description<br />
These high-speed optocouplers are designed for use in analog or digital interface applications that require<br />
high-voltage isolation between the input and output. Applications include line receivers that require high<br />
common-mode transient immunity, and analog or logic circuits that require input-to-output electrical isolation.<br />
The <strong>6N135</strong>, <strong>6N136</strong>, and <strong>HCPL4502</strong> optocouplers each consists of a light-emitting diode and an integrated<br />
photon detector composed of a photodiode and an open-collector output transistor. Separate connections are<br />
provided for the photodiode bias and the transistor-collector output. This feature, which reduces the transistor<br />
base-to-collector capacitance, results in speeds up to one hundred times that of a conventional phototransistor<br />
optocoupler.<br />
The <strong>6N135</strong> is designed for TTL/CMOS, TTL/LSTTL, and wide-band analog applications.<br />
The <strong>6N136</strong> and <strong>HCPL4502</strong> are designed for high-speed TTL/TTL applications. The <strong>HCPL4502</strong> has no base<br />
connection.<br />

IMPORTANT NOTICE<br />
Texas Instruments (TI) reserves the right to make changes to its products or to discontinue any semiconductor<br />
product or service without notice, and advises its customers to obtain the latest version of relevant information<br />
to verify, before placing orders, that the information being relied on is current and complete.<br />
TI warrants performance of its semiconductor products and related software to the specifications applicable at<br />
the time of sale in accordance with TI’s standard warranty. Testing and other quality control techniques are<br />
utilized to the extent TI deems necessary to support this warranty. Specific testing of all parameters of each<br />
device is not necessarily performed, except those mandated by government requirements.<br />
Certain applications using semiconductor products may involve potential risks of death, personal injury, or<br />
severe property or environmental damage (“Critical Applications”).<br />
TI SEMICONDUCTOR PRODUCTS ARE NOT DESIGNED, INTENDED, AUTHORIZED, OR WARRANTED<br />
TO BE SUITABLE FOR USE IN LIFE-SUPPORT APPLICATIONS, DEVICES OR SYSTEMS OR OTHER<br />
CRITICAL APPLICATIONS.<br />
Inclusion of TI products in such applications is understood to be fully at the risk of the customer. Use of TI<br />
products in such applications requires the written approval of an appropriate TI officer. Questions concerning<br />
potential risk applications should be directed to TI through a local SC sales office.<br />
In order to minimize risks associated with the customer’s applications, adequate design and operating<br />
safeguards should be provided by the customer to minimize inherent or procedural hazards.<br />
TI assumes no liability for applications assistance, customer product design, software performance, or<br />
infringement of patents or services described herein. Nor does TI warrant or represent that any license, either<br />
express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property<br />
right of TI covering or relating to any combination, machine, or process in which such semiconductor products<br />
or services might be or are used.<br />
