_______________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.
