The MAX354/MAX355 fa ult-p rote c te d multip le xe rs
(muxes) use a series N-channel, P-channel, N-channel
structure that protects the devices from overvoltage up
to 40V beyond the supply rails during power-up, power-
down, and fault conditions. The MAX354/MAX355 also
protect sensitive circuit components against voltages
near or beyond the normal supplies.
♦ 350Ω Max On-Resistance
♦ Improved 2nd Source for MAX358/MAX359 and
DG458/DG459
♦ Pin Compatible with ADG508F/ADG509F
♦ All Switches Off with Supplies Off
♦ On Switch Turns Off with Overvoltage
♦ Output Clamps at 1.5V Below Supply Rails
♦ 0.5nA Max Input Leakage at +25°C (5nA at +85°C)
♦ No Power-Up Sequencing Required
♦ TTL and CMOS-Logic Compatibility
The MAX354 single 8-channel mux and the MAX355
dual 4-channel mux protect analog signals while oper-
ating from a single 4.5V to 36V supply or ±4.5V to ±18V
dual supplies. These muxes have 350Ω on-resistance
and can be used for demultiplexing as well as multi-
plexing. Input leakage current is less than 0.5nA at
+25°C and less than 5nA at +85°C.
______________Ord e rin g In fo rm a t io n
All digital inputs have 0.8V and 2.4V logic thresholds,
ensuring both TTL and CMOS logic compatibility with-
out pull-up resistors. Break-before-make operation is
g ua ra nte e d a nd p owe r c ons ump tion is le s s tha n
1.5mW.
