SENSOR is a PNP comparator input which accepts a sine wave
input or a square wave input. This input is protected from excur-
sions above V
CC
as well as any below ground, as long as the cur-
rent is limited to 1.5mA. It has an active clamp set to zero volts to
prevent negative input voltages from disrupting normal opera-
tion. The sensor input can withstand 150V
DC
as long as the input
current is limited to 1.5mA max using a series resistor of 100k.
Simultaneously energizing the source and sink on either leg is
not permitted. i.e. Q1 & Q2 or Q3 & Q4 cannot be energized
simultaneously.
Circuit function is not affected by inductive transients due to coil
loads as specified in Transition States section.
The transition states occur as indicated in Table 1 without any
intermediate states permitted.

The polarity definition for the coil driver outputs is as follows:

The speed sensor input frequency is divided by one or divided
by two by connecting the divider select input, (Pin 5) as follows:
Logic 0 = divide by 2
Logic 1 = divide by 1
