PHOTOCOUPLER
PS9821-1,-2
HIGH CMR, 15 Mbps OPEN COLLECTOR OUTPUT TYPE
8-PIN SSOP (SO-8)
3.3 V HIGH-SPEED PHOTOCOUPLER
−NEPOC Series−
DESCRIPTION
The PS9821-1 and PS9821-2 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 PS9821-1, -2 are designed specifically for high common mode transient immunity (CMR) and low pulse width
distortion, PS9821-2 is suitable for high density applications.
FEATURES
• Low power consumption (VCC = 3.3 V)
• Pulse width distortion (⏐tPHL−tPLH⏐ = 35 ns MAX.)
• High common mode transient immunity (CMH, CML = ±15 kV/μs MIN.)
• 40% reduction of mounting area (5-pin SOP × 2)
• High-speed (15 Mbps)
• High isolation voltage (BV = 2 500 Vr.m.s.)
• Open collector output
