Description
The MCT52XXM series consists of a high-efficiency AlGaAs, infrared emitting diode, coupled with an NPN phototransistor in a six pin dual-in-line package.
The MCT52XXM is well suited for CMOS to LSTT/TTL interfaces, offering 250% CTRCE(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.

FEATUREs
■ High CTRCE(SAT) comparable to Darlingtons
