MAX975, MAX977 Single/Dual, +3V/+5V Dual-Speed Comparators With Auto-Standby

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 250A. Supply current is reduced to 3A in low-power mode.
The auto-standby feature allows the Comparator to automatically change from low-power mode to highspeed mode 508 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.
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-pin MAX packages, while the dual MAX977 is available in 14-pin SO and 16-pin QSOP packages.
