MAX321CSA+

P1-P3P4-P6P7-P8
_______________General Description
The MAX320/MAX321/MAX322 are precision, dual,
SPST analog switches designed to operate from ±3V to
±8V dual supplies. The MAX320 has two normally open
(NO) switches and the MAX321 has two normally
closed (NC) switches. The MAX322 has one NO and
one NC switch. Low power consumption (1.25mW)
makes these parts ideal for battery-powered equip-
ment. They offer low leakage currents (100pA max) and
fast switching speeds (t
ON
= 150ns max, t
OFF
= 100ns
max).
The MAX320 series, powered from ±5V supplies, offers
35Ω max on-resistance (R
ON
), 2Ω max matching
between channels, and 4Ω max R
ON
flatness.
These switches also offer 5pC max charge injection
and a minimum of 2000V ESD protection per Method
3015.7.
For equivalent devices specified for single-supply oper-
ation, see the MAX323/MAX324/MAX325 data sheet.
For quad versions of these switches, see the
MAX391/MAX392/MAX393 data sheet.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ABSOLUTE MAXIMUM RATINGS
Note 1: Signals on NC_, NO_, COM_, or IN_ exceeding V+ or V- are clamped by internal diodes. Limit forward diode current to
maximum current rating.
