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
•Ordering number of tape product : PS9821-1-F3, F4: 1 500 pcs/reel
:PS9821-2-F3, F4: 1 500 pcs/reel
•Pb-Free product
•Safety standards
•UL approved: File No. E72422
•DIN EN60747-5-2 (VDE0884 Part2) approved No.40008347 (option)
