MAX9075/MAX9077 Low-Cost, Ultra-Small, 3A Single-Supply Comparators General Description Features The MAX9075/MAX9077 single/dual comparators are 580ns Propagation Delay from Only 3A optimized for 3V and 5V single-supply applications. 2.1V to 5.5V Single-Supply Operation These comparators have a 580ns propagation delay and consume just 3A per comparator. The combination of Ground-Sensing Inputs low-power, single-supply operation down to 2.1V, and Rail-to-Rail Outputs ultra-small footprint makes these devices ideal for all portable applications. No Output Phase Inversion for Overdriven Inputs The MAX9075/MAX9077 have a common-mode input No Differential Clamp Across Inputs voltage range of -0.2V to V - 1.2V. Unlike many com- CC Available in Ultra-Small Packages parators, there is no differential clamp between the 5-Pin SC70 (MAX9075) inputs, allowing the differential input voltage range to 8-Pin SOT23 (MAX9077) extend rail-to-rail. All inputs and outputs tolerate a con- tinuous short-circuit fault condition to either rail. The design of the output stage limits supply-current Ordering Information surges while switching (typical of many other compara- PIN- TOP tors), minimizing power consumption under dynamic PART* TEMP RANGE PACKAGE MARK conditions. Large internal push-pull output drivers allow rail-to-rail output swing with loads up to 2mA, making MAX9075EXK+T -40C to +85C 5 SC70 AAC+ these devices ideal for interface with TTL/CMOS logic.
