MAXIM MAX338, MAX339 Technical data

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.

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.
