ICPL2730
ICPL2731
HIGH SPEED DUAL CHANNEL
OPTICALLY COUPLED ISOLATOR
PHOTODARLINGTON OUTPUT
APPROVALS
l UL recognised, File No. E91231
DESCRIPTION
These dual channel diode-darlington optocouplers
use a pair of light emitting diodes and an integrated
high gain photon detectors to provide 2500Volts
electrical isolation between input and output.
RMS
Seperate connection for the photodiode bias and
output darlington collector improve the speed up to
a hundred times that of a conventional photodarlington coupler by reducing the base-collector
capacitance.
FEATURES
l High speed - DC to 200kBits/s operation
l High Common Mode Transient
Immunity 10kV/µs typical
l TTL Compatible - 0.1V V
l Low Input Current Requirement - 0.5mA
l High Current Transfer Ratio - 2000% typ.
l Open Collector Output
l 2500V
l ICPL2731 has improved noise shield
Withstand Test Voltage, 1 min
