General Description

The MAX4659/MAX4660 are medium voltage CMOS

analog switches with a low on-resistance of 25

Ω max

specifically designed to handle large switch currents.

With a switch capability of up to 200mA peak current

and 150mA continuous current (MAX4660), and up to

150mA peak current and 75mA continuous current

(MAX4659), these parts can switch loads as low as

50

Ω. They can replace reed relays with a million times

the speed and a virtually unlimited number of lifetime

cycles. Normal power consumption is only 3mW,

whether the switch is on or off. These parts are

TTL/CMOS compatible and will switch any voltage with-

in their power-supply range.

The devices are single-pole/double-throw (SPDT)

switches. The MAX4659/MAX4660 contain one normally

closed (NC) switch and one normally open (NO) switch.

The MAX4659/MAX4660s’ power-supply range is from

±4.5V to ±20V for dual-supply operation and +9V to

+40V for single-supply operation. These switches can

operate from any combination of supplies, within a 40V

V+ to V- range. They conduct equally well in either

The MAX4659 is available in 8-pin µMAX and SO pack-

ages. The MAX4660 is available in thermally enhanced

exposed paddle µMAX and SO packages.
