NOTES:
7. All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless
otherwise specified.
8. Supply current specification is valid for loaded drivers when DE = 0V (RS-485 mode) or DEN = 0V (RS-232 mode).
9. Applies to peak current. See “Typical Performance Curves” for more information.
10. RIN defaults to RS-485 mode (>15kΩ) when the device is unpowered (VCC = 0V), or in SHDN, regardless of the state of the SEL inputs.
11. 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.
Electrical Specifications
Test Conditions: VCC = 3.15V to 3.45V, C1 - C4 = 0.1F, VL = VCC (for QFN only); Unless Otherwise Specified.
Typicals are at VCC = 3.3V, TA =+25°C (Note 7) (Continued)
