ICPL4502
HIGH SPEED, NON BASE LEAD
OPTICALLY COUPLED ISOLATOR
PHOTOTRANSISTOR OUTPUT
APPROVALS
l UL recognised, File No. E91231
DESCRIPTION
These diode-transistor optocouplers use a light
emitting diode and an integrated photon detector to
provide 2500Volts
input and output. Seperate connection for the
electrical isolation between
RMS
photodiode bias and output transistor collector
improve the speed up to a hundred times that of a
conventional photo-transistor coupler by reducing
the base-collector capacitance.
FEATURES
l High speed - 1 MBits/s
l High Common Mode Transient
Immunity 10000V/µs typical
l Pin 7 not connected to give enhanced
Noise Immunity
l TTL Compatible
l 2 MHz Bandwidth
l Open Collector Output
l 2500V
l Options :-
Withstand Test Voltage,1 Min
RMS
10mm lead spread - add G after part no.
Surface mount - add SM after part no.
Tape&reel - add SMT&R after part no.
l All electrical parameters 100% tested
l Custom electrical selections available
APPLICATIONS
l Line receivers
l Pulse transformer replacement
l Wide bandwidth analog coupling
l Output interface to CMOS-LSTTL-TTL
