HCPL-0452/0453/4502/4503
Single Channel, High Speed Optocouplers
Data Sheet
Lead (Pb) Free
RoHS 6 fully
compliant
RoHS 6 fully compliant options available;
-xxxE denotes a lead-free product
Description
These diode-transistor optocouplers use an insulating
layer between a LED and an integrated photodetector to
provide electrical insulation between input and output.
Separate connections for the photodiode bias and out-
put-transistor collector increase the speed up to a hun-
dred times that of a conventional phototransistor coupler
by reducing the base-collector capacitance.
These single channel optocouplers are available in
8-Pin DIP, SO-8 and Widebody package configurations.
The HCPL-4502/4503 and HCNW4502/4503 are designed
for high speed TTL/TTL applications. A standard 16 mA TTL
sink current through the input LED will provide enough
output current for 1 TTL load and a 5.6 kΩ pull-up resistor.
CTR for these devices is 19% minimum at I
F
= 16 mA.
