PS9814-1,-2
HIGH CMR, 10 Mbps OPEN COLLECTOR OUTPUT TYPE
8-PIN SSOP (SO-8)
−NEPOC
HIGH-SPEED PHOTOCOUPLER
DESCRIPTION
The PS9814-1 and PS9814-2 are active-low type high-speed photocouplers that use a GaAlAs light-emitting diode
on the input side and a photodetector IC that includes a photodiode and a signal processor on the same chip on the
output side.
The PS9814-1, -2 are designed specifically for high common mode transient immunity (CMR) and low pulse width
distortion, the PS9814-2 is suitable for high density applications.

Because V

CC
= 2.6 V or
less, it is important to confirm the characteristics (operation with the power supply on and off) during design,
before using this device.
