Precision, Quad, SPST Analog Switches
General Description
____________________________Features
♦ Low On Resistance: < 45Ω Typical (85Ω Max)
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).
♦ Guaranteed Matched On-Resistance Between Channels: < 2Ω
♦ Guaranteed Flat On-Resistance over Analog Signal
Range: ∆9Ω Max
♦ Guaranteed Charge Injection: < 10pC
♦ Guaranteed Off-Channel Leakage: <4nA at +85°C
♦ ESD Guaranteed > 2000V per Method 3015.7
♦ Single-Supply Operation (+10V to +30V)
Bipolar-Supply Operation ( 4.5V to 20V)
♦ TTL-/CMOS-Logic Compatible
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.
