8-Channel/Dual 4-Channel,
Low-Leakage, CMOS Analog Multiplexers
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.
