Product details
Overview
DG9454EEN-T1-GE4 from Vishay Siliconix is a triple SPDT (2:1) analog switch/multiplexer optimized for precision signal routing in low-power, wide-supply systems. It operates from 3 V to 16 V on V+, supports 1.8 V logic control across full voltage range, delivers rail-to-rail analog switching, and features 8.8 pF channel-on capacitance and 356 MHz bandwidth - enabling high-fidelity signal path selection in portable medical sensors and battery-powered instrumentation.
For engineers reviewing the DG9454EEN-T1-GE4 datasheet, DG9454EEN-T1-GE4 pinout, DG9454EEN-T1-GE4 application, or DG9454EEN-T1-GE4 equivalent, this page provides verified functional identity, validated miniQFN16 pin mapping, confirmed -40 °C to +125 °C operation, exact leakage and on-resistance specs at 3/5/12 V, and two rigorously cross-checked alternative parts with documented technical differences.
Technical Context
The DG9454EEN-T1-GE4 integrates three independent SPDT switches with bi-directional rail-to-rail analog conduction, driven by a decoded 3-bit select bus (A, B, C) and global enable. Its advanced CMOS process ensures matched on-resistance (≤8 Ω max ΔRON) and ultra-low charge injection (0.58–5.84 pC), critical for precision data acquisition where signal integrity must be preserved across varying supply voltages.
It employs dual-supply architecture: V+ (3–16 V) powers analog paths and internal level shifters, while VL (2.5–5.5 V) supplies logic interface - guaranteeing 1.8 V logic compatibility regardless of V+ level. The device meets JEDEC reflow standards in its Pb-free nickel-palladium-gold terminated miniQFN16 package (1.8 mm × 2.6 mm × 0.55 mm).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V+ Supply Range | 3 V to 16 V - enables direct integration into mixed-voltage systems without external regulators |
| Logic Compatibility | Guaranteed 1.8 V logic inputs over full V+ range - eliminates level-shifter requirement in low-VL designs |
| On-Resistance (RON) | 85 Ω typ @ 12 V, 125 Ω typ @ 5 V, 221 Ω typ @ 3 V - maintains predictable signal attenuation across operating voltages |
| Channel-On Capacitance | 8.8 pF @ 12 V - minimizes high-frequency loading and preserves bandwidth in RF-sensitive paths |
| Bandwidth (-3 dB) | 356 MHz @ RL = 50 Ω - supports fast-switching applications including video routing and high-speed DAQ |
| Charge Injection | 0.58 pC @ 3 V, 1.44 pC @ 5 V, 5.84 pC @ 12 V - ensures minimal glitch energy in sample-and-hold circuits |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive and industrial control environments |
Pinout & Package
The DG9454EEN-T1-GE4 is housed in a 16-pin ultra-compact miniQFN package (1.8 mm × 2.6 mm × 0.55 mm) with exposed thermal pad and Pb-free NiPdAu terminations compliant with JEDEC MSL3 reflow standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | X0, Y0, Z0 (Common Outputs) | Three independent SPDT common terminals - each routes analog signals to either X1/Y1/Z1 or X0/Y0/Z0 based on A/B/C select |
| 5, 6, 7, 8 | X1, Y1, Z1 (Throw 1 Outputs) | First throw path per switch - connected when corresponding A/B/C bit = HIGH |
| 9, 10, 11, 12 | A, B, C (Select Inputs) | 3-bit binary address bus controlling all three SPDT switches simultaneously |
| 13 | ENABLE | Global active-low enable - disables all switches when HIGH, reducing leakage and power consumption |
| 14 | GND | Analog/digital ground reference - must be low-impedance connection for signal integrity |
| 15 | VL | Logic supply input (2.5–5.5 V) - powers internal level shifters and digital interface |
| 16 | V+ | Analog supply input (3–16 V) - defines analog signal swing and on-resistance performance |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Full signal range from GND to V+ supported in both directions - eliminates clipping in ±12 V or single-supply sensor interfaces |
| Low parasitic capacitance | CD(ON) = 8.8 pF, CS(OFF) = 3.1 pF - reduces crosstalk and preserves high-frequency response in multi-channel systems |
| Ultra-low leakage current | ±0.02 nA max IS(off) @ 3 V, ±0.05 nA @ 12 V - critical for high-impedance medical electrode front-ends |
| Break-before-make timing | tD = 1 ns min @ 25 °C - prevents momentary shorting during state transitions in multiplexed sensor arrays |
| Compact miniQFN16 footprint | 1.8 mm × 2.6 mm area - saves >60% board space vs. comparable SOIC-16 switches in portable goggle and wearable designs |

FAQ
What is the maximum analog signal voltage range supported by the DG9454EEN-T1-GE4?
The DG9454EEN-T1-GE4 supports analog signals from GND to V+ across its full operating range: 0–3 V at V+ = 3 V, 0–5 V at V+ = 5 V, and 0–12 V at V+ = 12 V. Absolute maximum analog voltage is clamped to V+ + 0.3 V by internal diodes, and operation beyond V+ risks permanent damage. This rail-to-rail capability is confirmed in the "Analog Signal Range" specification table for unipolar supplies.
Does the DG9454EEN-T1-GE4 require separate analog and logic ground connections?
No, the DG9454EEN-T1-GE4 uses a single GND pin (Pin 14) for both analog and digital return paths. Its internal architecture shares ground reference across V+, VL, and signal terminals. However, layout best practice requires a low-impedance, star-connected ground plane beneath the miniQFN thermal pad to minimize noise coupling - as specified in Vishay's recommended pad pattern document 66557.
Can the DG9454EEN-T1-GE4 operate with VL = 1.8 V while V+ = 12 V?
No - the datasheet specifies VL must be between 2.5 V and 5.5 V. At V+ = 12 V, VL = 1.8 V falls outside this range and violates absolute maximum ratings. Logic supply below 2.5 V may cause undefined decode behavior or increased input current. The 1.8 V logic compatibility refers to input voltage thresholds (VINH/VINL), not VL supply voltage.
What is the thermal resistance (θJA) of the DG9454EEN-T1-GE4 in its miniQFN16 package?
The DG9454EEN-T1-GE4 has a junction-to-ambient thermal resistance (θJA) of 152 °C/W when mounted on a standard JEDEC 2-layer board with 1 in² copper area. This value assumes proper soldering to the exposed thermal pad per Vishay's mounting guidelines. Derating begins above 70 °C at 6.6 mW/°C, limiting max power dissipation to 525 mW at TA = 70 °C.
Is the DG9454EEN-T1-GE4 pin-compatible with earlier DG9454 variants like DG9454YU-E3?
Yes - the DG9454EEN-T1-GE4 shares identical pinout, electrical specifications, and miniQFN16 footprint with DG9454YU-E3 and DG9454EEN. All variants use the same functional block diagram and truth table. The "-GE4" suffix denotes Pb-free NiPdAu termination and MSL3 compliance, but does not affect pin assignment or signal behavior.
