_______________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
max, t
= 100ns max).
OFF
When powered from a 5V supply, the MAX323 series
offers 2Ω max matching between channels, 60Ω max
on-resistance, and 6Ω max R
flatness.
ON
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.

... V+ Positive Supply __________Applications Information The MAX323/MAX324/MAX325 are TTL compatible when powered from a single +5V supply. When pow- ered from other supply voltages, TTL compatibility is not guaranteed, and the logic inputs should be driven from rail to rail. For example, with a 15V supply, IN1 and IN2 should be driven low to 0V and high to 15V ...
