PHOTOCOUPLER
PS8741
FOR OPTICAL DAA, HIGH LINEAR
16-PIN SOP PHOTOCOUPLER
−NEPOC
Series−
DESCRIPTION
The PS8741 is an optically coupled isolator containing a GaAs LED on the input side and two photodiodes on the
output side.
It is suitable for analog control applications such as PCMCIA card, modem, voice telephony and fax machines.
FEATURES
• For PCMCIA
• Small and thin package (16-pin SOP: Pin pitch = 1.27 mm, Height = 2.1 mm)
• High transfer gain linearity (
∆
K
3

USAGE CAUTIONS
1. This product is weak for static electricity by designed with high-speed integrated circuit so protect against static
electricity when handling.
2. By-pass capacitor of more than 0.1
µ
F is used between V
CC
and GND near device. Also, ensure that the
distance between the leads of the photocoupler and capacitor is no more than 10 mm.
3. Avoid storage at a high temperature and high humidity.
