Introduction

AI Translation

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 5.6kΩ pull-up resistor. CTR for these devices is 19% minimum at lF = 16mA
