NEC's 4 PIN SOP
SOLID STATE RELAY
PS7241-1A
FEATURES
DESCRIPTION
• 1 CHANNEL TYPE
(1a output)
NEC's PS7241-1A is a solid state relay containing a GaAs LED
on the input side and a MOSFET on the output side. It is
suitable for analog signal control because of its low offset and
high linearity.
• DESIGNED FOR AC/DC SWITCHING LINE CHANGER
• SMALL PACKAGE
