±15kV ESD-Protected, Low-Voltage, Quad,
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.
