7.3 Recommended Operating Conditions

over operating free-air temperature range (unless otherwise noted)
MIN NOM MAX UNIT
VDD Input supply voltage 1.5 10 V
VRESET, VRESET RESET pin and RESET pin voltage 0 10 V
IRESET, IRESET RESET pin and RESET pin current 0 ±5 mA
TJ Junction temperature (free air temperature) –40 125 °C
VMR(1) Manual reset pin voltage 0 VDD V
(1) If the logic signal driving MR is less than VDD, then additional current flows into VDD and out of MR. VMR should not be higher than VDD.
