MTL3C92
SINGLE CHANNEL OPTOCOUPLER
(Direct Replacement for 3C92C)
Features:
High Reliability
Base lead eliminated for improved noise immunity
Rugged package
Stability over wide temperature
+500V electrical isolation
Applications:
Eliminate ground loops
Level shifting
Line receiver
Switching power supplies
Motor control
DESCRIPTION
The
MTL3C92
contains a gallium arsenide infrared LED optically coupled to a silicon planar phototransistor. The optocoupler is
built on a TO-46 header. The anode of the LED is electrically connected to the case. This optocoupler is capable of
transmitting signals between two galvanic sources. The potential difference between transmitter and receiver should not go
over the maximum isolation voltage. The internal base connection has been eliminated for improved noise immunity.
