DESCRIPTION
The 51992 is a high voltage current driver with DTL compatible TTL logic levels and drive a load up to 400 mA at 28V.
Should additional gating be required, AND inputs are provided along with an Expander connection. The addition of an
external capacitor provides control of the rise and fall times of the output in order to decrease cold lamp surges or to
minimize electromagnetic interference if long lines are driven. Device can be gated On and Off at normal inputs or at pin 8.
Since one side of the load is normally grounded there is less likelihood of false turn-on due to an inadvertent short in the
drive line.
Meets the requirements of SMD 5962-87617.
