_______________General Description

The MAX396/MAX397 low-voltage, CMOS analog multi-

plexers (muxes) offer low on-resistance (100Ω max), which

is matched to within 6Ω between switches and remains flat

over the specified signal range (10Ω max). They also offer

low leakage over temperature (input off-leakage current

less than 1nA at +85°C) and fast switching speeds (transi-

tion time less than 250ns). The MAX396 is a 16-channel

device, and the MAX397 is a dual 8-channel device.

The MAX396/MAX397 are fabricated with Maxim’s low-

voltage silicon-gate process. Design improvements

yield extremely low charge injection (5pC max) and

guarantee electrostatic-discharge (ESD) protection

greater than 2000V per Method 3015.7

These muxes operate with a single +2.7V to +16V sup-

ply or with ±2.7V to ±8V dual supplies, while retaining

CMOS-logic input compatibility and fast switching. The

MAX396/MAX397 are pin compatible with the industry-

standard MAX306/MAX307, DG406/DG407, and

DG506A/DG507A.
