1.9 Switching Specifications

1 Falling propagation delay can be reduced by increasing instantaneous LED current drive, typically by increasing C

FWD .

2 Rising propagation delay depends on R

PU , CL , and IF .

Increasing IF above 2 • ITH (by reducing RS) increases the rising propagation delay.

3 Propagation Delay Skew is the worst case difference propagation delay, High to Low and Low to High between the two channels of a CPC5002

when measured using the test circuit shown below, which is tuned for approximately even rising and falling delays.
