ESD Protection >2000V, per Method 3015.7
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, 4-channel
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 tempera-
ture range and over the ±4.5V to ±18V supply range. These
parts are fabricated with Maxim’s 44V silicon-gate process.

Note 1:
Signals on NO, COM, EN, A0, A1, or A2 exceeding V+ or V- are clamped by internal diodes. Limit forward current to maximum
current ratings.
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.
