V
is measured over the full common-mode input voltage range.
Because of the p-n-p input stage, the direction of the current is out of the device. This current essentially is constant (i.e., independent of
the output state). No loading change exists on the reference or input lines as long as the common-mode input voltage range is not
exceeded.
The output sink current is a function of the output voltage. These devices have a bimodal output section that allows them to sink (via a
Darlington connection) large currents at output voltages greater than 1.5 V and smaller currents at output voltages less than 1.5 V.
