The MAX338/MAX339 are monolithic, CMOS analog
multiplexers (muxes). The 8-channel MAX338 is
designed to connect one of eight inputs to a common
output by control of a 3-bit binary address. The dual, 4channel MAX339 is designed to connect one of four
inputs to a common output by control of a 2-bit binary
address. Both devices can be used as either a mux or
a demux. On-resistance is 400Ω max, and the devices
conduct current equally well in both directions.
These muxes feature extremely low off leakages (less
than 20pA at +25°C), and extremely low on-channel
leakages (less than 50pA at +25°C). The new design
offers guaranteed low charge injection (1.5pC typ) and
electrostatic discharge (ESD) protection greater than
2000V, per method 3015.7. These improved muxes are
pin-compatible upgrades for the industry-standard
DG508A and DG509A. For similar Maxim devices with
lower leakage and charge injection but higher on-resistance, see the MAX328 and MAX329.
The MAX338/MAX339 operate from a single +4.5V to
+30V supply or from dual supplies of ±4.5V to ±20V.
All control inputs (whether address or enable) are TTL
compatible (+0.8V to +2.4V) over the full specified temperature range and over the ±4.5V to ±18V supply
range. These parts are fabricated with Maxim’s 44V silicon-gate process.

__________Applications Information
Operation with
Supply Voltages Other than 15V
Using supply voltages less than ±15V will reduce the
analog signal range. The MAX338/MAX339 switches
operate with ±4.5V to ±20V bipolar supplies or with a
+4.5V to +30V single supply. Connect V- to GND when
operating with a single supply. Both device types can
also operate with unbalanced supplies such as +24V
and -5V. The Typical Operating Characteristics graphs
show typical on-resistance with 20V, 15V, 10V, and 5V
supplies. (Switching times increase by a factor of two
or more for operation at 5V.)
Overvoltage Protection
Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings may cause permanent damage to the devices.
Always sequence V+ on first, then V-, followed by the
logic inputs NO and COM. If power-supply sequencing
is not possible, add two small signal diodes in series
with supply pins for overvoltage protection (Figure 1).
Adding diodes reduces the analog signal range to 1V
below V+ and 1V above V-, but does not affect the
devices’ low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between V+ and V- should not exceed 44V.
