DESCRIPTION
The 53267 latching solid state relay (SSR) has no mechanical contact therefore it is immune to contact-related problems
(such as arcing, contamination, cycle life, etc.) associated with its electromechanical equivalent. Input/output isolation
barrier of the device is provided using optocoupler as shown in the functional block diagram (Figure 1). The control input
has a built-in current limiting resistor making it possible to directly interface to TTL logic signal. The contact uses a N-
channel enhancement mode MOSFET for low on-state resistance and is configured as a low-side switch. This results in
low power dissipation, which allows operation over the temperature range of 55C to +125C with minimal heat sinking.
In the absence of its bias voltage, the switch is default to the high impedance (off) state, i.e., open contact mode.
The control circuitry of the device is designed in a manner that the MOSFET turns completely off before it will turn on
emulating the break-before-make feature of the equivalent mechanical contact. Contact is toggled by applying a short
pulse at the control input resulting in very low average power dissipation and suitable for computer control applications.
The proprietary design of the solid state contact provides a "memory" capability for latching on (close) or off (open)
without reset upon removal of power.
The MOSFET switch in the device operates as a SPST. There is a status line available the monitoring the contact
position. The status output is an open collector signal will require an appropriate external pull-up resistor for it to works
properly. The device is encased in a hermetically sealed 10-pin TO-5 metal package. This SSR is available in a variety of
quality levels from COTS to class K including any custom screening requirements. The basic data sheet part is
environmentally screened to H level in accordance with Table C-IX of MIL-PRF-38534.
