8-Channel/Dual 4-Channel,  
Low-Leakage, CMOS Analog Multiplexers  
8/MAX39  
____________________________Features  
o On-Resistance, <400Ω max  
o Transition Time, <500ns  
o On-Resistance Match, <10Ω  
o NO-Off Leakage Current, <20pA at +25°C  
o 1.5pC Charge Injection  
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 400max, and the devices  
conduct current equally well in both directions.  
o Single-Supply Operation (+4.5V to +30V)  
Bipolar-Supply Operation ( 4.5V to 20V)  
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.  
o Plug-In Upgrade for Industry-Standard  
DG508A/DG509A  
o Rail-to-Rail Signal Handling  
o TTL/CMOS-Logic Compatible  
o ESD Protection >2000V, per Method 3015.7

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.
