Digital Optical Isolator
Description
The CPC5002 is a dual high speed optical logic
isolator with open-drain outputs providing 3750V
rms
of
galvanic isolation between the inputs and the outputs.
Activating the input LED causes the open-drain output
to turn on, pulling the voltage of the external pullup
resistor towards ground. Utilizing CMOS technology
enables the output stage’s high-gain circuitry to
operate with a miserly power consumption of <5mW
(typical) when operated with a 3.3V supply voltage
and a low input LED drive current of 1.5mA.
Because optical isolators pass logic levels directly
there is no internal state refresh clock to maintain a
non-changing input. Additionally, the CPC5002 will
always return the buffered signals to their proper value
after a transient interruption at either side.

Falling propagation delay can be reduced by increasing instantaneous LED current drive, typically by increasing C
FWD
.
Rising propagation delay depends on R
PU
, C
L
, and I
F
.
Increasing I
F
above 2 • I
TH
(by reducing R
S
) increases the rising propagation delay.
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.
