ISL3178AE Datasheet, PDF (5/14 Pages) Intersil Corporation – ±15kV ESD Protected, 3.3V, Full Fail-Safe, Low Power, High Speed or Slew Rate Limited, RS-485/RS-422 Transceivers

ISL3178AE
Electrical Specifications
Test Conditions: V_CC = 3.0V to 3.6V; Unless Otherwise Specified. Typicals are at V_CC = 3.3V, T_A = +25°C,
(Note 2). Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified.
Temperature limits established by characterization and are not production tested.
