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
