MAX303CSE+T

General Description
The MAX301/MAX303/MAX305 are precision, dual, high-
speed analog switches. The single-pole single-throw
(SPST) MAX301 and double-pole single-throw (DPST)
MAX305 dualswitches are normally open (NO). The sin-
gle-pole double-throw (SPDT) MAX303 has two NO and
two normally closed (NC) poles. All three parts offer low
on resistance (less than 35Ω), guaranteed to match to
within 2Ω between channels and to remain flat over the
full analog signal range (Δ3max). They also offer low leak-
age (less than 250pA at +25°C and less than 6nA at
+85°C) and fast switching (turn-on time less than 150ns
and turn-off time less than 100ns).
The MAX301/MAX303/MAX305 are fabricated with
Maxim’s new improved silicon-gate process for high
system accuracy. Design improvements guarantee
extremely low charge injection (15pC) and low power
consumption (35µW). A 44V maximum breakdown volt-
age allows rail-to-rail analog signal capability.
These monolithic switches operate with a single positive
supply (+10V to +30V) or with split supplies (±4.5V
to ±20V) while retaining CMOS-logic input compatibility
and fast switching. CMOS inputs provide reduced input
loading.

Note 1: Signals on NO_, NC_, or COM_ beyond V+ or V- are clamped by internal diodes. Limit forward current to maximum current rating.
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.
