Electrical Specifications Test Conditions: VCC = 3.15V to 3.45V, C1 - C4 = 0.1µF; unless otherwise specified. Typicals are at VCC = 3.3V,
TA = +25°C (Note 10). (Continued)Boldface limits apply across the operating temperature range, -40°C to +85°C. (Continued)

NOTES:
10. 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.
11. Supply current specification is valid for loaded RS-485 (port 2) drivers when DE485 = 0V.
12. Applies to peak current. See “Typical Performance Curves on page 12” for more information.
13. A, B, RxIN defaults to RS-485 mode (>15kΩ) when the device is unpowered (VCC = 0V), or in SHDN.
14. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
