General Description

The MAX4620/MAX4630/MAX4640 low-voltage, high-

ESD-protected, quad, single-pole/single-throw (SPST)

analog switches are pin-compatible replacements for

the industry-standard 74HC4066 analog switch. The

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

protected against ±15kV electrostatic discharge (ESD)

without latchup or damage. Each switch can handle

Rail-to-Rail

analog signals. The 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

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

in battery-powered applications. The on-resistance is

70Ω max, matched between switches to 0.5Ω (typ),

and flat (2Ω typ) over the specified signal range.

The MAX4620 has four NO switches, the MAX4630 has

four NC switches, and the MAX4640 has two NO and

two NC switches. These devices are available in 14-pin

TSSOP, SO, and DIP packages.

MAX4620/MAX4630/MAX4640 ±15kV ESD-Protected, Low-Voltage, Quad, SPST, CMOS Analog Switches ±15kV ESD Protection The MAX4620/MAX4630/MAX4640 are ±15kV ESD-protected at the NC/NO terminals. To accomplish this, bidirectional SCRs are included on-chip between these terminals. When the voltages at these terminals go Beyond-the-RailsTM, the corresponding SCR turns on in a few nanoseconds and bypasses the surge safely to ground.
