Precision, Quad, SPST Analog Switches
General Description
The MAX361/MAX362 are precision, quad, single-pole
single-throw (SPST) analog switches. The MAX361 has four
normally closed (NC) switches, and the MAX362 has four
normally open (NO) switches. Both parts offer low channel
on-resistance (less than 85Ω), guaranteed to match within
3Ω between channels and to remain flat over the analog
signal range (∆9Ω max). Both parts also offer low leakage
(less than 500pA at +25°C and less than 4nA at +85°C) and
fast switching (turn-on time less than 250ns and turn-off time
less than 170ns).
The MAX361/MAX362 are fabricated with Maxim’s new
improved 44V silicon-gate process. Design improve-
ments guarantee extremely low charge injection
(10pC), low power consumption (35µW), and electro-
static discharge (ESD) greater than 2000V. The 44V
maximum breakdown voltage allows rail-to-rail analog
signal handling 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.

All leads are soldered or welded to PC board.
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.
