.The HCPL-3140-560E is an optocoupler logic-out push-pull DC-IN 1-CH 8-pin PDIP SMD T/R unit manufactured by Broadcom. It is a commonly used component in analog and digital communications systems for signal isolation, impedance matching, noise suppression, and synchronization. The HCPL-3140-560E comprises of an infrared LED coupled with an integrated photo detector to act as an electrical signal isolator which help prevent electrical surges and spikes from derailing a system’s performance. The package is offered in an 8-pin PDIP SMD, and comes with a forward voltage of 2.2V max and an open-collector output current of 10mA max. It also has maximum power dissipation of 500mW. The HCPL-3140-560E is used in a wide range of applications, including motors, medical equipment, industrial automation, and communications systems.
