Features
Description
The ASSR-14XX 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 volt-
age of 0.8V or less.
Compact Solid-State Bi-directional Signal Switch
Single and Dual Channel Normally-off Single-Pole-
Single-Throw (SPST) Relay
60V Output Withstand Voltage
0.6A or 1.2A Current Rating
(See Schematic for ASSR-1411 Connection A and B)
Low Input Current: CMOS Compatibility
Low On-Resistance:
0.2 Typical for DC-only,
0.7 Typical for AC/DC
The single channel configurations, ASSR-1410 and
ASSR-1411, are equivalent to 1 Form A Electromechani-
cal Relays (EMR), and the dual channel configuration,
ASSR-1420, 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.
Very High Output Off-state Impedance:
10 Teraohms Typical
High Speed Switching:
0.1ms (Ton), 0.02ms (Toff) Typical
High Transient Immunity: >1kV/s
High Input-to-Output Insulation Voltage
(Safety and Regulatory Approvals)
- 3750 Vrms for 1 min per UL1577
- CSA Component Acceptance
ASSR-1411 enables AC/DC and DC-only output connec-
tions. For DC-only connection, the output current, Io,
increases to 1.2A and the on-resistance, R
reduces
(ON)
to 0.5.
