The Broadcom AC input half-pitch phototransistor optocouplers contain two light-emitting diodes connected inversely parallel and optically coupled to a phototransistor(s). They are packaged in a 4-pin SO package (single-channel) and in an 8-pin SO package.
Input-output isolation voltage is rated at 3000 VRMS. Response time (tr) is 2 µs typically, while minimum current transfer ratio (CTR) is 20% at an input current of 1 mA.
Features
- CTR: 20% (min) at IF = ± 1 mA, VCC = 5 V
- High input-output isolation voltage: VISO = 3000 VRMS
- Non-saturated tr: 2 μs (typ) at VCC = 10 V, IC = 2 mA, RL = 100 Ω
- SO package
- CMR 10 kV/μs (typ)
- Safety and regulatory approvals
- cUL
- IEC/EN/DIN EN 60747-5-5
- Options available:
Applications
- I/O interface for programmable controllers, computers
- Sequence controllers
- System appliances, measuring instruments
- Signal transmission between circuits of different potentials and impedances
