PS9121 Datasheet - Renesas

PS9121 5-PIN SOP (SO-5) 3.3V PHOTOCOUPLER

The PS9121 is an optically coupled high-speed, active low type isolator containing an AlGaAs LED on the input side and a photodiode and a signal processing circuit on the output side on one chip. The PS9121 is designed specifically for high common mode transient immunity (CMR) and low pulse width d.

PS9121 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.)

* Small package (SO-5)

* High-speed (15 Mbps)

* High isolation voltage (BV = 3 750 Vr.
