Inputs (channels 1 to 4 and
the independent operational
amplifier)
Logic inputs
The IC is set to one of four
modes, forward, reverse,
brake, and free running by
the combination of high and
low values applied to these
pins.
Channel 1 to 4 outputs
H bridge (loading) output and
loading output setting
BTL amplifier output on/off
state setting.
High: output on
Low: output off
