Analog Switches, Multiplexers, Demultiplexers datasheet and documents for MAX4738EUD+TG51
Analog Switches, Multiplexers, Demultiplexers Overview
The MAX4738EUD+ is a quad single-pole/single-throw (SPST) analog switch operating from a single +1.8V to +5.5V supply. It features four normally closed (NC) switches with a maximum on-resistance of 4.5Ω at +3V and 3.0Ω at +5V. The device offers low leakage current (<0.5nA), high off-isolation (-55dB at 10MHz), and low crosstalk (-80dB at 10MHz). It supports rail-to-rail signal handling, break-before-make switching, and is compatible with CMOS logic levels.
Analog Switches, Multiplexers, Demultiplexers Feature Summary
- Four independent SPST switches configured as normally closed
- Low on-resistance with tight matching and flatness specifications
- Rail-to-rail signal handling capability across the full supply range
- CMOS-logic compatible inputs accepting up to +5.5V regardless of supply voltage
Analog Switches, Multiplexers, Demultiplexers Applications
- USB 1.1 signal switching
- Audio signal routing
- Data acquisition systems
- Communication equipment
Analog Switches, Multiplexers, Demultiplexers Procurement Notes
Verify the package type matches the required footprint, specifically the 14-pin TSSOP configuration. Confirm RoHS compliance status by checking for the '+' suffix in the part number. Ensure the ordering suffix aligns with the specific temperature range and packaging requirements defined in the manufacturer's official documentation.
Analog Switches, Multiplexers, Demultiplexers Selection Notes
Select this component when normally closed switching behavior is required within a quad SPST array. Compare against MAX4737 for normally open configurations or MAX4739 for mixed NO/NC setups. Evaluate the 4.5Ω on-resistance limit against system insertion loss requirements and verify compatibility with the available single-supply voltage range.
Analog Switches, Multiplexers, Demultiplexers Part Context
This device belongs to the MAX4737/MAX4738/MAX4739 family of low-voltage, low on-resistance analog switches manufactured by Analog Devices Inc./Maxim Integrated. The series provides multiple switching configurations including normally open, normally closed, and mixed states within identical pinouts and electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers FAQ
What is the default state of the switches in the MAX4738?
The MAX4738 contains four single-pole/single-throw switches that are normally closed (NC) when the logic input is low.
Can the MAX4738 handle signals exceeding its supply voltage?
No, the analog signal range is limited to the supply voltage range (V+ to GND). Signals exceeding these limits are clamped by internal diodes.
How does the MAX4738 handle logic level translation?
The logic inputs accept up to +5.5V regardless of the supply voltage, allowing mixing of logic levels in a system while operating from lower supply voltages like +3.3V.
