MAXIM MAX362CPE

19-0180; Rev 0; 9/93
Precision, Quad, SPST Analog Switches
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 improvements guarantee extremely low charge injection
(10pC), low power consumption (35µW), and electrostatic 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.

___________Applications Information
Operation with Supply Voltages
Other Than ±15VO
Using supply voltages other than ±15V is reduces the
analog signal range. The MAX361/MAX362 switches
operate with bipolar supplies of ±4.5V to ±20V. Typical
operating characteristic graphs show typical on resistance for ±15V, ±10V, and ±5V supplies. Switching
times increase by a factor of two or more for ±5V operation. The MAX361/MAX362 can also operate from
+10V to +30V unipolar supplies. Both parts can also
be powered from unbalanced supplies such as +24V
and -5V. Connect V- to 0V when operating with a single supply.
6
Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings may cause permanent damage to the devices.
Always sequence V+ on first, followed by V-, and logic
inputs. If power-supply sequencing is not possible,
add two small signal diodes in series with the supply
pins for overvoltage protection (Figure 6). Adding the
diodes reduces the analog signal range to 1V below
V+ and 1V below V-, but low switch resistance and low
leakage characteristics are unaffected. Device operation is unchanged, and the difference from V+ to Vshould not exceed +44V.
