.HCPL-0501-500E

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 6N135, HCPL-0500, and HCNW135 are for use in TTL/

CMOS, TTL/LSTTL or wide bandwidth analog applications.

Current transfer ratio (CTR) for these devices is 7% minimum at IF

= 16mA.

The 6N136, HCPL-2502, HCPL-0501, and HCNW136 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.
