NEC's HIGH NOISE REDUCTION
25 Mbps CMOS OUTPUT TYPE
8-PIN DIP OPTOCOUPLER
DESCRIPTION
PS9661, PS9661L
NEC’s PS9661 and PS9661L are optically coupled isolators containing a GaAlAs LED on the input side and a CMOS
output IC on the output side.
These photocouplers are high common mode transient immunity (CMR), high-speed CMOS output type devices,
making them ideal for high-speed logic interface circuits.
The PS9661 is in a plastic DIP (Dual In-line Package) and the PS9661L is lead bending type (Gull-wing) for surface
mounting.
FEATURES
• High-speed response (25 Mbps)
• High common mode transient immunity (CM
