Enable Input (ENABLE or ENABLE )
The MAX6895/MAX6897 offer an active-high enable
input (ENABLE), while the MAX6896/MAX6898/MAX6899
offer an active-low enable input ( ENABLE ). With V IN above
V TH , drive ENABLE high ( ENABLE low) to force OUT high
( OUT low) after the adjustable delay time (A versions). For
P version devices, when V IN > 0.5V and enable is assert-
ed, the output asserts after typically 150ns.
The enable input has logic-high and logic-low voltage
thresholds of 1.4V and 0.4V, respectively. For both ver-
sions, when V IN > 0.5V, drive ENABLE low ( ENABLE
high) to force OUT low ( OUT high) within 150ns typ.
Output (OUT or OUT )
The MAX6895/MAX6899 offer an active-high, push-pull
output (OUT), and the MAX6896 offers an active-low
push-pull output ( OUT ). The MAX6897 offers an active-
high open-drain output (OUT), and the MAX6898 offers
an active-low open-drain output ( OUT ).
Push-pull output devices are referenced to V CC . Open-
drain outputs can be pulled up to 28V.

Applications Information
Input Threshold
The MAX6895–MAX6899 monitor the voltage on IN with
an external resistive divider (see R1 and R2 in the
Typical Operating Circuit). Connect R1 and R2 as close
to IN as possible. R1 and R2 can have very high values
to minimize current consumption due to low IN leakage
currents (±15nA max). Set R2 to some conveniently
high value (1M Ω , for example) and calculate R1 based
on the desired monitored voltage using the following
formula:
? V ?
? V IN ?
where V MONITOR is the desired monitored voltage and
V IN is the detector input threshold (0.5V).
