_______________General Description
The MAX323/MAX324/MAX325 are precision, dual,
SPST analog switches. They are single-supply devices
designed to operate from +2.7V to +16V. The MAX323
has two normally open (NO) switches, and the MAX324
has two normally closed (NC) switches. The MAX325
has one NO and one NC switch. Low power consump-
tion (5µW) makes these parts ideal for battery-powered
equipment. These switches offer low leakage currents
(100pA max) and fast switching speeds (t
ON
= 150ns
max, t
OFF
= 100ns max).
When powered from a 5V supply, the MAX323 series
offers 2Ω max matching between channels, 60Ω max
on-resistance, and 6Ω max R
ON
flatness.
These switches also offer 5pC max charge injection,
and a minimum of 2000V ESD per Method 3015.7.
For equivalent devices specified for dual-supply opera-
tion, see the MAX320/MAX321/MAX322 data sheet. For
quad versions of the MAX320 series, see 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.
