Single/Dual / +3V/+5V Dual-Speed Comparators with Auto-Standby
General DescriptionThe MAX975/MAX977 single/dual comparators feature
three different operating modes, and are optimized for
+3V and +5V single-supply applications. The operating
modes are as follows: highspeed, highspeed with
auto-standby, and lowpower. Propagation delay is 28ns
in high-speed mode, while supply current is only 250mA.
Supply current is reduced to 3µA in low-power mode.
The auto-standby feature allows the comparator to
automatically change from low-power mode to high-
speed mode upon receipt of an input signal. In the
absence of an input signal, the comparator reverts
back to low-power mode after an adjustable timeout
period. The timeout period for the MAX975 to enter
standby is set by a single capacitor. The dual MAX977
features independentlyadjustable timeout periods for
each comparator using separate capacitors.
The MAX975/MAX977’s inputs have a common-mode
voltage range of -0.2V to (VCC- 1.2V). The differential
input voltage range extends rail to rail. The outputs are
capable of rail-to-rail operation without external pull-up
circuitry, making these devices ideal for interface with
CMOS/TTL logic. All inputs and outputs can tolerate a
continuous short-circuit fault condition to either rail. The
comparator’s internal hysteresis in high-speed mode
ensures clean output switching, even with slow-moving
input signals.
The single MAX975 is available in 8-pin SO and 8-pinMAX packages, while the dual MAX977 is available in
14-pin SO and 16-pin QSOP packages.

ELECTRICAL CHARACTERISTICS(VCC= +2.7V to +5.25V, specifications are for high-speed mode, TA= -40°C to +85°C, unless otherwise noted. Typical values are at= +25°C.) (Note 1)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

ELECTRICAL CHARACTERISTICS (continued)(VCC= +2.7V to +5.25V, specifications are for high-speed mode, TA= -40°C to +85°C, unless otherwise noted. Typical values are at= +25°C.) (Note 1)
Note 1:The MAX975EUA is 100% production tested at TA= +25°C; all temperature specifications are guaranteed by design.
Note 2:Inferred by CMRR. Either input can be driven to the absolute maximum limit without false output inversion, as long as the
other input is within the specified common-mode input voltage range.
Note 3:VOSis defined as the mean of trip points. The trip points are the extremities of the differential input voltage required to make
the comparator output change state (Figure 1).
Note 4:The difference between the upper and lower trip points is equal to the width of the input-referred hysteresis zone (Figure 1).
Note 5:Guaranteed by design. The LP pin is sensitive to noise. If fall times larger than 10µs are expected, bypass LP to ground
using a 0.1µF capacitor.
Note 6:Propagation delay is guaranteed by design. For low-overdrive conditions, VOS is added to the overdrive. The following
equation defines propagation-delay skew: tSKEW= tPD+- tPD-.
