Broadcom ACPL 227 50BE dual channel optocoupler with 2 microsecond response time and 50 percent CTR
Product Overview
The Broadcom ACPL-227 and ACPL-247 are DC-input, multi-channel half-pitch phototransistor optocouplers designed for reliable signal transmission between circuits of different potentials and impedances. The ACPL-227 features a dual-channel configuration in an 8-pin SO package, while the ACPL-247 offers a quad-channel configuration in a 16-pin SO package. Both devices provide high input-output isolation voltage of 3750VRMS, a typical response time of 2 s, and a minimum Current Transfer Ratio (CTR) of 50% at 5 mA input current. These optocouplers are suitable for I/O interfaces in programmable controllers, computers, sequence controllers, system appliances, and measuring instruments.
