GND (Pin 8):
GND connection.
DI3 (Pin 9):
Driver 3 input. Refer to DI1.
DO3A (Pin 10):
Driver 3 output.
DO3B (Pin 11):
Driver 3 output.
EN34 (Pin 12):
Driver 3 and 4 outputs enabled. See
Function Table for details.
DO4B (Pin 13):
Driver 4 output.
DO4A (Pin 14):
Driver 4 output.
DI4 (Pin 15):
Driver 4 input. Refer to DI1.
V
CC
(Pin 16):
Positive supply; 4.75 < V
CC
< 5.25.
DI1 (Pin 1):
Driver 1 input. If Driver 1 is enabled, then a low
on DI1 forces the driver outputs DO1A low and DO1B high.
A high on DI1 with the driver outputs enabled will force
DO1A high and DO1B low.
DO1A (Pin 2):
Driver 1 output.
DO1B (Pin 3):
Driver 1 output.
EN12 (Pin 4):
Driver 1 and 2 outputs enabled. See Func-
tion Table for details.
DO2B (Pin 5):
Driver 2 output.
DO2A (Pin 6):
Driver 2 output.
DI2 (Pin 7):
Driver 2 input. Refer to DI1.
