Low-Voltage, CMOS Analog
Multiplexers/Switches

Detailed Description
The MAX4581L/MAX4582L/MAX4583L are low-voltage,
CMOS analog ICs that operate from a single supply of
+2V to +12V. The MAX4581L is configured as an 8-
channel multiplexer, the MAX4582L as two 4-channel
multiplexers, and the MAX4583L as three single-
pole/double-throw (SPDT) switches. These devices can
handle rail-to-rail analog signals with only 2nA of off-
leakage current at +25°C.
The MAX4581L/MAX4582L/MAX4583L are TTL/CMOS-
logic compatible with 0.8V to 2.0V logic thresholds for
all digital inputs when operating from a +12V supply.
Applications Information
Power-Supply Considerations
The MAX4581L/MAX4582L/MAX4583Ls’ construction is
typical of most CMOS analog switches. The supply
input, VCC, is used to power the internal CMOS switch-
es and sets the limit of the analog voltage on any
switch. Reverse ESD protection diodes are internally
connected between each analog signal pin and both
VCC and GND. If any analog signal exceeds VCC or
goes below GND, one of these diodes conducts.
During normal operation, these reverse-biased ESD
diodes leak, causing the only current drawn from VCC
or GND. Virtually all the analog leakage current comes
from the ESD diodes. Although the ESD diodes on a
given signal pin are identical, and therefore fairly well
balanced, they are reverse biased differently by either
VCC or GND and the analog signal. This means that
leakage varies as the analog signal varies. The differ-
ence in the two diodes’ leakage to VCC and GND con-
stitutes the analog signal-path leakage current.
Because there is no connection between the analog
signal paths and GND, all analog leakage current flows
between each pin and one of the supply terminals, not
to the other switch terminal. Because of this, both sides
of a given switch can show leakage currents of either
the same or opposite polarity.
VCC and GND power the internal logic and logic-level
translators, and set both the input and output logic lim-
its. The logic-level translators convert the logic levels
into switched VCC and GND signals to drive the gates
of the analog switches. This drive signal is the only
connection between the logic supplies (and signals)
and the analog supplies. The logic-level thresholds are
TTL/CMOS compatible when VCC is +12V.
Overvoltage Protection
Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maxi-
mum ratings because stresses beyond the listed rat-
ings can cause permanent damage to the devices.
Always sequence VCC first, followed by the logic inputs
and analog signals.
Pin Nomenclature
The MAX4581L/MAX4582L/MAX4583L are pin compati-
ble with the industry-standard 74HC4051/74HC4052/
74HC4053 and the MAX4051/MAX4052/MAX4053.
