Optocoupler; SMD; Ch:1; OUT: transistor; 3.75kVrms; 30kV/µs; CTR@If: 21-68%@12mA; Gull wing 8
High CMR, High Speed Optocouplers
High CTR at TA = 25°C
>25% for HCPL-4504/0454
The HCPL-4504 and HCPL-0454 contain a GaAsP LED
while the HCPL-J454 and HCNW4504 contain an AlGaAs
LED. The LED is optically coupled to an integrated high
gain photo detector.
Applications
- Inverter circuits and Intelligent Power Module (IPM)
interfacing: High Common Mode Transient immunity
(> 10 kV/μs for an IPM load/drive) and (tPLH - tPHL)
Specifi ed (see Power Inverter Dead Time section)
- Line receivers: Short propagation delays and low input-output capacitance
- High speed logic ground isolation: TTL/TTL, TTL/CMOS, TTL/LSTTL
- Replaces pulse transformers: Save board space and weight
- Analog signal ground isolation: Integrated photodetector provides
improved linearity over phototransistors
