Product details
Overview
DGQ4051EEQ-T1-GE4 from Vishay Siliconix is an 8-channel single-pole, single-throw (8:1) analog multiplexer IC designed for high-precision signal routing in automotive and industrial systems. It features 68 Ω typical on-resistance at ±5 V dual supply, <0.3 pC charge injection, 2.2 pF source-off capacitance, and operates across -40 °C to +125 °C - enabling rail-to-rail switching in battery management and sensor signal conditioning.
For engineers reviewing the DGQ4051EEQ-T1-GE4 datasheet, DGQ4051EEQ-T1-GE4 pinout, DGQ4051EEQ-T1-GE4 application, or DGQ4051EEQ-T1-GE4 equivalent, key selection criteria include guaranteed 3 V logic compatibility, AEC-Q100 Grade 1 qualification, low leakage (<50 pA), fast enable turn-on time (35 ns typ.), and TSSOP16 package compatibility with space-constrained PCB layouts.
Technical Context
The DGQ4051EEQ-T1-GE4 implements a CMOS transmission-gate architecture with break-before-make switching control, supporting bidirectional analog signal flow across its eight input channels to one common output. Its digital control interface accepts 3 V–5 V logic levels and includes an active-low ENABLE pin that forces all switches open when high.
It is fully specified for operation from ±3 V to ±8 V dual supplies or 3 V to 16 V single supplies, with guaranteed performance at 3 V, 5 V, 12 V, and ±5 V. All analog terminals tolerate signals beyond supply rails via internal clamping diodes, subject to forward current limits.
Key Specifications

|---|---|
| Analog Configuration | 8:1 single-pole, single-throw (SPST) multiplexer - selects one of eight analog inputs to common output |
| On-Resistance (RON) | 68 Ω typ. at ±5 V - ensures minimal signal attenuation and voltage drop in precision measurement paths |
| Charge Injection | 0.3 pC max over full voltage range - prevents DC offset errors in sample-and-hold and ADC front-end circuits |
| Source-Off Capacitance (CS(OFF)) | 2.2 pF typ. - reduces crosstalk and maintains high-frequency signal integrity during channel switching |
| Enable Turn-On Time (tON) | 35 ns typ. at ±5 V - enables rapid channel reconfiguration in real-time data acquisition systems |
| Operating Temperature | -40 °C to +125 °C - supports under-hood automotive and industrial environments without derating |
| Supply Range | 3 V to 16 V single supply or ±3 V to ±8 V dual supply - accommodates legacy 5 V, modern 3.3 V, and high-voltage 12 V systems |

Applications
| Automotive Battery Management System (BMS) | Industrial Sensor Signal Multiplexing |
|---|---|
Use Scenario: Monitoring cell voltages across 8-series lithium-ion battery packs using a single ADC channel. IC Role / Device Role / Timing Role: High-precision analog multiplexer routing individual cell voltages to ADC input while maintaining low offset and crosstalk. Use Value: 0.3 pC charge injection prevents integration error in sample-and-hold stages; 2.2 pF CS(OFF) minimizes inter-cell interference during scanning. | Use Scenario: Consolidating analog outputs from multiple temperature, pressure, and current sensors into one data acquisition unit. IC Role / Device Role / Timing Role: Low-leakage (≤50 pA), rail-to-rail SPST switch enabling accurate DC-coupled signal routing without gain/offset drift. Use Value: 68 Ω RON ensures <0.1% gain error in 10 kΩ sensor bridge configurations; -40 °C to +125 °C rating supports uncooled industrial enclosures. |
| Automotive Infotainment Audio Routing | Test & Measurement Equipment Channel Selection |
Use Scenario: Dynamically selecting between multiple microphone or line-level audio sources in head-unit systems. IC Role / Device Role / Timing Role: Low-distortion (0.065% THD), wide-bandwidth (308 MHz) analog switch handling audio-frequency signals with minimal phase shift. Use Value: 308 MHz 3 dB bandwidth preserves fidelity up to ultrasonic harmonics; low crosstalk (-105 dB @ 100 kHz) prevents source bleed in multi-input mixing. | Use Scenario: Automated test equipment requiring fast, repeatable channel switching between DUTs and measurement instruments. IC Role / Device Role / Timing Role: Sub-100 ns enable timing (tON = 35 ns typ.) synchronized to system clock for deterministic scan sequencing. Use Value: Break-before-make delay (tD ≤ 1 ns) eliminates transient short-circuits during reconfiguration; AEC-Q100 qualification ensures long-term reliability in production testers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | 8:1 mux with 45 Ω RON (±5 V), but only rated to +85 °C and not AEC-Q100 qualified | Lacks automotive temperature and reliability validation; suitable for commercial-grade instrumentation only | Select when cost sensitivity outweighs automotive qualification requirements |
| ADG1408BRUZ | 8:1 mux with 4.5 Ω RON (±5 V), but higher charge injection (1.5 pC) and larger 16-lead TSSOP footprint (5.0 mm × 4.4 mm vs. 4.4 mm × 5.0 mm) | Better RON for low-impedance loads, but unsuitable for precision sampling due to higher charge injection | Select when ultra-low on-resistance is critical and charge injection can be compensated externally |
Compared with MAX4617ESE+ and ADG1408BRUZ, the DGQ4051EEQ-T1-GE4 uniquely balances AEC-Q100 Grade 1 compliance, sub-0.3 pC charge injection, and 68 Ω RON in a compact TSSOP16 - making it optimal for automotive BMS and industrial sensor hubs where accuracy, reliability, and temperature resilience are jointly required.

FAQ
What is the maximum supply voltage rating for DGQ4051EEQ-T1-GE4?
The DGQ4051EEQ-T1-GE4 has an absolute maximum V+ to V− rating of +18 V. It operates reliably across 3 V to 16 V single supply or ±3 V to ±8 V dual supply configurations. At ±5 V, it delivers 68 Ω typical on-resistance and 35 ns enable turn-on time - verified per Vishay S21-0587-Rev. C specifications. Exceeding +18 V risks permanent damage.
Does DGQ4051EEQ-T1-GE4 support rail-to-rail analog signal switching?
Yes, DGQ4051EEQ-T1-GE4 supports true rail-to-rail analog signal switching: input signals may extend from V− to V+ without distortion or clipping. This is enabled by its CMOS transmission-gate design and internal level-shifting circuitry. The device maintains <0.3 pC charge injection and 2.2 pF source-off capacitance across the full range - critical for precision applications like battery cell monitoring where signals span near ground to full pack voltage.
Is DGQ4051EEQ-T1-GE4 qualified for automotive use?
Yes, DGQ4051EEQ-T1-GE4 is AEC-Q100 qualified (Grade 1), certified for operation from -40 °C to +125 °C ambient temperature. It undergoes stress testing including HTOL, thermal cycling, and ESD (2000 V HBM, 750 V CDM). This qualification is explicitly documented in Vishay's S21-0587-Rev. C datasheet and confirms suitability for under-hood automotive systems such as battery management and infotainment power domains.
What is the logic voltage threshold for the address pins (A, B, C) of DGQ4051EEQ-T1-GE4?
The DGQ4051EEQ-T1-GE4 address pins (A, B, C) and ENABLE pin require logic-high input ≥2 V when operating from 5 V or ±5 V supplies, and ≥1.4 V when operating from a 3 V supply - per Vishay S21-0587-Rev. C, Table "Digital Control". Input current remains ≤1 μA across temperature, ensuring compatibility with standard GPIOs of automotive MCUs and industrial microcontrollers without external level-shifting.
Can DGQ4051EEQ-T1-GE4 be used in both multiplexer and demultiplexer configurations?
Yes, DGQ4051EEQ-T1-GE4 functions bidirectionally: any analog terminal (X0–X7 or X) may serve as input or output. Its symmetrical on-resistance (68 Ω typ.), matched capacitance, and rail-to-rail capability allow direct use as a demultiplexer - e.g., routing one DAC output to eight sensor excitation lines. No external components or layout changes are needed; simply reverse signal flow direction per application requirements.
