Description

High Speed Optocoupler, SFH6138, 100 kBd, Low Input Current, High Gain

High common mode transient immunity and very high current ratio together with 5300 VRMS insulation are achieved by coupling an LED with an integrated high gain photon detector in an eight pin dual-in-line package. SFH6138 has Separate pins for the photo diode and output stage enable TTL compatible saturation voltages with high speed operation.

Photodarlington operation of SFH6138 is achieved by tying the VCC and VO terminals together. Access to the base terminal allows adjustment to the gain bandwidth.

The SFH6138 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 SFH6138 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.
