The HI-303 switch is a monolithic device fabricated using
CMOS technology and the Intersil dielectric isolation
process. This switch features break-before-make switching,
low and nearly constant ON resistance over the full analog
signal range, and low power dissipation.
Features
• Analog Signal Range (15V Supplies) . . . . . . . . . . 15V
o
• Low Leakage at 25 C . . . . . . . . . . . . . . . . . . . . . . . 40pA
o
• Low Leakage at 125 C . . . . . . . . . . . . . . . . . . . . . . . 1nA
The HI-303 is TTL compatible and has a logic “0” condition
with an input less than 0.8V and a logic “1” condition with an
input greater than 4V. (See pinouts for switch conditions with
a logic “1” input.)

NOTE: Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with
both SnPb and Pb-free soldering operations. Intersil Pb-free products
are MSL classified at Pb-free peak reflow temperatures that meet or
exceed the Pb-free requirements of IPC/JEDEC J STD-020C.
