Maxim MAX4520EUT-T, MAX4520EUA, MAX4510EUT-T, MAX4510EUA Datasheet

General Description

The MAX4510/MAX4520 single-pole/single-throw (SPST),
fault-protected analog switches feature a fault-protected
input and Rail-to-Rail®signal-handling capability. The
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 condi­tion, 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) fur­nishes 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: COM and IN pins are not fault protected. Signals on COM or IN exceeding V+ or V- are clamped by internal diodes. Limit

forward diode current to maximum current rating.

Note 2: NC and NO pins are fault protected. Signals on NC or NO exceeding -36V to +36V may damage the device. These limits

apply with power applied to V+ or V-, or ±40V with V+ = V- = 0.
