CMOS Analog Switch
The Hl-390 switch is a monolithic device fabricated using
CMOS technology and the Intersil dielectric isolation process.
This device is TTL compatible and features low leakage and
supply currents, low and nearly constant ON resistance over
the analog signal range, break-before-make switching and
low power dissipation.

NOTE:
11. The net leakage into the source or drain is the N-Channel leakage minus the P-Channel leakage. This difference can be positive, negative or
zero depending on the analog voltage and temperature, and will vary greatly from unit to unit.
