MAX975/MAX977 19-1141; Rev 2; 2/07 Single/Dual, +3V/+5V Dual-Speed Comparators with Auto-Standby General Description 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.
The auto-standby feature allows the comparator to automatically change from low-power mode to highspeed mode upon receipt of an input signal.
In the absence of an input signal, the comparator reverts back to ...
