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, 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.
