8-Channel/Dual 4-Channel,
Low-Leakage, CMOS Analog Multiplexers
____________________________Features
o On-Resistance, & lt; 400Ω max
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.

MAX338/MAX339
_______________General Description
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.

maximum current ratings.
Note 1:
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 4: ∆RON = RON(MAX) - RON(MIN).
Note 5: Leakage parameters are 100% tested at the maximum rated hot temperature and guaranteed by correlation at +25°C.
Note 6: Worst-case isolation is on channel 4 because of its proximity to the drain pin. Off isolation = 20log VCOM/VNO, where

__________Applications Information
V+
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.
