Precision, 8-Channel/Dual 4-Channel,

High-Performance, CMOS Analog Multiplexers

_______________General Description

The MAX308/MAX309 precision, monolithic, CMOS ana­log multiplexers (muxes) offer low on-resistance (less
than 100Ω), which is matched to within 5Ω between
channels and remains flat over the specified analog sig­nal range (7Ω max). They also offer low leakage over
temperature (NO-off leakage current less than 5nA at
+85°C) and fast switching speeds (transition time less
than 250ns). The MAX308 is a single-ended 1-of-8
device, and the MAX309 is a differential 2-of-4 device.

The MAX308/MAX309 are fabricated with Maxim’s
improved 44V silicon-gate process. Design improve­ments yield extremely low charge injection (less than
10pC) and guarantee electrostatic discharge protection
greater than 2000V.

These muxes operate with a single +4.5V to +30V sup­ply or bipolar ±4.5V to ±20V supplies, while retaining
TTL/CMOS-logic input compatibility and fast switching.
CMOS inputs provide reduced input loading. These
improved parts are plug-in upgrades for the industry­standard DG408, DG409, DG508A, and DG509A.

Note 1: Signals on NO, COM, EN, A0, A1, or A2 exceeding V+ or V- are clamped by internal diodes. 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.
