NOTES:
1. Signals on VS, VD or VIN exceeding V+ or V- will be clamped by internal diodes. Limit diode forward current to maximum current ratings.
2. Typical values are for design aid only, not guaranteed and not subject to production testing.
3. The algebraic convention whereby the most negative value is a minimum, and most positive value is a maximum, is used in this datasheet.
4.
OFF Isolation
=
20--V----S--- , where
VD
VS =
input
to OFF switch, and
VD = output
due to
VS .
5. ID(ON) is leakage from driver into “ON” switch.
6. Period of Reset (RS) pulse must be at least 50µs during or after power ON.
7. Parameter not tested. Parameter guaranteed by design or characterization.
