Description
The ASSR-32XX Series consists of an AlGaAs infrared
light-emitting diode (LED) input stage optically coupled
to a high-voltage output detector circuit. The detector
consists of a high-speed photovoltaic diode array and
driver circuitry to switch on/off two discrete high volt-
age MOSFETs. The relay turns on (contact closes) with a
minimum input current of 3mA through the input LED.
The relay turns off (contact opens) with an input voltage
of 0.8V or less.
The single channel configurations, ASSR-3210 and ASSR-
3211, are equivalent to 1 Form A Electromechanical
Relays (EMR), and the dual channel configuration, ASSR-
3220, is equivalent to 2 Form A EMR. They are available
in 4-pin SO, 6-pin DIP, 8-pin DIP and Gull Wing Surface
Mount for DIP packages. Their electrical and switching
characteristics are specified over the temperature range
of -40°C to +85°C. They are used for general purpose
switching of signals and low power AC/DC loads.
ASSR-3211 enables AC/DC and DC-only output connec-
tions. For DC-only connection, the output current, Io,
increases to 0.4A and the on-resistance, R(ON) reduces
to 2.5.
