ASM161/ASM162

rev 1.5

Electrical Characteristics

Unless otherwise noted, VCC is over the full range and TA = 0°c to 70°c for ASM161/162 X C and TA = -40°c to +85°c for ASM161/162 X E devices. Typical

values at TA = 25°c, VCC = 5V for L/M/J devices, VCC = 3.3V for T/S devices and VCC = 3V for R devices
