The PS9351L and PS9351L2 are optically coupled isolator containing a GaAlAs LED on the input side and a CMOS output IC on the output side. The PS9351L and PS9351L2 are in 6-pin plastic SDIP (Shrink Dual In-line Package). The PS9351L2 has 8 mm creepage distance. The mount area of 6-pin plastic SDIP is half size of 8-pin DIP. This photocoupler is high common mode transient immunity (CMR), a high-speed CMOS output type device designed for high-speed logic interface circuits. The PS9351L is lead bending type (Gull-wing) for surface mounting. The PS9351L2 is lead bending type for long creepage distance (Gull-wing) for surface mount.
