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 400

Ω 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-resis-

tance, 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 tem-

perature range and over the ±4.5V to ±18V supply

range. These parts are fabricated with Maxim’s 44V sili-

con-gate process.
