SFH6319T中文资料威世数据手册PDF规格书

DESCRIPTION

The SFH6318 is ideal for TTL applications since the 300

minimum current transfer ratio with an LED current of

1.6 mA enables operation with one unit load-in and one

unit load-out with a 2.2 k pull-up resistor.

The SFH6319 is best suited for low power logic

applications involving CMOS and low power TTL. A 400

current transfer ratio with only 0.5 mA of LED current is

guaranteed from 0 °C to 70 °C.

Very high current ratio together with 4000 VRMS isolation are

achieved by coupling an LED with an integrated high gain

photo detector in a SOIC-8 package. Separate pins for

the photo diode and output stage enable TTL compatible

saturation voltages with high speed operation.

Photodarlington operation is achieved by tying the VCC and

VO terminals together. Access to the base terminal allows

adjustment to the gain bandwidth.
