Pin Functional Description
650
SOURCE (S1, S2, S3) Pins :
600
Internally connect to the SOURCEs of MOSFETs 1, 2 and 3
respectively.
550
DRAIN (D1, D2, D3) Pins :
500
Internally connect to the DRAINs of MOSFETs 1, 2 and 3
respectively.
450
VOLTAGE SUPPLY (VCC) pin
400
The internal MOSFETs are fully turned on when the VCC pin
voltage is V_CC(ON) (see parameter table) or more greater than their
350
SOURCE voltage relative to GROUND. VCC pin should be
connected to GROUND to turn the MOSFETs off.
