Our advantages 

Chinese manufacturing processes have undergone years of iteration, resulting in mature and reliable technologies. Many international corporations opt for production outsourcing in China. As an electronic components manufacturer in China, our products can fully replace those of major international brands in 99% of applications without the need for testing verification. Our products boast high consistency in quality, reasonable pricing, ample inventory, flexible supply, short lead times, and professional after-sales service. 

Features

• AC input response

• Current transfer ratio ( CTR : MIN. 20% at l_F= ±1mA , V_CE = 5V )

• Wide Operating temperature range -55~110℃

• High input-output isolation voltage ( Viso= 5,000Vrms )

• Response time (tr:TYP. 4us at V_CE=2V,l_C=2mA,R_L=100)

• High collector-emitter voltage (V_CE≧ 80V)

• MSL Class 1

Description

The SL844 series of four channel devices each consist of two infrared emitting diodes, connected in inverse parallel, optically coupled to a photo transistor detector.

They are packaged in a 4-pin DIP package and available in side-lead spacing and SMD option.

Applications

• AC line monitor

• Programmable controllers

• Telephone line interface

• Unknown polarity DC sensor
