____________________________Fe a t u re s

The 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: high speed, high speed with

auto-standby, and low power. Propagation delay is 28ns

in high-speed mode, while supply current is only 250µA.

Supply current is reduced to 3µA in low-power mode.

♦ Three Operating Modes:

High Speed

High Speed with Auto-Standby

Low Power

♦ 28ns Propagation Delay (high-speed mode)

♦ 5µA Max Supply Current in Low-Power/

Auto-Standby Modes

The a uto-sta ndb y fe a ture a llows the c omp a ra tor 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 independently adjustable timeout periods for

each comparator using separate capacitors.

♦ +3V/+5V Single-Supply Operation

♦ Rail-to-Rail Outputs

♦ Ground-Sensing Input

♦ Internal Hysteresis (high-speed mode)

♦ Adjustable Timeout Period

♦ µMAX Package (MAX975)

QSOP-16 Package (MAX977)

The MAX975/MAX977’s inputs have a common-mode

voltage range of -0.2V to (V

- 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.
