Product details
Overview
DG2004DQ-T1-E3 from Vishay Siliconix is a dual SPST analog switch optimized for low-voltage portable systems, featuring 1.2 Ω typical on-resistance at 5 V, 13 ns turn-on time, and 1 pC charge injection. It operates from 1.8 V to 5.5 V, supports bidirectional signal switching up to rail voltage, and is housed in an MSOP-8 package - ideal for cellular phones and battery-operated test equipment.
For engineers reviewing the DG2004DQ-T1-E3 datasheet, DG2004DQ-T1-E3 pinout, DG2004DQ-T1-E3 application, or DG2004DQ-T1-E3 equivalent, key selection criteria include low rDS(on) flatness (0.2 Ω), sub-1 nA channel leakage at 85°C, TTL/CMOS-compatible logic inputs, and guaranteed latchup immunity via epitaxial process.
Technical Context
The DG2004DQ-T1-E3 implements two independent single-pole/single-throw switches fabricated on Vishay's low-voltage JI2 CMOS process with epitaxial isolation to prevent latchup. Each switch conducts equally in both directions when ON and blocks signals up to the V+ supply level when OFF.
It uses standard digital control logic (VINH = 2.4 V min at V+ = 5 V; VINL = 0.8 V max) and delivers stable dynamic performance across temperature: tON = 13–31 ns and tOFF = 19–31 ns over –40°C to +85°C at V+ = 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic and analog rails without level shifting. |
| On-Resistance (rON) | 1.2 Ω typ @ V+ = 4.5 V - minimizes signal attenuation and distortion in precision analog paths (e.g., audio, sensor front-ends). |
| Charge Injection (QINJ) | 1 pC typ - ensures <1 LSB error in 12-bit sample-and-hold circuits with 1 nF hold capacitor. |
| Turn-On / Turn-Off Time | 13 ns / 19 ns typ @ V+ = 5 V - supports >20 MHz switching of analog waveforms in high-speed data acquisition. |
| Off-Isolation (OIRR) | –61 dB @ 1 MHz - suppresses crosstalk between adjacent channels in multi-signal routing applications. |
| Channel Leakage Current | ±1.0 nA max @ V+ = 5.5 V, 85°C - maintains accuracy in high-impedance sensor interfaces and battery monitoring. |
| Logic Compatibility | TTL/CMOS - accepts standard 3.3 V or 5 V microcontroller GPIO outputs without external buffers. |
Pinout & Package
Package: MSOP-8 (3.0 mm × 3.0 mm × 1.0 mm height), thermally enhanced, RoHS-compliant, tape-and-reel (T1-E3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO1) | Normally Open Terminal 1 | Switch output node for Channel 1; connects to COM1 when IN1 = logic high. |
| 2 (V+) | Positive Supply | Single positive rail input (1.8–5.5 V); powers analog and digital sections; must be bypassed with 0.1 µF ceramic. |
| 3 (COM1) | Common Terminal 1 | Analog signal path midpoint for Channel 1; bidirectional conduction with NO1 or NC2 depending on logic state. |
| 4 (IN1) | Channel 1 Control Input | CMOS/TTL-compatible digital input; high = connect COM1 to NO1, low = connect COM1 to NC2. |
| 5 (IN2) | Channel 2 Control Input | Independent logic input for Channel 2; identical timing and voltage thresholds as IN1. |
| 6 (COM2) | Common Terminal 2 | Second analog signal path; electrically isolated from COM1; supports separate signal routing. |
| 7 (GND) | Ground Reference | Analog and digital ground return; must be low-impedance connection to minimize noise coupling. |
| 8 (NC2) | No Connect Terminal 2 | Internally unconnected; must remain floating or tied to GND per layout best practice - no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Signal Routing | Each switch passes analog signals equally in either direction - eliminates polarity constraints in AC-coupled or differential paths. |
| Latchup Immunity | Epitaxial isolation layer prevents destructive latchup under overvoltage or ESD stress - certified per JEDEC JESD78. |
| Low rON Flatness | 0.2 Ω max over full analog range (0–V+) at V+ = 4.5 V - preserves linearity in precision gain-setting or filter-switching networks. |
| Ultra-Low Power Operation | I+ = 0.02 µA typ at V+ = 5.5 V - extends battery life in always-on sensor nodes and wearable devices. |
| Small Footprint Integration | MSOP-8 package saves >50% board area vs. SOIC-8 - critical for space-constrained mobile PCBs and modular test fixtures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4614EUA+ | Higher rON (3.5 Ω typ @ 5 V), wider V+ range (2.7–12 V), SO-8 only | Better suited for industrial 12 V systems; less optimal for 1.8 V/3.3 V portable designs | Select if higher supply voltage tolerance or SO-8 footprint compatibility is required. |
| ADG721BRMZ | Lower rON (0.8 Ω typ), but higher QINJ (3 pC), same MSOP-8, V+ = 1.8–5.5 V | Preferred for ultra-low-distortion sample-and-hold; less suitable for low-charge-injection precision multiplexing | Choose when on-resistance is primary constraint and charge injection <2 pC is not mandatory. |
Compared with MAX4614EUA+ and ADG721BRMZ, the DG2004DQ-T1-E3 uniquely balances ultra-low rON, sub-1 pC charge injection, and guaranteed latchup immunity in MSOP-8 - making it optimal for space- and power-constrained portable instrumentation where signal integrity and reliability are co-critical.

FAQ
What is the maximum analog signal voltage supported by DG2004DQ-T1-E3?
The DG2004DQ-T1-E3 supports analog signals from 0 V to V+, where V+ ranges from 1.8 V to 5.5 V. When V+ = 5.5 V, the device safely switches signals up to 5.5 V peak - including rail-to-rail audio, sensor outputs, and battery voltage taps - with no degradation in rON or leakage. Signals exceeding V+ are clamped by internal diodes; forward current must be limited to rated specifications.
Does DG2004DQ-T1-E3 require external pull-up or pull-down resistors on its IN1/IN2 pins?
No, DG2004DQ-T1-E3 does not require external pull-up or pull-down resistors on IN1 or IN2. Its TTL/CMOS-compatible inputs have defined logic thresholds (VINH ≥ 2.4 V, VINL ≤ 0.8 V at V+ = 5 V) and low input current (<1 µA), allowing direct connection to microcontroller GPIOs or FPGA outputs. Floating inputs are not recommended due to undefined switch states.
Can DG2004DQ-T1-E3 be used in bidirectional I²C or UART signal routing?
No, DG2004DQ-T1-E3 is not designed for digital bus routing like I²C or UART. It is a precision analog switch optimized for low-distortion, low-leakage analog signal paths - not open-drain or push-pull digital signaling. Using it for I²C would violate rise/fall time and capacitance requirements (CON = 110 pF, CNO(off) = 51 pF), risking communication failure.
What is the thermal resistance (θJA) of DG2004DQ-T1-E3 in MSOP-8 package?
The DG2004DQ-T1-E3 in MSOP-8 has a typical junction-to-ambient thermal resistance (θJA) of 154°C/W, based on JEDEC JESD51-7 standard mounting on 1-inch² 2-layer board with 2 oz copper. Derating is 6.5 mW/°C above 25°C ambient, supporting continuous operation up to +85°C at full 320 mW power dissipation with proper PCB copper pour.
Is DG2004DQ-T1-E3 pin-compatible with DG2003DQ-T1-E3 or DG2005DQ-T1-E3?
No, DG2004DQ-T1-E3 is not pin-compatible with DG2003DQ-T1-E3 or DG2005DQ-T1-E3. While all three share the MSOP-8 package and V+/GND pin locations, DG2004DQ-T1-E3 uses NC2 at Pin 8, whereas DG2003DQ-T1-E3 uses NO2 and DG2005DQ-T1-E3 uses NC1 - requiring distinct PCB layouts for each variant. Functional equivalence does not imply mechanical compatibility.
