Product Description
Broadcom ACPL-227/ACPL-247 DC Input, Multi-Channel Half-Pitch Phototransistor Optocoupler
Product Overview
The Broadcom ACPL-227 and ACPL-247 are DC-input phototransistor optocouplers designed for reliable signal isolation. The ACPL-227 is a dual-channel device in an 8-pin SO package, while the ACPL-247 is a quad-channel device in a 16-pin SO package. Both offer high input-output isolation voltage of 3750VRMS and a typical response time of 2 s. They are suitable for applications requiring signal transmission between circuits of different potentials and impedances, including I/O interfaces for programmable controllers, computers, sequence controllers, system appliances, and measuring instruments.Product Attributes
