Normally 5V. GND (Pin 6): Ground. +IN (Pin 2): Noninverting Input. Q OUT (Pin 7): Noninverting Logic Output. This pin is high when +IN is above –IN and LATCH ENABLE is low. –IN (Pin 3): Inverting Input. Q OUT (Pin 8): Inverting Logic Output. This pin is low V– (Pin 4): Negative Supply Voltage. Normally either 0V or when +IN is above –IN and LATCH ENABLE is low. – 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.
