MAX338/MAX339 19-0272 Rev 3 11/04 8-Channel/Dual 4-Channel, Low-Leakage, CMOS Analog Multiplexers Features General Description The MAX338/MAX339 are monolithic, CMOS analog On-Resistance, <400 max multiplexers (muxes). The 8-channel MAX338 is Transition Time, <500ns designed to connect one of eight inputs to a common output by control of a 3-bit binary address. The dual, 4- On-Resistance Match, <10 channel MAX339 is designed to connect one of four NO-Off Leakage Current, <20pA at +25C inputs to a common output by control of a 2-bit binary 1.5pC Charge Injection address. Both devices can be used as either a mux or a demux. On-resistance is 400 max, and the devices Single-Supply Operation (+4.5V to +30V) conduct current equally well in both directions. Bipolar-Supply Operation (4.5V to 20V) These muxes feature extremely low off leakages (less Plug-In Upgrade for Industry-Standard than 20pA at +25C), and extremely low on-channel DG508A/DG509A leakages (less than 50pA at +25C). The new design offers guaranteed low charge injection (1.5pC typ) and Rail-to-Rail Signal Handling electrostatic discharge (ESD) protection greater than TTL/CMOS-Logic Compatible 2000V, per method 3015.7. These improved muxes are pin-compatible upgrades for the industry-standard ESD Protection >2000V, per Method 3015.7 DG508A and DG509A. For similar Maxim devices with Ordering Information lower leakage and charge injection but higher on-resis- tance, see the MAX328 and MAX329.

Limit forward current to maximum current ratings. 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.
