HCPL-4100
Optically Coupled 20 mA Current Loop Transmitter
Data Sheet
Description
The HCPL-4100 optocoupler is designed to operate as a
transmitter in equipment using the 20 mA current loop.
20 mA current loop systems conventionally signal a
logic high state by transmitting 20 mA of loop current
(MARK), and signal a logic low state by allowing no
more than a few milliamperes of loop current (SPACE).
Optical coupling of the signal from the logic input to the
20 mA current loop breaks ground loops and provides very
high immunity to common mode interference.
The HCPL- 4100 data input is compatible with
LSTTL, TTL, or CMOS logic gates. The input integrated
circuit drives a GaAsP LED. The light emitted by the LED
is sensed by a second integrated circuit that allows 20 mA
to pass with a voltage drop of less than 2.7 volts when no
light is emitted and allows less than 2 mA to pass when
light is emitted. The transmitter output is capable of with-
standing 27 volts. The input integrated circuit provides
a controlled amount of LED drive current and takes into
account any LED light output degradation. The internal
shield allows a guaranteed 1000 V/µs common mode
transient immunity.
