Specifications
(typical values under recommended operating conditions, unless specified)
Parameter Value Unit
Data rate 120 kbps

Notes
  • Use five capacitors; C1 between pins 1 and 3, C2 between pins 4 and 5, C3 between pin 2 and +5v, C4 between ground and pin 6, and C5 between +5V and ground. See datasheet for schematic.
  • C1 through C5 should be 1.0 µF electrolytic capacitors.

Note
Data is maintained by an independent source and accuracy is not guaranteed. Check with the manufacturer's datasheet for up-to-date information.
