DESCRIPTION
The 53253 is two power MOSFET optocouplers in a single 8-pin dual-in-line package suitable for applications where
two independent switches and radiation tolerant performance are required. The popular hermetic eight-pin dual-in-line
ceramic package combined with 1000 VDC isolation between input and output and between two isolated relays,
makes this device ideal for solid-state relay applications. Performance is specified over the full military temperature
range. This device is available as COTS, or screened to MIL-PRF-38534, Table C-IX, Class H or custom screening.
Lead options support both through-hole and surface-mount assembly. Gold plated leads are standard, but other lead
finishes per MIL-PRF-38534 are also available.
Functionally, the device operates as two SPST, normally open (2 Form A) solid-state relays. Each relay is actuated by
an input current, which can be driven from a standard TTL device. The input current biases a light emitting diode that is
optically coupled to an integrated photovoltaic diode array. The photovoltaic diode array energizes control circuitry that
operates the output MOSFET.
