MAXIM MAX312, MAX313, MAX314 Technical data

General Description

Maxim’s MAX312/MAX313/MAX314 analog switches
feature low on-resistance (10Ω max) and 1.5Ω on-resis­tance matching between channels. These switches con­duct equally well in either direction. They offer low
leakage over temperature (2.5nA at +85°C). Low power
consumption and ESD tolerance greater than 2000V per
Method 3015.7 are guaranteed.

The MAX312/MAX313/MAX314 are quad, single­pole/single-throw (SPST) analog switches. The MAX312
is normally closed (NC), and the MAX313 is normally
open (NO). The MAX314 has two NC switches and two
NO switches. All three devices operate from a single
supply of +4.5V to +30V or from dual supplies of ±4.5V
to ±20V.

this data sheet.

Note 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the

specified analog signal range.

Note 6: Leakage parameters are 100% tested at maximum-rated hot temperature and guaranteed by correlation at +25°C.
