LMX331/LMX393/LMX339 19-1958 Rev 4 5/11 General-Purpose, Low-Voltage, Single/Dual/Quad, Tiny-Pack Comparators General Description Features The LMX331/LMX393/LMX339 single/dual/quad com- Guaranteed 1.8V to 5.5V Performance parators are drop-in, pin-for-pin-compatible replace- -40C to +125C Automotive Temperature Range ments for the LMV331/LMV393/LMV339. The LMX331H/ LMX393H/LMX339H offer the performance of the Low Supply Current (60A/Comparator at LMX331/LMX393/LMX339 with the added benefit of inter- V = 5.0V) DD nal hysteresis to provide noise immunity, preventing out- Input Common-Mode Voltage Range Includes put oscillations even with slow-moving input signals. Ground Advantages of the LMX331/LMX393/LMX339 series No Phase Reversal for Overdriven Inputs include low supply voltage, small package, and low cost. The LMX331 is available in both 5-pin SC70 and SOT23 Low Output Saturation Voltage (100mV) packages, LMX393 is available in both 8-pin MAX and Internal 2mV Hysteresis smaller SOT23 packages, and the LMX339 is available in (LMX331H/LMX393H/LMX339H) 14-pin TSSOP and SO packages. They are manufac- tured using advanced submicron CMOS technology. 5-Pin SC70 Space-Saving Package Designed with the most modern techniques, the (2.0mm 2.1mm 1.0mm) LMX331/LMX393/LMX339 achieve superior performance (LMX331/LMX331H) over BiCMOS or bipolar versions on the market. Ordering Information The LMX331/LMX393/LMX339 offer performance advantages such as wider supply voltage range, wider PIN- TOP operating temperature range, better CMRR and PSRR, PART TEMP RANGE PACKAGE MARK improved response time characteristics, reduced off- LMX331AXK+T -40C to +125C 5 SC70 ACD set, reduced output saturation voltage, reduced input bias current, and improved RF immunity.
