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.
____________________________Features
o Pin-Compatible with Industry-Standard
DG428/DG429, DG528/DG529, MAX368/MAX369
o Single-Supply Operation (+2.7V to +16.5V)
Bipolar Supply Operation (±3V to ±8V)
o Low Power Consumption (<300µW)
o Low On-Resistance, 100Ω max
o Guaranteed On-Resistance Match Between
Channels, 4Ω max
o Low Leakage, 2.5nA at +85°C
o TTL/CMOS-Logic Compatible

Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in this data sheet.
Note 3: Guaranteed by design.
Note 4: ∆RON = RON(max) - RON(min).
Note 5: 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., VNO = 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 VCOM/VNO, VCOM = output, VNO = input to off switch.
Note 8: Leakage testing at single supply is guaranteed by correlation testing with dual supplies.
