Product details
Overview
DG2753DQ-T1-E3 from Vishay Siliconix is a triple SPDT analog switch IC designed for low-voltage signal routing in portable electronics. It operates from 1.65 V to 4.3 V, delivers 0.9 Ω on-resistance at 2.7 V, 30 ns turn-on time, and supports 1.8 V logic compatibility - enabling direct interface with Li-ion–powered MCUs in audio headset switching applications.
For engineers reviewing the DG2753DQ-T1-E3 datasheet, DG2753DQ-T1-E3 pinout, DG2753DQ-T1-E3 application, or DG2753DQ-T1-E3 equivalent, key selection criteria include guaranteed break-before-make timing, ±300 mA latch-up immunity per JESD78, and QFN-16 (3 × 3 mm) package suitability for space-constrained PCB layouts in battery-operated systems.
Technical Context
The DG2753DQ-T1-E3 integrates three independent SPDT switches fabricated on Vishay's low-voltage CMOS process with epitaxial isolation to prevent latch-up. Each channel exhibits 0.1 Ω RON matching and 0.2 Ω max RON flatness at 2.7 V, ensuring consistent analog signal integrity across all paths.
Its digital control inputs are fully compatible with 1.8 V TTL logic across the full 1.65–4.3 V supply range, and the device guarantees functional operation down to V+ = 1.8 V. Break-before-make timing is specified at 5–30 ns, eliminating signal shorting during state transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 4.3 V - enables single-cell Li-ion (2.7–4.2 V) and dual-cell alkaline (3 V) direct power without regulation |
| On-Resistance (rDS(on)) | 0.9 Ω typ at 2.7 V - minimizes voltage drop and distortion in audio/video signal paths |
| Turn-On/Off Time | 30 ns / 10 ns - supports high-speed multiplexing in USB audio or fast-switching sensor interfaces |
| RON Matching | 0.1 Ω max - ensures matched gain/attenuation across channels in stereo or differential routing |
| Latch-Up Immunity | >300 mA per JESD78 - eliminates risk of destructive latch-up under transient overvoltage conditions |
| Logic Compatibility | 1.8 V TTL - allows direct connection to low-voltage DSPs, FPGAs, and ARM Cortex-M I/O without level shifters |
Pinout & Package
Package: QFN-16 (3 mm × 3 mm), exposed thermal pad, lead (Pb)-free with matte tin terminations (-E3 suffix). RoHS-compliant, MSL 1, reflow-compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16 | Switch terminals (X0/X1/Y0/Y1/Z0/Z1, COM/NO/NC), Enable, GND, V+ | 16-pin configuration supports three independent SPDT switches plus global enable and power pins - no NC pins in QFN variant |

Key Features
| Feature | Design Value |
|---|---|
| Triple SPDT architecture | Enables simultaneous stereo audio path selection (left/right + mic) or multi-source video routing in one package |
| Break-before-make guarantee | Prevents momentary short-circuit between signal sources during switching - critical for analog mux safety |
| 0.2 Ω RON flatness | Maintains linear signal transfer across full analog input range (0–V+), reducing harmonic distortion |
| 35 pF off-capacitance | Minimizes crosstalk and capacitive loading on adjacent traces in high-density portable PCBs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4673ETE+ | Higher rON (1.5 Ω @ 3 V), TSSOP-16 only, no QFN option | Less suitable for ultra-thin mobile designs requiring 3 × 3 mm footprint | Select when legacy TSSOP layout reuse is prioritized over size reduction |
| TS5A3159DRCR | Single SPDT ×3 array, 0.75 Ω rON, but no guaranteed break-before-make | Requires external timing control for safe switching in shared-signal systems | Select when lowest on-resistance is critical and system-level timing can be managed externally |
Compared with MAX4673ETE+ and TS5A3159DRCR, the DG2753DQ-T1-E3 uniquely combines QFN-16 miniaturization, guaranteed break-before-make, and 1.8 V logic compatibility - making it optimal for next-generation compact, battery-powered audio routing where reliability and layout efficiency are co-prioritized.

FAQ
What is the maximum supply voltage rating for DG2753DQ-T1-E3?
The DG2753DQ-T1-E3 has an absolute maximum supply voltage (V+) of 5.0 V, but its specified operational range is 1.65 V to 4.3 V. Operating above 4.3 V may cause parametric degradation or reliability risk, even if below the 5.0 V absolute limit. The DG2753DQ-T1-E3 is optimized for Li-ion battery rails (2.7–4.2 V) and must not be used continuously at 4.5 V or higher without validation.
Does DG2753DQ-T1-E3 support break-before-make switching across all three SPDT channels?
Yes, the DG2753DQ-T1-E3 guarantees break-before-make timing of 5–30 ns across all three SPDT channels, as verified per test circuit Figure 2 in the official datasheet. This prevents momentary shorting between signal sources during switching transitions - a critical requirement for protecting sensitive analog inputs in audio and sensor applications using the DG2753DQ-T1-E3.
Is DG2753DQ-T1-E3 pin-compatible with the TSSOP-16 version DG2753DQ-T1-E3?
No - DG2753DQ-T1-E3 uses the QFN-16 (3 × 3 mm) package, while the TSSOP-16 variant is DG2753DQ-T1-E3 (same part number suffix but different package code). They share identical pin functions and electrical specs, but physical pinouts differ due to QFN's perimeter-only pad layout versus TSSOP's gull-wing leads. PCB redesign is required when substituting DG2753DQ-T1-E3 for TSSOP versions.
What is the off-isolation performance of DG2753DQ-T1-E3 at 1 MHz?
The DG2753DQ-T1-E3 provides −90 dB typical off-isolation (OIRR) at 500 kHz, as measured with V+ = 2.7 V, CL = 1 nF, and RGEN = 0 Ω. While not explicitly tested at 1 MHz in the datasheet, the characteristic curve in Figure 5 shows isolation remains above −85 dB up to 100 MHz - confirming robust signal blocking for audio-band and low-speed data routing in the DG2753DQ-T1-E3.
Can DG2753DQ-T1-E3 operate reliably at 1.65 V supply?
Yes - the DG2753DQ-T1-E3 is fully specified down to 1.65 V supply, with guaranteed functionality including 1.8 V logic compatibility, 0.9 Ω rDS(on), and 30 ns tON. At 1.65 V, on-resistance increases slightly (to ~1.5 Ω max), but all timing and leakage parameters remain within datasheet limits - making the DG2753DQ-T1-E3 suitable for deep-discharge battery operation in portable devices.
