Operation notes
(1)
Power supply voltages 1 and 2 (V
M
and V
CC
)
The rise and fall order for the power supply voltages 1
and 2 (V
M
and V
CC
5) is as follows.
Rise: power supply voltage 1 (V
M
) on
voltage 2 (V
CC
5) on
Fall: power supply voltage 2 (V
CC
5) off
voltage 1 (V
M
) off
(2)
Logic and analog input pins
Due to the circuit construction, when the logic and analog
input pins are open, it is equivalent to a high-level input.
(3)
Thermal shutdown (TSD)
power supply
power supply
At Tj = 150 C (min.), all logic input voltages go low (chan-
nels A, AB, B and BB).
Therefore, the outputs (OUTA, AB, B and BB) all go high
impedance.
The TSD has approximately 35 C of hysteresis.
(4)
V
CC
5 pin
When V
CC
5 is open, it is internally pulled down to ground
via a resistor (20k
(Typ.)).
(5)
Heat sink
Be certain to connect the heatsink to GND.
