These devices offer several monitor options with
adjustable input thresholds (see Table 1). The threshold
voltage at each adjustable IN_ input is typically 0.394V
(TOL = GND) or 0.372 (TOL = V
V
shown in Figure 10.
Large resistors can be used to minimize current through
the external resistors. For greater accuracy, use lower-
value resistors.
Connect any unused IN_ inputs to a voltage above its
threshold.
The OUT_ outputs go low when their respective IN_
inputs drop below their specified thresholds. The output
is open drain with a 30µA internal pullup to V
many applications, no external pullup resistor is required
to interface with other logic devices. An external pullup
resistor to any voltage from 0 to 5.5V overrides the inter-
nal pullup if interfacing to different logic supply voltages.
Internal circuitry prevents reverse current flow from the
external pullup voltage to V
