Maxim Integrated 

Dual USB Switch with Fault

Blanking and Autoreset

ELECTRICAL CHARACTERISTICS (continued)

(Circuit of Figure 1, VIN = VINA = VINB = 5V, ONA = ONB = GND (MAX1823/MAX1823A), ONA = ONB = IN (MAX1823B/MAX1823H),

TA = 0°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.)
