Low-Voltage, CMOS Analog
Multiplexers/Switches
_______________General Description
The MAX4051/MAX4052/MAX4053 and MAX4051A/
MAX4052A/MAX4053A are low-voltage, CMOS analog
ICs configured as an 8-channel multiplexer (MAX4051/A),
two 4-channel multiplexers (MAX4052/A), and three sin-
gle-pole/double-throw (SPDT) switches (MAX4053/A).
The A-suffix parts are fully characterized for on-resistance
match, on-resistance flatness, and low leakage.
These CMOS devices can operate continuously with
dual power supplies ranging from ±2.7V to ±8V or a
single supply between +2.7V and +16V. Each switch
can handle rail-to-rail analog signals. The off leakage
current is only 0.1nA at +25°C or 5nA at +85°C
(MAX4051A/MAX4052A/4053A).
All digital inputs have 0.8V to 2.4V logic thresholds,
ensuring TTL/CMOS-logic compatibility when using
±5V or a single +5V supply.

__________Applications Information
Power-Supply Considerations
Overview
The MAX4051/MAX4052/MAX4053 and MAX4051A/
MAX4052A/MAX4053A construction is typical of most
CMOS analog switches. They have three supply pins:
V+, V-, and GND. V+ and V- are used to drive the inter-
nal CMOS switches and set the limits of the analog volt-
age on any switch. Reverse ESD-protection diodes are
internally connected between each analog signal pin
and both V+ and V-. If any analog signal exceeds V+ or
V-, one of these diodes will conduct. During normal
operation, these (and other) reverse-biased ESD diodes
leak, forming the only current drawn from V+ or V-.
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. Each is biased by
either V+ or V- and the analog signal. This means their
leakages will vary as the signal varies. The difference in
the two diode leakages to the V+ and V- pins consti-
tutes the analog signal path leakage current. All analog
leakage current flows between each pin and one of the
supply terminals, not to the other switch terminal. This is
why both sides of a given switch can show leakage cur-
rents of either the same or opposite polarity.
There is no connection between the analog signal
paths and GND.
