The is a single, +3V/+5V dual-speed comparator with auto-standby in 8 pin µMAX package. It feature three different operating modes and are optimized for +3V and +5V single-supply applications. The operating modes are high speed, high speed with auto-standby and low power. 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 outputs are capable of rail to rail operation without external pull-up circuitry, making this device 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.
