CTRL 10 — — — I Failsafe output control. Output state is determined by CTRL pin when DISABLE is high or VCC1 is powered down. Output is high when CTRL is high or open and low when CTRL is low.
DISABLE 7 — — — I Input disable. All input pins are disabled when DISABLE is high and enabled when DISABLE is low or open.
EN — 10 — — I Output enable. All output pins are enabled when EN is high or open and disabled when EN is low.
EN1 — — 7 7 I Output enable 1. Output pins on side 1 are enabled when EN1 is high or open and disabled when EN1 is low.
EN2 — — 10 10 I Output enable 2. Output pins on side-2 are enabled when EN2 is high or open and disabled when EN2 is low.
GND1 2, 8 2, 8 2, 8 2, 8 — Ground connection for VCC1
