MCT5211SR2M

The MCT5211SR2M is a 1-channel 6-pin Phototransistor Optocoupler consists of a high-efficiency AlGaAs, infrared emitting diode, coupled with an NPN phototransistor. It is well suited for CMOS to LSTT/TTL interfaces, offering 250% CTR CE(SAT) with 1mA of LED input current. When an LED input current of 1.6mA is supplied data rates to 20K bits/s are possible. The MCT52XXM can easily interface LSTTL to LSTTL/TTL and with use of an external base to emitter resistor data rates of 100K bits/s can be achieved. It is suitable for CMOS to CMOS/LSTTL, LSTTL to CMOS/LSTTL logic isolation, RS-232 line receiver and AC line voltage sensing.
