Low-Voltage, 8-Channel/Dual 4-Channel
Multiplexers with Latchable Inputs
_______________General Description
The MAX382/MAX384 are low-voltage, CMOS, 1-of-8
and dual 4-channel muxes with latchable digital inputs.
They feature low-voltage operation from a +2.7V to
+16.5V single supply and from ±3V to ±8V dual sup-
plies. Pin compatible with the DG428/DG429, these
muxes offer low on-resistance (100Ω max) matched to
within 4Ω max between channels. Additional features
include off leakage less than 2.5nA at +85°C and guar-
anteed low charge injection (10pC max). ESD protec-
tion is greater than 2000V per Method 3015.7.

Note 1:
Signals on any terminal 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.

The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in this data sheet.
Guaranteed by design.
∆R
ON
= R

(max) - R

(min).
Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog signal
ranges, i.e., V
NO
= 3V to 0V and 0V to -3V.
Note 6:
Leakage parameters are 100% tested at maximum rated hot operating temperature, and guaranteed by correlation at +25°C.
Note 7:
Worst-case isolation is on channel 4 because of its proximity to the COM pin. Off isolation = 20log V
COM
/V
NO
, V
COM
= output, V
NO
= input to off switch.
Note 8:
Leakage testing at single supply is guaranteed by correlation testing with dual supplies.
