_______________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

When powered from a 5V supply, the MAX323 series

offers 2

Ω max matching between channels, 60Ω max

on-resistance, and 6

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.
