The MAX4691–MAX4694 are low-voltage CMOS analog
ICs configured as an 8-channel multiplexer (MAX4691),
two 4-channel multiplexers (MAX4692), three SPDT
switches (MAX4693), and four SPDT switches
(MAX4694). All switches are bidirectional.
The MAX4691/MAX4692/MAX4693 operate from either
a single +2V to +11V power supply or dual ±2V to
±5.5V power supplies. When operating from ±5V sup-
plies they offer 25Ω on-resistance (R
R
The MAX4694 operates from a single +2V to +11V sup-
ply. Each switch has rail-to-rail signal handling, fast
switching times of t
1nA leakage current.
All digital inputs are 1.8V logic-compatible when oper-
ating from a +3V supply and TTL-compatible when
operating from a +5V supply.
The MAX4691 and MAX4692 include address pins that
allow control of the multiplexers. For the MAX4691, pins

A, B, C determine which switch is closed. The two 4-1
muxes in the MAX4692 are controlled by the same
address pins (A and B). (Table 1)
The MAX4693 and MAX4694 offer SPDT switches in
triple and quadruple packages. In the MAX4693, each
switch has a unique control input. The MAX4694 has
two digital control inputs: A (for switches “W” and “Y”)
and B (for switches “X” and “Z”). (Table 1)
The MAX4691–MAX4694 construction is typical of most
CMOS analog switches. V+ and V-* are used to drive
the internal CMOS switches and set the limits of the
analog voltage 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.
* V- is found only on the MAX4691/MAX4692/MAX4693.
