General Description

The MAX4575/MAX4576/MAX4577 are low-voltage,

high electrostatic discharge (ESD)-protected, dual sin-

gle-pole/single-throw (SPST) analog switches. The nor-

mally closed (NO) and normally open (NC) pins are

protected against ±15kV ESD without latchup or dam-

nals. Off-leakage current is 0.5nA at +25°C. These

analog switches are suitable for low-distortion audio

applications and are the preferred solution over

mechanical relays in automated test equipment or

applications where current switching is required. They

have low power requirements (0.5µW), require less

board space, and are more reliable than mechanical

relays. Each device is controlled by TTL/CMOS input

voltage levels and is bilateral.

These switches feature guaranteed operation from a

single supply of +2V to +12V, making them ideal for

use in battery-powered applications. On-resistance is

70

Ω (max), matched between switches to 0.5Ω (typ)

and flat (2

Ω typ) over the specified signal range.

The MAX4575 has two NO switches, the MAX4576 has

two NC switches, and the MAX4577 has one NO and

one NC switch. These devices are available in 8-pin

µMAX and SO packages.
