The MAX4510/MAX4520 single-pole/single-throw (SPST),
fault-protected analog switches feature a fault-protected
input and Rail-to-Rail
normally open (NO) and normally closed (NC) terminals
are protected from overvoltage faults up to 36V during
power-on and 44V with power off. During a fault condi-
tion, the switch input terminal (NO or NC) becomes an
open circuit; only nanoamperes of leakage current flow
from the fault source, and the switch output (COM) fur-
nishes up to 13mA of the appropriate polarity supply
voltage to the load. This ensures unambiguous rail-to-rail
outputs when a fault begins and ends.
On-resistance is 160Ω max. The off-leakage current is
only 0.5nA at +25°C and 10nA at +85°C. The MAX4510
is a normally closed switch, while the MAX4520 is a
normally open switch. These CMOS switches operate
with dual power supplies ranging from ±4.5V to ±20V
or a single supply between +9V and +36V.
The digital input has +0.8V and +2.4V logic thresholds,
ensuring both TTL- and CMOS-logic compatibility when
using ±15V or a single +12V supply. The MAX4510/
MAX4520 are available in 6-pin SOT23 and 8-pin µMAX
packages.
