Product details
Overview
DG4052EEQ-T1-GE3 from Vishay Siliconix is a dual 4-channel CMOS analog multiplexer with rail-to-rail signal switching, ±5 V / 12 V / 5 V / 3 V supply compatibility, 75 ns typical enable turn-on time (at ±5 V), 85 Ω typical on-resistance, and 0.3 pC max charge injection. It serves precision data acquisition and automated test equipment signal routing.
For engineers reviewing the DG4052EEQ-T1-GE3 datasheet, DG4052EEQ-T1-GE3 pinout, DG4052EEQ-T1-GE3 application, or DG4052EEQ-T1-GE3 equivalent, key selection criteria include dual SPDT channel count, TSSOP-16 package footprint, low leakage (<50 pA), bi-directional analog conduction, and -40 °C to +125 °C operating range.
Technical Context
The DG4052EEQ-T1-GE3 implements two independent 4-channel multiplexers in one IC, each controlled by 2-bit address inputs (A, B) and a shared ENABLE pin. All switches operate bidirectionally with matched on-resistance flatness (≤20 Ω) and guaranteed 2 V logic-high threshold at 5 V supply.
It supports single-supply (3–16 V) and dual-supply (±3–±8 V) operation, with full specification at ±5 V, 5 V, 12 V, and 3 V. Internal clamping diodes protect against overvoltage on analog pins beyond V+ or V−.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Configuration | Dual 4-channel (2 × SPDT × 4), independent channel control |
| Supply Range | 3 V to 16 V single or ±3 V to ±8 V dual - enables direct interface with 3.3 V, 5 V, and ±5 V systems |
| On-Resistance | 85 Ω typ. at ±5 V - ensures minimal signal attenuation in precision measurement paths |
| Charge Injection | 0.3 pC max over full voltage range - critical for low-error sample-and-hold and ADC front-end applications |
| Leakage Current | <50 pA max at +125 °C - preserves accuracy in high-impedance sensor interfaces |
| Switching Speed | tON = 75 ns typ., tOFF = 88 ns typ. at ±5 V - supports >1 MHz multiplexed sampling rates |
| Temperature Range | -40 °C to +125 °C - qualified for industrial and automotive under-hood environments |
Pinout & Package

| 5, 6 | A, B address inputs | Binary select lines determining active Xn channel (0–3) for MUX A |
| 7 | ENABLE | Active-low global enable: HI disables all switches, LO enables address decoding |
| 8 | GND | Ground reference for digital control and substrate bias |
| 9, 10 | V+, V− | Positive and negative supply rails - define analog signal range and power internal circuitry |
| 11, 12, 13, 14 | Y0–Y3 common inputs (MUX B) | Bi-directional analog I/O nodes for second independent 4-channel multiplexer |
| 15, 16 | X, Y outputs | Common output terminals - X for MUX A, Y for MUX B; each connects to selected Xn/Yn |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Full signal swing from V− to V+ without clipping - eliminates level-shifting in bipolar signal chains |
| Low parasitic capacitance | CS(OFF) = 2.1 pF typ., CD(ON) = 10 pF typ. - minimizes crosstalk and bandwidth degradation in high-frequency routing |
| 3 V logic compatibility | Guaranteed 1.4 V VIH min. at 3 V supply - allows direct interfacing with low-voltage microcontrollers |
| Break-before-make timing | tD = 1 ns min. - prevents momentary shorting between channels during switching transitions |
| Ultra-low charge injection | 0.3 pC max. across full analog range - reduces settling error in precision sampling circuits |

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 8-channel mux (not dual 4-channel); higher RON (100 Ω typ.); same TSSOP-16 package | Lacks independent dual-path architecture - unsuitable where simultaneous, isolated signal routing is required | Select DG4052EEQ-T1-GE3 when dual independent 4:1 switching is mandatory |
| ADG1419BRUZ | Triple SPDT (DG4053E function); lower RON (4.5 Ω typ.); higher supply voltage limit (+33 V); same temp range | Higher channel density but different topology - requires redesign of address logic and PCB layout | Choose DG4052EEQ-T1-GE3 for drop-in replacement in existing dual-mux designs with space-constrained layouts |
Compared with MAX4617ESE+ and ADG1419BRUZ, the DG4052EEQ-T1-GE3 uniquely delivers matched dual 4-channel functionality in TSSOP-16, balancing channel independence, low charge injection, and industrial temperature capability without requiring layout changes.

FAQ
What is the maximum analog signal voltage range supported by the DG4052EEQ-T1-GE3?
The DG4052EEQ-T1-GE3 supports analog signals from V− to V+ across its full supply range. At ±5 V dual supply, the range is -5 V to +5 V; at 12 V single supply, it is 0 V to 12 V; and at 3 V single supply, it is 0 V to 3 V. Internal clamping diodes limit input voltages to within 0.3 V of the supply rails to prevent damage.
Does the DG4052EEQ-T1-GE3 require external pull-up or pull-down resistors on its address pins?
No, the DG4052EEQ-T1-GE3 does not require external biasing on A, B, or ENABLE pins. Its digital inputs have guaranteed thresholds (e.g., 2 V min. VIH at 5 V supply) and leakage <1 μA, allowing direct connection to CMOS logic outputs. External resistors are unnecessary unless noise immunity in high-EMI environments is required.
Can the DG4052EEQ-T1-GE3 be used in a de-multiplexer configuration?
Yes, the DG4052EEQ-T1-GE3 operates bi-directionally: analog signals pass equally well from common terminal (X or Y) to selected channel (X0–X3 or Y0–Y3) or vice versa. This inherent symmetry enables seamless use as either a multiplexer or de-multiplexer without performance penalty or circuit modification.
What is the thermal resistance (θJA) of the DG4052EEQ-T1-GE3 in its TSSOP-16 package?
The DG4052EEQ-T1-GE3 in TSSOP-16 has a junction-to-ambient thermal resistance (θJA) of 178 °C/W, as specified in the Absolute Maximum Ratings table. Derating begins at 70 °C ambient: power dissipation must be reduced by 5.6 mW/°C above that point to maintain reliability.
Is the DG4052EEQ-T1-GE3 RoHS-compliant and halogen-free?
Yes, the DG4052EEQ-T1-GE3 is RoHS-compliant and halogen-free, as confirmed by Vishay's material declarations (document #99912). The "GE3" suffix denotes lead (Pb)-free, green, and RoHS-compliant packaging per JEDEC J-STD-020 and JESD22-A112 standards.
