PIN FUNCTIONS
V+ (Pin 1): Positive Supply Voltage. Normally 5V.
+IN (Pin 2): Noninverting Input.
–IN (Pin 3): Inverting Input.
V– (Pin 4): Negative Supply Voltage. Normally either 0V
or – 5V.
LATCH ENABLE (Pin 5): Latch Control Pin. When high, the
outputs remain in a latched condition, independent of the
current state of the inputs.
GND (Pin 6): Ground.
Q OUT (Pin 7): Noninverting Logic Output. This pin is high
when +IN is above – IN and LATCH ENABLE is low.
Q OUT (Pin 8): Inverting Logic Output. This pin is low
when +IN is above – IN and LATCH ENABLE is low.
