____________ Applications Information
Interfacing to Different
Logic Voltage Components
The MAX6377/MAX6380 have an active-low, open-
drain output. This output structure sinks current when
OUT is asserted. Connect a pullup resistor from OUT to
any supply voltage up to 5.50V (Figure 1). Select a
resistor value large enough to allow a valid logic low
(see Electrical Characteristics), and small enough to
register a logic high while supplying all input current
and leakage paths connected to the OUT line.
Negative-Going V
CC
Transients
These devices are relatively immune to short-duration,
negative-going V
CC
transients (glitches). The Typical
Operating Characteristics show the Maximum Transient
Duration vs. Threshold Overdrive graph, for which out-
put pulses are not generated. The graph shows the
maximum pulse width that a negative-going V
CC
tran-
sient may typically have before the devices issue out-
put signals. As the amplitude of the transient increases,
the maximum-allowable pulse width decreases.

The MAX6375/MAX6376/MAX6377 are available in factory-preset
thresholds from 2.20V to 3.08V, in approximately 0.1V increments.
The MAX6378/MAX6379/MAX6380 are available in factory-preset
thresholds from 3.30V to 4.63V, in approximately 0.1V increments.
Choose the desired threshold suffix from Table 1 and insert it in
the blank spaces following R. There are 21 standard versions,
with a required order increment of 2500 pieces. Sample stock is
generally held on the standard versions only (see the Selector
Guide). The required order increment is 10,000 pieces for non-
standard versions (Table 2). Contact factory for availability. All
devices available in tape-and-reel only.
Devices are available in both leaded and lead-free packaging.
Specify lead-free by replacing “-T” with “+T” when ordering.
