Pin Functions

PIN I/O DESCRIPTION
NAME NO.
VIN1 1 I Switch 1 input. Bypass this input with a ceramic capacitor to GND.
ON1 2 I Active-high switch 1 control input. Do not leave floating.
VBIAS 3 I Bias voltage. Power supply to the device. Recommended voltage range for this pin is 2.5 to 5.5 V. See VIN and VBIAS Voltage Range.
ON2 4 I Active-high switch 2 control input. Do not leave floating.
VIN2 5 I Switch 2 input. Bypass this input with a ceramic capacitor to GND.
VOUT2 6 O Switch 2 output
CT2 7 O Switch 2 slew rate control. Can be left floating.
GND 8 Ground
CT1 9 O Switch 1 slew rate control. Can be left floating.
VOUT1 10 O Switch 1 output
Thermal Pad Thermal pad (exposed center pad) to alleviate thermal stress. Tie to GND. See Layout Guidelines.
