_______________General Description

The MAX317/MAX318/MAX319 are precision, CMOS,

monolithic analog switches. The single-pole single-

throw (SPST) MAX317 is normally closed (NC), the

SPST MAX318 is normally open (NO), and the single-

pole double-throw (SPDT) MAX319 has one normally

open and one normally closed switch. All three parts

offer low on resistance (less than 35

Ω), guaranteed to

match within 2

Ω between channels and to remain flat

over the analog signal range (

∆3Ω max). They also

offer low leakage (less than 250pA at +25°C and less

than 6nA at +85°C) and fast switching (turn-on time

less than 175ns and turn-off time less than 145ns).

The MAX317/MAX318/MAX319 are fabricated with

Maxim’s new improved silicon-gate process. Design

improvements guarantee extremely low charge injec-

tion (10pC), low power consumption (35µW), and elec-

trostatic discharge (ESD) greater than ±2000V. The

44V maximum breakdown voltage allows rail-to-rail ana-

log signal handling capability.
