19-0299; Rev. 6; 6/07
Precision, 8-Channel/Dual 4-Channel,
Low-Voltage, CMOS Analog Multiplexers
General Description
Features
The MAX398/MAX399 precision, monolithic, CMOS ana-
log multiplexers (muxes) offer low on-resistance (less
than 100Ω), which is matched to within 6Ω between
channels and remains flat over the specified analog sig-
nal range (11Ω max). They also offer low leakage over
temperature (NO off-leakage current less than 2.5nA at
+85°C) and fast switching speeds (transition time less
than 250ns). The MAX398 is an 8-channel device, and
the MAX399 is a dual 4-channel device.
♦ Pin Compatible with Industry-Standard
DG408/DG409/DG508A/DG509A
♦ Guaranteed On-Resistance Match
Between Channels (< 6Ω)
♦ Low On-Resistance (< 100Ω)
♦ Guaranteed Flat On-Resistance over Signal
Range (< 11Ω)
♦ Guaranteed Low Charge Injection (< 5pC)
♦ NO Off-Leakage Current < 1nA at +85°C
♦ COM Off-Leakage Current < 2.5nA at +85°C
♦ ESD Protection > 2000V
♦ +3V to +15V Single-Supply Operation
3V to 8V Bipolar-Supply Operation
♦ Low Power Consumption (< 300µW)
♦ Rail-to-Rail Signal Handling
The MAX398/MAX399 are fabricated with Maxim’s low-
voltage silicon-gate process. Design improvements yield
extremely low charge injection (less than 5pC) and guar-
antee electrostatic discharge protection (ESD) greater
than 2000V.
These muxes operate with a single +3V to +15V supply or
bipolar 3V to 8V supplies, while retaining CMOS-logic
input compatibility and fast switching. CMOS inputs pro-
vide reduced input loading. The MAX398/MAX399 are
pin compatible with the industry-standard DG408,
DG409, DG508A, and DG509A.
♦ TTL/CMOS-Logic Compatible
