MAX353CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX353CSE is a precision, quad, single-pole single-throw (SPST) analog switch featuring two normally open and two normally closed channels. It operates with a single positive supply (+10V to +30V) or split supplies (±4.5V to ±20V). The device offers low on resistance of less than 35Ω, guaranteed to match within 2Ω between channels. It provides fast switching with turn-on time less than 175ns and turn-off time less than 145ns. The component supports rail-to-rail analog signal handling and includes electrostatic discharge protection greater than 2000V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CSE' to confirm the narrow SOIC package and commercial temperature range (0°C to +70°C). Ensure the logic supply voltage aligns with TTL or CMOS requirements as specified in the datasheet. Confirm that the application environment remains within the absolute maximum ratings for power dissipation and signal voltages.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a mix of normally open and normally closed analog switching paths is required within a single package. Verify that the system power supply falls within the +10V to +30V single-supply or ±4.5V to ±20V dual-supply ranges. Consider the 35Ω maximum on resistance and leakage currents for signal integrity requirements in the target circuit design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX351/MAX352/MAX353 family of precision analog switches. While the MAX351 contains four normally closed switches and the MAX352 contains four normally open switches, the MAX353 specifically integrates two of each type. All variants share identical electrical characteristics and fabrication processes.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX351CSE and MAX352CSE, which offer different switch states but identical electrical performance and packaging.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX351, MAX352, and MAX353?

The MAX351 contains four normally closed (NC) switches, the MAX352 contains four normally open (NO) switches, and the MAX353 contains two NO and two NC switches.

Can the MAX353 operate with unbalanced power supplies?

Yes, the device can be powered from unbalanced supplies such as +24V and -5V, provided the difference between V+ and V- does not exceed +44V.

How is the logic supply voltage configured for TTL compatibility?

To achieve TTL compatibility, the VL pin must be connected to +5V. For CMOS-logic input levels, it should be connected to V+.
