Single/Dual, +3V/+5V Dual-Speed  
Comparators with Auto-Standby  
General Description  
____________________________Features  
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 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 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  
CC  
Ordering Information  
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.
