Overview
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)
