Product details
Overview
DGQ4052EEQ-T1-GE4 from Vishay Siliconix is a dual 4-channel analog multiplexer (4:1 × 2) with rail-to-rail bi-directional switching, 3 V to 16 V single-supply or ±3 V to ±8 V dual-supply operation, <50 pA typical leakage, 0.3 pC max charge injection, and 35 ns typical enable turn-on time. It serves precision signal routing in automotive battery management and infotainment systems.
For engineers reviewing the DGQ4052EEQ-T1-GE4 datasheet, DGQ4052EEQ-T1-GE4 pinout, DGQ4052EEQ-T1-GE4 application, or DGQ4052EEQ-T1-GE4 equivalent, key selection criteria include on-resistance matching (≤6 Ω), low off-capacitance (CD(OFF) = 4.8 pF typ.), AEC-Q100 Grade 1 qualification, and TSSOP16 package compatibility with high-density PCB layouts.
Technical Context
The DGQ4052EEQ-T1-GE4 implements two independent 4:1 analog multiplexers sharing common control logic (A, B, ENABLE) and supply rails (V+, V−, GND). Each channel conducts equally in both directions with no polarity dependence, enabling use as multiplexers or demultiplexers.
It features CMOS transmission-gate architecture with level-shifted control inputs guaranteed functional at 1.4 V (3 V supply) or 2 V (5 V/±5 V supply), and includes internal diode clamping for analog signals exceeding V+ or V− - requiring external current limiting per datasheet note.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Config | Dual 4:1 multiplexer (4:1 × 2), independent channels with shared address/control |
| Supply Range | 3 V to 16 V single supply or ±3 V to ±8 V dual supply - supports legacy 5 V, modern 3.3 V, and high-voltage 12 V automotive rails |
| On-Resistance | 78 Ω max (±5 V), 103 Ω max (12 V), 147 Ω max (5 V unipolar) - ensures minimal signal attenuation in sensor and ADC front-end paths |
| Charge Injection | ≤0.38 pC (dual supply), ≤0.32 pC (12 V), ≤0.34 pC (3 V) - critical for low-error sample-and-hold and precision data acquisition |
| Off-Isolation | −68 dB @ 10 MHz (±5 V), −86 dB @ 100 kHz (12 V) - suppresses crosstalk between active and inactive channels in multi-signal systems |
| Switching Time | tON = 35 ns typ. (±5 V), tOFF = 48 ns typ. (±5 V), tTRANS = 72 ns typ. - enables high-speed multiplexing in real-time control loops |
| Leakage Current | ±50 pA max (full temp range) - preserves accuracy in high-impedance sensor interfaces and battery monitoring shunt measurements |

| 9, 10 | V+ | Positive supply rail; powers analog switches and internal logic; accepts up to +18 V |
| 11, 12 | X, Y outputs | Common outputs - X for Channel 1, Y for Channel 2; each connects to selected input |
| 13, 14 | A, B | Binary address inputs (LSB, MSB); control channel selection (00–11) for both muxes simultaneously |
| 15 | ENABLE | Active-low enable; pulls all switches open when high; logic threshold 0.6 V/2 V (3 V/5 V) |
| 16 | NC | No connect - internally unused; must be left floating or tied to GND per layout guidelines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Single 4:1 mux (not dual), higher RON (100 Ω typ.), no AEC-Q100 qualification | Suitable for commercial-grade instrumentation only; lacks automotive temperature range and dual-channel integration | Select if only one 4:1 path needed and AEC-Q100 not required |

FAQ
What is the maximum supply voltage rating for DGQ4052EEQ-T1-GE4?
The DGQ4052EEQ-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. Exceeding +18 V differential or applying >18 V across V+ and V− risks permanent damage, per Absolute Maximum Ratings table in Vishay S21-0587-Rev. C.
Does DGQ4052EEQ-T1-GE4 support rail-to-rail analog signal switching?
Yes, DGQ4052EEQ-T1-GE4 supports true rail-to-rail analog signal switching - signals from V− to V+ pass through with minimal distortion. This is enabled by its CMOS transmission-gate design and verified across all specified supply conditions (±5 V, 12 V, 5 V, 3 V), making it suitable for direct interfacing with op-amps and ADCs operating at supply rails.
What is the guaranteed logic high threshold for ENABLE and address pins at 3 V supply?
At 3 V supply, the DGQ4052EEQ-T1-GE4 guarantees a logic high input threshold (VIH) of 1.4 V for ENABLE, A, and B pins - ensuring reliable activation with standard 3 V microcontroller GPIOs without external level shifting. This is explicitly specified in the "Digital Control" section under "SPECIFICATIONS FOR UNIPOLAR SUPPLIES" (V+ = 3 V, V− = 0 V).
Is DGQ4052EEQ-T1-GE4 qualified for automotive applications?
Yes, DGQ4052EEQ-T1-GE4 is AEC-Q100 qualified (Grade 1), rated for operation from −40 °C to +125 °C, and designed for automotive battery management, infotainment, and telematics systems. Its qualification includes stress testing for thermal cycling, humidity, ESD (2000 V HBM), and latch-up immunity (100 mA), as documented in Vishay S21-0587-Rev. C.
How does charge injection performance vary with supply voltage in DGQ4052EEQ-T1-GE4?
DGQ4052EEQ-T1-GE4 maintains ≤0.38 pC charge injection across all tested conditions: 0.38 pC (±5 V), 0.32 pC (12 V), and 0.34 pC (3 V), per "Dynamic Characteristics" tables. This consistency ensures predictable settling behavior in sample-and-hold circuits regardless of system supply architecture - critical for precision data acquisition in mixed-voltage automotive ECUs.
