Product details
Overview
DG201AESE.G002 from Maxim Integrated is a quad SPST normally closed analog switch IC designed for high-voltage bipolar signal routing in precision instrumentation and test systems. It operates over ±4.5V to ±18V supplies, delivers 115Ω typical RDS(ON) at ±15V, guarantees break-before-make switching, and supports -40°C to +85°C industrial temperature range in 16-pin SO package.
For engineers reviewing the DG201AESE.G002 datasheet, DG201AESE.G002 pinout, DG201AESE.G002 application, or DG201AESE.G002 equivalent, key selection criteria include guaranteed ±15V analog signal range, sub-450ns turn-off time, no VL supply requirement, CMOS/TTL logic compatibility, and nonlatching behavior with power supplies off and input signals present.
Technical Context
The DG201AESE.G002 implements monolithic CMOS SPST switches with independent logic-controlled channels. Each switch features internal protection diodes clamping inputs to V+ and V−, and is rated for continuous operation across ±4.5V to ±18V dual supplies without latch-up under signal-present power-down conditions.
Its architecture ensures guaranteed break-before-make timing between adjacent channel transitions, with 480ns max tON and 450ns max tOFF1 at VS = 2V, RL = 1kΩ, CL = 35pF. Charge injection is limited to 20pC, enabling low-distortion sampling in data acquisition paths.
Key Specifications

FAQ
What is the maximum analog signal voltage range supported by DG201AESE.G002?
DG201AESE.G002 supports an analog signal range of ±15V when operated at ±15V supplies. Its absolute maximum ratings allow continuous operation across ±4.5V to ±18V dual supplies, enabling full-rail signal switching without clipping or distortion in industrial and test equipment applications.
Does DG201AESE.G002 require a third VL supply voltage like some legacy analog switches?
No, DG201AESE.G002 does not require a third VL supply. Unlike the original DG211, Maxim eliminated the VL rail requirement - simplifying power design and reducing component count. DG201AESE.G002 operates fully with only V+, V−, and GND connections.
What is the guaranteed switching timing performance of DG201AESE.G002 at industrial temperatures?
DG201AESE.G002 guarantees a maximum turn-off time (tOFF1) of 450ns and maximum turn-on time (tON) of 600ns over its full -40°C to +85°C operating range, measured at VS = 2V, RL = 1kΩ, and CL = 35pF - ensuring consistent high-speed multiplexing in demanding environments.
How does DG201AESE.G002 behave when power supplies are disconnected but analog signals remain present?
DG201AESE.G002 is nonlatching: it will not conduct or enter undefined states when V+ and V− are removed while analog signals are still applied to S or D pins. This fault-tolerant behavior prevents unintended signal coupling and meets safety requirements in military and avionics systems.
What package type and lead finish does DG201AESE.G002 use?
DG201AESE.G002 is supplied in a 16-pin SO (Small Outline) package with standard gull-wing leads and matte tin (Sn) lead finish, compliant with JEDEC MS-012 specifications and RoHS 2011/65/EU. The package measures 10.0mm × 4.4mm × 1.75mm and supports reflow soldering per IPC/JEDEC J-STD-020.
