DESCRIPTION
The SL5500, SL5501, SL5504 and SL5511 are optically coupled isolators each consisting of an infrared emitting GaAs diode and
a silicon NPN phototransistor with accessible base. These devices are housed in 6-pin dual-in-line packages (DIP).
FEATURES
High output/input DC current transfer ratio
Low saturation voltage
High isolation voltage of 5.3 kV RMS
UL recognized (File # E90700)
VDE recognized (File # 94766)
- Ordering option `300' (e.g. SL5500.300)
APPLICATIONS
