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% 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.
