ISL32450E Datasheet, PDF (7/21 Pages) Intersil Corporation – ±60V Fault Protected, 3.3V to 5V, ±20V Common Mode Range, RS-485/RS-422 Transceivers with Cable Invert and ±15kV ESD

ISL32450E, ISL32452E, ISL32453E, ISL32455E, ISL32457E
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 9). Boldface limits apply over the operating temperature range, -40°C to +85°C. (Continued)
