SPECIFICATIONS
ELECTRICAL CHARACTERISTICS
4.5 V ≤ V DD1 ≤ 5.5 V; each voltage is relative to its respective ground. All minimum/maximum specifications apply over the entire
recommended operating range, unless otherwise noted. All typical specifications are at T A = 25°C, V DD1 = 5.0 V, V ISO = 5.0 V.
