HCPL-4503-560E

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 output-transistor collector increase the speed up to a hundred 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 IF=16mA.

Functional Diagram

A 0.1 μF bypass capacitor must be connected between pins 5 and 8.
