EN2 10 I Output enable 2. Output pins on side 2 are enabled when EN2 is high or open and in high-impedance state when EN2 is low.
GND1 2,8 — Ground connection for VCC1
GND2 9,15 — Ground connection for VCC2
INA 3 I Input, channel A
INB 3 I Input, channel B
INC 12 I Input, channel C
NC 6, 11 Not internally connected, do not connect in application
OUTA 14 O Output, channel A
OUTB 14 O Output, channel B
OUTC 5 O Output, channel C
VCC1 1 — Power supply, side 1
