MAX49140

30ns, Low-Power, 3V/5V, Rail-to-Rail Single-

Supply Comparator

General Description

Benefits and Features

The MAX49140 is a single high-speed comparator opti-

mized for systems powered from a 3V or 5V supply. The

MAX49140 combines high speed, low power, and rail-to-

rail inputs. Propagation delay is 30ns, while supply current

is only 100μA (typ).

● Fast, 30ns Propagation Delay (10mV Overdrive)

● Low-Power 100μA Supply Current (V = 3V)

● Optimized for 3V and 5V Applications

● Rail-to-Rail Input Voltage Range

● Low, 500μV Offset Voltage

● Internal Hysteresis for Clean Switching

● Output Swing 300mV of Power Rails

● CMOS/TTL-Compatible Outputs

● Small SC70 Package

The input common-mode range of the device extends up

to both power-supply rails. The output pulls to within 0.3V

of either supply rail without external pullup circuitry, mak-

ing the device ideal for interfacing with both CMOS and

TTL logic. All input and output pins can tolerate a con-

tinuous short-circuit fault condition to either rail. Internal

hysteresis ensures clean output switching, even with slow-

moving input signals.

● AEC-Q100 Qualified

Ordering Information appears at end of data sheet.

The MAX49140 is offered in tiny, 5-pin SC70 package and

is fully specified over -40°C to +125°C automotive temper-

ature range. The device is AEC-Q100 qualified.

Applications

● Car Battery-Powered Systems

● Line Receivers

● Threshold Detectors/Discriminators

● 3V/5V Systems

● Zero-Crossing Detectors

● Sampling Circuits
