_______________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

Ω (max), and the devices

conduct current equally well in both directions.

These muxes feature extremely low off leakages (less

than 20pA at +25°C) and on-channel leakages (less than

50pA at +25°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 ±4.5V to ±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 ±4.5V to ±18V supply range.
