19-0185; Rev 1; 11/94 Precision, CMOS Analog Switches _______________General Description The MAX317/MAX318/MAX319 are precision, CMOS, monolithic analog switches.
The single-pole singlethrow (SPST) MAX317 is normally closed (NC), the SPST MAX318 is normally open (NO), and the singlepole double-throw (SPDT) MAX319 has one normally open and one normally closed switch.
All three parts offer low on resistance (less than 35Ω), guaranteed to match within 2Ω 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).
