Description

The MCT52XX series consists of a high-efficiency AlGaAs, infrared emitting diode, coupled with an NPN phototransistor in a six pin dual-in-line package.

The MCT52XX is well suited for CMOS to LSTT/TTL interfaces, offering 250 CTRCE(SAT) with 1 mA of LED input current. When an LED input current of 1.6 mA is supplied data rates to 20K bits/s are possible.

The MCT52XX 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.

Features

• High CTRCE(SAT) comparable to Darlingtons

• CTR guaranteed 0°C to 70°C

• High common mode transient rejection 5kV/µs

• Data rates up to 150 kbits/s (NRZ)

• Underwriters Laboratory (UL) recognized (file #E90700)

• VDE recognized (file #94766)

– Add option 300 (e.g., MCT5211.300)

Applications

• CMOS to CMOS/LSTTL logic isolation

• LSTTL to CMOS/LSTTL logic isolation

• RS-232 line receiver

• Telephone ring detector

• AC line voltage sensing

• Switching power supply
