Product details
Overview
DG417LEUA from Maxim Integrated is a precision CMOS single-pole/single-throw (SPST) analog switch with normally closed (NC) configuration, 35Ω max on-resistance, ±4.5V to ±20V dual-supply or +9V to +36V single-supply operation, and +3V logic-compatible digital inputs (VIH = 2.0V, VIL = 0.8V). It delivers rail-to-rail analog signal handling, <5nA off-leakage at +85°C, and sub-175ns turn-on time-ideal for battery-operated test equipment requiring low-power, high-accuracy signal routing.
For engineers reviewing the DG417LEUA datasheet, DG417LEUA pinout, DG417LEUA application, or DG417LEUA equivalent, key selection considerations include its guaranteed 3Ω max RON matching, 4Ω max RON flatness over signal range, -40°C to +85°C extended temperature rating, µMAX-8 package footprint, and compatibility with TTL/CMOS logic without level-shifting.
Technical Context
The DG417LEUA implements a fully differential CMOS transmission-gate architecture enabling bidirectional conduction, low charge injection (15pC), and minimal THD (0.002% at 20Hz–20kHz). Its logic interface operates independently of supply sequencing-eliminating latch-up risk during power-up across ±4.5V to ±20V or +9V to +36V rails.
It supports rail-to-rail analog signals from V− to V+, maintains <6Ω on-resistance flatness under ±10V signal swing (dual supply), and achieves >90dB off-isolation at 1MHz. The device is characterized for guaranteed performance across -40°C to +85°C with 100% hot-temperature leakage testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 35Ω max - ensures minimal voltage drop and signal attenuation in precision analog paths |
| RON matching | 3Ω max - enables matched gain/attenuation in differential or multi-channel switching applications |
| RON flatness | 4Ω max - maintains consistent channel resistance across full analog input range (V− to V+) |
| Off-leakage current | <5nA at +85°C - preserves accuracy in high-impedance sample-and-hold or sensor front-ends |
| Turn-on time (tON) | <175ns - supports fast multiplexing in automated test equipment and real-time signal routing |
| Logic thresholds | VIH = 2.0V, VIL = 0.8V - guarantees reliable +3V TTL/CMOS compatibility without external biasing |
| Analog signal range | Rail-to-rail (V− to V+) - allows full utilization of supply headroom in bipolar or single-supply systems |
Pinout & Package
Package: 8-pin µMAX (3mm × 3mm, 0.5mm pitch), RoHS-compliant, surface-mount, thermal pad exposed on bottom.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 COM | Analog common terminal | Input/output node connected to NC path when IN = 0; electrically isolated when IN = 1 |
| 2 N.C. | No connection | Internally unconnected; must be left floating or tied to GND per layout best practice |
| 3 GND | Digital logic ground reference | Reference for logic input thresholds; separate from analog supply grounds but typically tied at single point |
| 4 V+ | Positive analog supply | Supports +9V to +36V single supply or +4.5V to +20V in dual-supply mode; defines upper analog rail |
| 6 IN | Logic control input | +3V-compatible digital input; active-low logic sense (IN = 0 → NC closed; IN = 1 → NC open) |
| 7 V− | Negative analog supply | Supports −4.5V to −20V in dual-supply mode; defines lower analog rail; may be 0V in single-supply use |
| 8 NC | Normally closed analog terminal | Closed to COM when IN = 0; opens when IN = 1; no internal connection to other pins |
Key Features
| Feature | Design Value |
|---|---|
| +3V logic compatibility | VIH = 2.0V / VIL = 0.8V thresholds eliminate need for level shifters when interfacing with modern microcontrollers |
| Power-supply sequencing freedom | No required V+/V−/GND power-up order-prevents latch-up without external diodes or sequencing circuitry |
| Rail-to-rail signal handling | Full V− to V+ analog range support enables use in ±15V industrial instrumentation and +24V PLC I/O modules |
| Low charge injection | 15pC typical - minimizes voltage glitch in sample-and-hold circuits and ADC front-ends |
| Guaranteed leakage spec | <5nA off-leakage at +85°C - validated 100% at max temperature, ensuring reliability in harsh environments |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUA+ | Lower RON (15Ω typ), higher supply current (30µA), same µMAX-8 package and -40°C to +85°C rating | Better for low-distortion audio routing; less suitable for ultra-low-power battery systems | Select MAX4617EUA+ when RON <20Ω is critical and supply current budget allows ~3× increase |
| ADG1419BRMZ | SPDT configuration (NC/NO), 1.8V logic compatible, 4.5Ω RON, SOIC-10 package, +125°C rating | Requires PCB redesign (SOIC-10 vs µMAX-8); suited for automotive under-hood use where extended temp is mandatory | Choose ADG1419BRMZ only if SPDT function, 1.8V logic, or +125°C operation is required-and layout change is acceptable |
Compared with DG417LEUA, MAX4617EUA+ trades lower on-resistance for higher quiescent current, while ADG1419BRMZ offers wider temperature range and SPDT functionality at the cost of larger footprint and different logic voltage compatibility-neither is pin-compatible, and both require schematic and layout review.

FAQ
What is the maximum allowable analog signal voltage range for DG417LEUA?
The DG417LEUA supports rail-to-rail analog signals from V− to V+. With ±15V supplies, this spans −15V to +15V; with +12V single supply (V− = 0V), it handles 0V to +12V. Absolute maximum ratings limit VCOM, NC, or NO to (V− − 0.3V) to (V+ + 0.3V), so staying within V− to V+ ensures safe, specified operation. DG417LEUA maintains guaranteed RON flatness and leakage specs across this full range.
Does DG417LEUA require specific power-supply sequencing during startup?
No-DG417LEUA features power-supply sequencing-free operation. Unlike earlier DG417 variants, it eliminates latch-up risk regardless of V+, V−, or GND power-up order. This simplifies system design and removes the need for external protection diodes. DG417LEUA remains functional and within specifications even if V− rises before V+ or GND is established, provided absolute maximum ratings are not exceeded.
Can DG417LEUA operate with a +3.3V logic supply while using ±15V analog supplies?
Yes. DG417LEUA's digital input is +3V logic-compatible with VIH = 2.0V and VIL = 0.8V, making it fully interoperable with +3.3V CMOS/TTL logic. Its logic interface is referenced to GND and independent of analog supply voltages, so +3.3V control signals work reliably with ±15V (or ±12V, ±20V) analog rails. DG417LEUA does not require level translation in mixed-voltage systems.
What is the guaranteed on-resistance matching specification for DG417LEUA?
DG417LEUA is a single-channel SPST switch, so on-resistance matching between channels does not apply. That parameter (ΔRON ≤ 3Ω max) is specified only for the DG419L SPDT variant, which integrates two switches on one die. DG417LEUA guarantees absolute RON ≤ 45Ω over temperature and RON flatness ≤ 6Ω-critical for maintaining signal integrity in precision analog paths where resistance variation causes gain error.
Is the µMAX-8 package of DG417LEUA lead-free and RoHS compliant?
Yes. DG417LEUA in the 8-pin µMAX package (order code DG417LEUA) is manufactured with lead-free terminations and complies with EU RoHS Directive 2011/65/EU. The package uses matte tin plating over copper leads, and Maxim's official documentation confirms full exemption-free compliance. DG417LEUA supports standard Pb-free reflow profiles and is suitable for environmentally regulated industrial and defense applications.
