DESCRIPTION
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

USAGE CAUTIONS
1. This product is weak for static electricity by desig ned with high-speed integrated circuit so protect against static
electricity when handling.
2. By-pass capacitor of more than 0.1
F is used between V
DD
and GND near device. Al so, ensure that the
distance between the leads of the photocouple r and capacitor is no more than 10 mm.
