25Ω SPST Analog Switches in SOT23-6

General Description

The MAX4647/MAX4648 are dual-supply single-pole/sin-

gle-throw (SPST) switches. On-resistance is 25Ω max and

flat (2Ω max) over the specified signal range. Each switch

can handle rail-to-rail analog signals. Off-leakage current

is only 1nA max at +25°C. They conduct analog or digital

signals equally well in either direction. The primary appli-

cation areas are in the switching and routing of signals in

telecommunications and test equipment.

The MAX4647/MAX4648 are single SPST analog switches.

The MAX4647 has one normally closed (NC) switch, and

the MAX4648 has one normally open (NO) switch. These

devices operate from a single +9V to +36V supply or from

dual ±4.5V to ±20V supplies. The MAX4647/MAX4648 are

available in tiny 6-pin SOT23 packages.
