鹵15kV ESD-Protected, Low-Voltage, Dual, SPST,
CMOS Analog Switches
MAX4575/MAX4576/MAX4577
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 鹵15kV ESD without latchup or dam-
age. Each switch can handle Rail-to-Rail
廬
analog sig-
nals. Off-leakage current is 0.5nA at +25擄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 (0.5碌W), 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鈩?(max), matched between switches to 0.5鈩?(typ)
and flat (2鈩?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
碌MAX and SO packages.
