Product details
Overview
DG2511DN-T1-E4 from Vishay Siliconix is a low-voltage, single-pole/double-throw (SPDT) monolithic CMOS analog switch in miniQFN-6 package, featuring 1.3 Ω on-resistance at 2.7 V, guaranteed break-before-make switching, and operation from 1.8 V to 5.5 V supply - ideal for signal routing in portable battery-powered systems such as cellular handsets and ADC front-ends.
For engineers reviewing the DG2511DN-T1-E4 datasheet, DG2511DN-T1-E4 pinout, DG2511DN-T1-E4 application, or DG2511DN-T1-E4 equivalent, key selection considerations include its 1.3 Ω RON at 2.7 V, 3 pC charge injection, 18 ns turn-on time, and miniQFN-6 (1.2 × 1.0 mm) footprint for space-constrained designs.
Technical Context
The DG2511DN-T1-E4 implements a CMOS transmission gate architecture with epitaxial latch-up protection and rail-to-rail analog signal handling (0 V to V+). Its control logic accepts TTL/CMOS-compatible inputs (VINH = 1.6 V min at V+ = 3 V), enabling direct interfacing with 1.8 V and 3.3 V microcontrollers without level shifting.
Break-before-make timing is guaranteed (tBBM ≥ 1 ns), preventing momentary shorting between NC and NO paths during switching. The device operates across –40 °C to +85 °C with <20 nA off-leakage and 61 pF channel-on capacitance - supporting precision sample-and-hold and low-distortion data acquisition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct interface with 1.8 V, 2.7 V, 3.3 V, and 5 V logic/system rails |
| On-Resistance (RON) | 1.3 Ω typ. at V+ = 2.7 V, VCOM = 0.5 V/1.5 V - minimizes signal attenuation and voltage drop in low-level analog paths |
| Charge Injection | 3 pC max. - reduces settling error in high-impedance sampling nodes (e.g., ADC input hold capacitors) |
| Turn-On Time (tON) | 18 ns typ. at V+ = 2.7 V, RL = 50 Ω, CL = 35 pF - enables fast multiplexing in multi-channel data acquisition |
| Off-Leakage Current | ±20 nA max. at V+ = 3.3 V - preserves accuracy in µA-range sensor interfaces and battery-monitoring circuits |
| Package | miniQFN-6 (1.2 mm × 1.0 mm, 0.4 mm pitch) - delivers ultra-compact footprint with exposed thermal pad for PCB heat dissipation |
Pinout & Package
Package: miniQFN-6 (1.2 × 1.0 mm body, 0.4 mm pitch, exposed thermal pad per Vishay Document 74497). Pin 1 marked with long lead; top-side marking "Ax" (x = date/lot code).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital control input | Active-high logic input; drives internal CMOS switch gates; compatible with 1.8 V logic thresholds |
| 2 (GND) | Ground reference | Analog and digital ground common node; must be connected to system ground plane for noise immunity |
| 3 (COM) | Common analog terminal | Center pole of SPDT switch; bidirectional signal path with symmetric RON and capacitance |
| 4 (NC) | Normally closed analog terminal | Connected to COM when IN = 0 V; isolated from COM when IN = V+ |
| 5 (V+) | Positive supply rail | Provides power for internal bias circuitry and defines analog signal range (0 V to V+) |
| 6 (NO) | Normally open analog terminal | Connected to COM when IN = V+; isolated from COM when IN = 0 V; break-before-make guaranteed |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance | 1.3 Ω at 2.7 V enables <10 mV drop at 100 mA - critical for precision current-sense and audio signal routing |
| Guaranteed break-before-make | tBBM ≥ 1 ns prevents cross-conduction between NC and NO paths - essential for avoiding signal shorts in multiplexer arrays |
| Ultra-low charge injection | 3 pC limits voltage glitch on 1 nF sampling capacitors to <3 mV - maintains 12-bit+ accuracy in SAR ADC front-ends |
| Rail-to-rail analog range | Supports signals from 0 V to V+ (up to 5.5 V) - eliminates need for external clamping diodes in most applications |
| Latch-up immunity | Epitaxial process ensures >300 mA latch-up immunity (JESD78A) - enhances reliability in noisy industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Texas Instruments TS5A23157DCUR | RON = 0.9 Ω at 3.3 V; 5-pin SC70 package; no exposed thermal pad | Higher RON flatness (0.1 Ω) but larger 2.0 × 1.25 mm footprint and no latch-up immunity spec | Prefer for lowest RON in non-latch-up-critical 3.3 V systems where thermal performance is secondary |
| Analog Devices ADG858BRMZ | RON = 0.6 Ω at 3 V; 10-lead MSOP; requires 1.65–5.5 V supply | Lower RON but 3× larger area (3.0 × 3.0 mm); higher 15 pC charge injection | Choose when sub-1 Ω RON justifies larger PCB area and higher cost; not suitable for ultra-compact wearables |
Compared with TS5A23157DCUR and ADG858BRMZ, the DG2511DN-T1-E4 offers the smallest footprint (1.2 × 1.0 mm), guaranteed break-before-make, and latch-up immunity - making it optimal for space- and reliability-constrained portable medical and test equipment.

FAQ
What is the maximum analog signal voltage range supported by the DG2511DN-T1-E4?
The DG2511DN-T1-E4 supports analog signals from 0 V to V+, where V+ ranges from 1.8 V to 5.5 V. For example, with V+ = 3.3 V, the full analog range is 0 V to 3.3 V. Signals exceeding V+ are clamped by internal diodes, so the absolute maximum analog voltage is V+ + 0.3 V per Absolute Maximum Ratings.
Does the DG2511DN-T1-E4 require external pull-up or pull-down resistors on the IN pin?
No, the DG2511DN-T1-E4 does not require external pull-up or pull-down resistors on the IN pin. Its input threshold is TTL/CMOS-compatible (VINL ≤ 0.4 V, VINH ≥ 1.6 V at V+ = 3 V), and input leakage is only ±1 µA - allowing direct connection to microcontroller GPIOs without additional biasing components.
Is the DG2511DN-T1-E4 pin-compatible with other devices in the DG251x family?
No, the DG2511DN-T1-E4 is not pin-compatible with DG2512DN-T1-E4 or DG2513DN-T1-E4. While all three share the same miniQFN-6 package, their pinouts differ: DG2511 has IN/ GND/ COM/ NC/ V+/ NO; DG2512 uses IN/ GND/ COM/ NC/ V+/ NC; DG2513 uses IN/ GND/ COM/ NO/ V+/ NO - requiring unique PCB layouts for each variant.
What thermal performance can be expected from the DG2511DN-T1-E4 in continuous operation?
The DG2511DN-T1-E4 has a maximum power dissipation of 160 mW in the miniQFN-6 package. With a thermal derating of 2 mW/°C above 70 °C, usable power drops to ~140 mW at 85 °C ambient. Proper PCB copper pour under the exposed thermal pad is required to maintain junction temperature within –40 °C to +125 °C limits.
How does the DG2511DN-T1-E4 handle bidirectional analog signal flow?
The DG2511DN-T1-E4 conducts equally well in both directions when ON due to its symmetrical CMOS transmission gate structure. RON, capacitance, and leakage are matched between COM→NC and NC→COM paths, enabling true bidirectional signal routing - essential for audio, sensor, and instrumentation applications where signal polarity is undefined.
