• Manufacturer Part Number: EPC700
• Description: 24V/50mA General-Purpose Output-Driver
• Manufacturer: EPC [Espros Photonics corp]

The delay time is set with d
table for the 8 different delay times.
An un-configured chip is applying a default delay time of 50µs corresponding to [d
The recovery time is set to o
table for the 8 different recovery time delay values.
An un-configured chip is applying the default recovery time of 500ms corresponding to [o
Programming Example
An example for changing the delay time to 100µs is shown in the following diagram:
