MAX323/MAX324/MAX325
_______________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 consumption (5µW) makes these parts ideal for battery-powered
equipment. These switches offer low leakage currents
(100pA max) and fast switching speeds (tON = 150ns
max, tOFF = 100ns max).
When powered from a 5V supply, the MAX323 series
offers 2Ω max matching between channels, 60Ω max
on-resistance, and 6Ω max RON 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 operation, see the MAX320/MAX321/MAX322 data sheet. For
quad versions of the MAX320 series, see MAX391/
MAX392/MAX393 data sheet.
