DESCRIPTION
The PS2732 and PS2733 are optically coupled isolators
containing a GaAs light emitting diode and an NPN silicon
Darlington-connected phototransistor. Each is mounted in a
plastic SOP (Small Out-line Package) for high density appli-
cations.
APPLICATIONS
Interface circuit for various instrumentations and control
equipment.
• REPLACEMENT FOR RELAY IN PULSE-DIAL
CIRCUIT
• HIGH CTR CIRCUIT APPLICATIONS
