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. 7. Supply current specification is valid for loaded drivers when DE = 0V (RS-485 mode only). 8. Applies to peak current. See “Typical Performance Curves” starting on page 19 for more information. 9. 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. 10. VCC ≤ 5.25V. 11. Parts are 100% tested at +25°C. Over-temperature limits established by characterization and are not production tested. Electrical Specifications Test Conditions: VCC = 4.5V to 5.5V, C1 - C4 = 0.1µF, VL = VCC (for QFN only); Unless Otherwise Specified. Typicals are at VCC = 5V, TA = +25°C (Note 6).
