CIRCUIT DESCRIPTION
Outputs
The totem-pole outputs have been designed to minimize
cross-conduction current spikes while maximizing fast,
high-current rise and fall times. Current limiting can be
done externally either at the outputs or at the common
V
C
pin. The output diodes included have slow recovery
and should be shunted with high-speed external diodes
when driving high-frequency inductive loads.
Flip/Flop
Grounding pin 7 activates the internal flip-flop to alter-
nate the two outputs. With pin 7 open, the two outputs
operate simultaneously and can be paralleled for higher
current operation. Since the flip-flop is triggered by the
digital input, an off-time of at last 200nsec must be pro-
vided to allow the flip/flop to change states. Note that the
circuit logic is configured such that the “OFF” state is de-
fined as the outputs low.
Digital Inputs
With both an inverting and non-inverting input available,
either active-high or active-low signals may be accepted.
These are true TTL compatible inputs—the threshold is
approximately 1.2V with no hysteresis; and external pull-
up resistors are not required.
Inhibit Circuit
Although it may have other uses, this circuit is included to
eliminate the need for deadband control when driving
relatively slow bipolar power transistors. A diode from
each inhibit input to the opposite power switch collector
will keep one output from turning-on until the other has
turned-off. The threshold is determined by the voltage on
pin 15 which can be set from 0.5 to 3.5V. When this cir-
cuit is not used, ground pin 15 and leave 1 and 16 open.
