Part Details:

19-1141; Rev 2; 2/07 Single/Dual, +3V/+5V Dual-Speed Comparators with Auto-Standby MAX975/MAX977 General Description ____________________________Features The MAX975/MAX977 single/dual comparators feature Three Operating Modes: three different operating modes, and are optimized for High Speed +3V and +5V single-supply applications. The operating High Speed with Auto-Standby modes are as follows: high speed, high speed with Low Power auto-standby, and low power. Propagation delay is 28ns 28ns Propagation Delay (high-speed mode) in high-speed mode, while supply current is only 250µA.Supply current is reduced to 3µA in low-power mode. 5µA Max Supply Current in Low-Power/ The auto-standby feature allows the comparator to Auto-Standby Modes automatically change from low-power mode to high- +3V/+5V Single-Supply Operation speed mode upon receipt of an input signal. In the Rail-to-Rail Outputs absence of an input signal, the comparator revertsback to low-power mode after an adjustable timeout Ground-Sensing Input period. The timeout period for the MAX975 to enter Internal Hysteresis (high-speed mode) standby is set by a single capacitor. The dual MAX977features independently adjustable timeout periods for Adjustable Timeout Period each comparator using separate capacitors. µMAX Package (MAX975) The MAX975/MAX977 s inputs have a common-mode QSOP-16 Package (MAX977) voltage range of -0.2V to (VCC - 1.2V). The differential Ordering Information input voltage range extends rail to rail. The outputs arecapable of rail-to-rail operation without external pull-up PIN- PKG circuitry, making these devices ideal for interface with PART TEMP RANGE PACKAGE CODE CMOS/TTL logic. All inputs and outputs can tolerate acontinuous short-circuit fault condition to either rail. The MAX975ESA -40°C to +85°C 8 SO S8-2 comparator s internal hysteresis in high-speed mode MAX975EUA-T -40°C to +85°C 8 µMAX-8 U8-1 ensures clean output switching, even with slow-moving
