description

These high-speed optocouplers are designed for use in analog or digital interface applications that require

high-voltage isolation between the input and output. Applications include line receivers that require high

common-mode transient immunity, and analog or logic circuits that require input-to-output electrical isolation.

The 6N135, 6N136, and HCPL4502 optocouplers each consists of a light-emitting diode and an integrated

photon detector composed of a photodiode and an open-collector output transistor. Separate connections are

provided for the photodiode bias and the transistor-collector output. This feature, which reduces the transistor

base-to-collector capacitance, results in speeds up to one hundred times that of a conventional phototransistor

optocoupler.

The 6N135 is designed for TTL/CMOS, TTL/LSTTL, and wide-band analog applications.

The 6N136 and HCPL4502 are designed for high-speed TTL/TTL applications. The HCPL4502 has no base

connection.
