General Description
The MAX9647/MAX9648 comparators are drop-in, pin-for-pin compatible replacements for the LMX331/LMX331H. The MAX9648 has the added benefit of internal hysteresis to provide noise immunity, preventing output oscillations even with slow moving input signals.

Features
♦ Guaranteed +1.8V to +5.5V Performance
♦ -40NC to +125NC Automotive Temperature Range
♦ Low Supply Current (60µA/Channel at
   VDD = +5.0V)
♦ Input Common-Mode Voltage Range Includes
   Ground
♦ No Phase Reversal for Overdriven Inputs
♦ Low Output Saturation Voltage (120mV)
♦ Internal 2mV Hysteresis (MAX9648)
♦ 5-Pin SC70 Space-Saving Package
   (2.0mm x 2.1mm x 1.0mm)
