC
SINGLE BILATRAL ANALOG
SWITCH
DESCRIPTION

The U74LVC1G66 is a high-speed CMOS device.
The U74LVC1G66 has two data input/output pins(A and B) and
an active HIGH enable input pin(C) .
The U74LVC1G66 can handle both analog and digital signals.
The signals can be transmitted in either direction when enable pin is
high . The analog switch is off when enable pin is low.
FEATURES

* Operation Voltage Range: 1.65~5.5V
* Low Power Dissipation: ICC=10μA(Max)
* Inputs Accept Voltages to 5.5V
* Max Tpd of 0.8 ns at 3.3V
* High Degree of Linearity

Notes: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
