Product details
Overview
DG4051EEY-T1-GE3 from Vishay Siliconix is an 8-channel analog multiplexer IC designed for high-precision signal routing in data acquisition and test equipment. It supports ±5 V dual-supply operation, delivers 68 Ω typical on-resistance at room temperature, achieves 35 ns enable turn-on time, and features 0.3 pC max charge injection-enabling low-distortion switching of rail-to-rail analog signals in medical instrumentation and automated test systems.
For engineers reviewing the DG4051EEY-T1-GE3 datasheet, DG4051EEY-T1-GE3 pinout, DG4051EEY-T1-GE3 application, or DG4051EEY-T1-GE3 equivalent, key selection criteria include its -40 °C to +125 °C operating range, 2.2 pF source-off capacitance, <50 pA leakage current, and compatibility with 3 V logic control inputs across single (3–16 V) and dual (±3 to ±8 V) supply configurations.
Technical Context
The DG4051EEY-T1-GE3 implements a CMOS-based 1-of-8 decoder architecture with enable-controlled channel selection. All eight analog switches conduct bidirectionally with rail-to-rail signal handling, and feature break-before-make timing to prevent signal shorting during state transitions.
Its internal level-shifting circuitry ensures guaranteed 2 V logic-high recognition at 5 V/±5 V supplies and 1.4 V at 3 V supply, while low parasitic capacitance (CD(on): 14.9 pF typ., CS(off): 2.2 pF typ.) and minimal charge injection preserve signal integrity in high-resolution sampling paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±5 V (dual supply); enables full-range AC coupling without clipping in instrumentation front-ends |
| On-Resistance (RON) | 68 Ω typ. at 25 °C; ensures minimal gain error and thermal drift in precision gain-setting networks |
| Charge Injection | 0.3 pC max over full voltage range; reduces settling error and droop in sample-and-hold circuits |
| Enable Turn-On Time | 35 ns typ.; supports high-throughput multiplexed ADC sampling at >10 MSPS effective rates |
| Leakage Current | <50 pA max at full temperature range; critical for maintaining accuracy in high-impedance sensor interfaces |
| Off-Isolation (OIRR) | -106 dB at 100 kHz; suppresses crosstalk between adjacent channels in multi-signal monitoring systems |
| Supply Voltage Range | 3 V to 16 V single or ±3 V to ±8 V dual; simplifies power architecture in mixed-voltage industrial controllers |

| 9 | V+ | Positive supply rail; must be ≥ |V−| + 0.3 V and ≤ +18 V relative to V− |
| 10 | V− | Negative supply rail; supports dual-supply operation down to −8 V |
| 11, 12, 13 | A, B, C | 3-bit binary address inputs; decode to select one of eight channels (X0–X7) |
| 14 | ENABLE | Active-low global enable; forces all switches open when high |
| 15 | X | Common analog output terminal; bidirectional signal path shared by all channels |
| 16 | GND | Logic ground reference; separate from analog ground but tied at system star point |

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-channel, ±15 V max supply, 100 Ω RON, 10 ns faster tON (25 ns), no 3 V logic compatibility | Higher voltage handling but less suitable for battery-powered or low-voltage MCU-controlled systems | Select when >±5 V signal ranges or sub-30 ns switching is required; verify level-shifter need for 3 V logic |
| ADG1408BRUZ | 8-channel, ±15 V supply, 4.5 Ω RON, 100x lower leakage (10 pA), 10× higher price, TSSOP-16 only | Better precision for metrology-grade instruments; not cost-optimized for volume industrial use | Choose for ultra-low-offset, low-drift applications where RON flatness and leakage dominate budget |

FAQ
What is the maximum supply voltage rating for DG4051EEY-T1-GE3?
The DG4051EEY-T1-GE3 has an absolute maximum V+ to V− rating of +18 V. When operated on dual supplies, it supports up to ±8 V; on single supplies, up to +16 V. Exceeding these limits risks permanent damage per the Absolute Maximum Ratings table in the Vishay datasheet S16-0623-Rev. A. Always maintain at least 0.3 V margin between supply rails and device terminals.
Does DG4051EEY-T1-GE3 support 3 V logic-level control inputs?
Yes, DG4051EEY-T1-GE3 supports 3 V logic control: its input high threshold is guaranteed at 1.4 V when operating from a 3 V supply, and at 2 V for 5 V or ±5 V supplies. This allows direct interfacing with 3 V microcontrollers and FPGAs without external level shifters, as confirmed in the Digital Control section of the datasheet.
What is the typical on-resistance flatness of DG4051EEY-T1-GE3 and why does it matter?
The DG4051EEY-T1-GE3 exhibits 10 Ω typical on-resistance flatness (RFLATNESS) over the full analog signal range at room temperature. This parameter quantifies variation in RON versus input voltage-critical in precision gain-setting and current-source applications where nonlinearity introduces harmonic distortion or gain error. At full temperature range, flatness degrades to 20 Ω max.
Can DG4051EEY-T1-GE3 be used in bidirectional signal paths?
Yes, DG4051EEY-T1-GE3 supports fully bidirectional analog signal flow: all channels conduct equally well from X0–X7 to X and vice versa, with rail-to-rail capability across the full supply range. This enables flexible use as both multiplexer and demultiplexer in reconfigurable signal chains, such as in programmable I/O modules or loopback test circuits.
What package type is DG4051EEY-T1-GE3 supplied in, and what are its key mechanical dimensions?
DG4051EEY-T1-GE3 is packaged in a 16-pin narrow SOIC (JEDEC MS-012) measuring 10.0 mm × 4.0 mm × 1.5 mm. Its lead pitch is 1.27 mm, body width is 3.9 mm, and it complies with RoHS and lead-free requirements. This package offers proven manufacturability, thermal performance (125 °C/W θJA), and compatibility with standard PCB assembly processes.
