Latch enable input pin, non-inverting side.
Pin is not connected inside the package.
Connect package pin to GND for improved noise.
Positive supply voltage for the output stage.
Inverting output. Q bar is at logic low if the analog voltage
at the non-inverting input, INP, is greater than the analog
voltage at the inverting input, INN, provided that the
comparator is in compare mode. Refer to the LE/LE bar
descriptions (pins 6, 7) for more information.
Non-inverting output. Q is at logic high if the analog voltage
at the non-inverting input, INP, is greater than the analog
voltage at the inverting input, INN, provided that the
comparator is in compare mode. Refer to the LE/LE bar
descriptions (pins 6, 7) for more information.
Hysteresis Control pin. This pin should be left disconnected
for zero hysteresis. Connect to Vee with a resistor to add
the desired amount of hysteresis. Refer to Figure on page
6-42. to determine the correct sizing of Rhys hysteresis
control resistor.
Negative power supply, -3V.
RTN
Return for ESD protection.
Package Base
Exposed paddle must be connected to Vee.
