DESCRIPTION
NEC's PS2911-1 is an optically coupled isolator containing a
GaAs light emitting diode and an NPN silicon phototransistor
in one package for high density mounting applications. An ultra
small flat lead package has been provided which realizes a
reduction in mounting area of about 30% compared with the
PS28XX series.
