16-Channel/Dual 8-Channel,
Low-Leakage, CMOS Analog Multiplexers
_______________General Description
The MAX336/MAX337 are monolithic, CMOS analog
multiplexers (muxes). The 16-channel MAX336 is
designed to connect one of 16 inputs to a common out-
put by control of a 4-bit binary address. The dual,
8-channel MAX337 is designed to connect one of eight
inputs to a common output by control of a 3-bit binary
address. Both devices can be used as either a mux or
a demux. On-resistance is 400鈩?(max), and the devices
conduct current equally well in both directions.
These muxes feature extremely low off leakages (less
than 20pA at +25擄C) and on-channel leakages (less than
50pA at +25擄C). The new design offers guaranteed low
charge injection (3.5pC typical) and electrostatic dis-
charge (ESD) protection greater than 2000V, per method
3015.7. These improved muxes are pin-compatible
upgrades for the industry-standard DG506 and DG507.
The MAX336/MAX337 operate from a single +4.5V to
+30V supply or from dual 鹵4.5V to 鹵20V supplies. All
control inputs (whether address or enable) are TTL
compatible (0.8V to 2.4V) over the full specified temper-
ature range and over the 鹵4.5V to 鹵18V supply range.
