ISL32430E Datasheet, PDF (8/21 Pages) Intersil Corporation – ±40V Fault Protected, 3.3V to 5V, ±15V Common Mode Range, RS-485/RS-422 Transceivers With Cable Invert and ±15kV ESD

ISL32430E, ISL32432E, ISL32433E, ISL32435E, ISL32437E
Electrical Specifications Test Conditions: V_CC = 3V to 3.6V and 4.5V to 5.5V; Unless Otherwise Specified. Typicals are at the worst
case of V_CC = 5V or V_CC = 3.3V, T_A = +25°C (Note 8). Boldface limits apply over the operating temperature range, -40°C to +85°C. (Continued)
