SWITCHING CHARACTERISTICS The

denotes the specifications which apply over the specified operating

temperature range, otherwise specifications are at TA = 25°C. LTM2887-3 VCC = 3.3V, LTM2887-5 VCC = 5V, VL = 3.3V, and GND =

GND2 = 0V, ON = VL unless otherwise noted. Specifications apply to all options unless otherwise noted.
