Electrical Specifications
NOTES:
10. Applies to peak current. See “Typical Performance Curves” beginning on page 18 for more information.
12. V
13. The Slew pin has a pull-up resistor that enables only when in RS-485 mode (485/232 = V
14. ON, RXEN, and DEN all simultaneously switched Low-to-High.
15. Parts are 100% tested at +25°C. Over-temperature limits established by characterization and are not production tested.
