B LT A (B<A)
B LT A (B<A)—B less than A is an Analog
Comparator with two Analog Inputs and one Digital
(On/Off) Output. A fixed Hysteresis Band of 0.1% of
Input B span is applied to these comparators.
INPUT A
INPUT B
OUTPUT (Y)
B<A
Y
= 1 if B<
A
Y
= 0 if (B + .001 * Span of B) >A
Example: (B<A)
B = 900 (Range 0 – 1000)
900 – (1000 * .001) = 899
If A >900, then Output is ON(1)
If A <899, then Output is OFF (0)
B GT A (B>A)
B GT A (B>A)—B greater than A is an Analog
Comparator with two Analog Inputs and one Digital
(On/Off) Output. A fixed Hysteresis Band of 0.1% of
Input B span is applied to these comparators.
INPUT A
INPUT B
OUTPUT (Y)
B>A
Y
= 1 if B>
A
Y
= 0 if (B + .001 * Span of B) <
A
Example: (B>A)
B = 900 (Range 0 – 1000)
900 +(1000 * .001) = 901
If A <900, then Output is ON(1)
If A >901, then Output is OFF (0)
GATE(n)INA
(n = 1, 2, 3, 4, or 5)
GATE (n) INPUT A—The selection here will indicate
what Input A will be for any of the 5 Gates you want
to configure.
The following selections apply if the Gate Type is
OR, NOR, AND, NAND, X OR, or X NOR.
