Product details
Overview
DG3536DB-T5-E1 from Vishay Siliconix is a dual SPDT analog switch optimized for low-voltage signal routing in portable electronics, featuring 0.25 Ω on-resistance at 2.7 V, -69 dB off-isolation at 100 kHz, and MICRO FOOT® 10-bump (4 × 3 mm) package with 0.5 mm pitch. It supports 1.6 V logic-compatible control and delivers matched on-resistance (<0.05 Ω) and flatness (<0.2 Ω) across the full analog range.
For engineers reviewing the DG3536DB-T5-E1 datasheet, DG3536DB-T5-E1 pinout, DG3536DB-T5-E1 application, or DG3536DB-T5-E1 equivalent, key selection criteria include sub-1 Ω RON performance at ≤3.3 V supply, guaranteed break-before-make timing, ESD robustness (>2 kV), and compatibility with space-constrained audio routing and battery-powered system designs.
Technical Context
The DG3536DB-T5-E1 implements two independent SPDT analog switches using high-density low-voltage CMOS process with built-in epitaxial latchup protection. Each channel provides bidirectional conduction in the ON state and guarantees break-before-make switching with <6 ns typical transition interval.
It operates from 1.8 V to 3.3 V supply, accepts 0.5 V/1.4 V logic thresholds, and maintains -69 dB off-isolation and crosstalk up to 100 kHz while delivering 406 pF channel-on capacitance and 145 pF off-capacitance per terminal - critical for preserving signal integrity in audio and video paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 0.25 Ω at 2.7 V - enables minimal voltage drop and signal attenuation in low-level analog paths |
| Off-isolation (OIRR) | -69 dB at 100 kHz - suppresses coupling between inactive channels in multi-source routing |
| Break-before-make time | 1–6 ns - prevents momentary shorting during channel switching in sensitive signal chains |
| Logic threshold (VINH/VINL) | 1.4 V / 0.5 V - ensures reliable interface with 1.8 V and 2.5 V DSP/MCU GPIOs |
| ESD rating | >2000 V HBM - protects against handling damage in assembly and end-user environments |
| Supply current | 1 µA max - supports ultra-low-power operation in always-on audio subsystems |
| Charge injection | 21 pC - limits glitch-induced DC offset in precision sensor or audio front-end switching |
Pinout & Package
MICRO FOOT® 10-bump (4 × 3 mm, 0.5 mm pitch) package with SnAgCu lead-free terminations. Bump height: 238 µm. Land pattern requires non-solder-mask-defined copper pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2 | Digital control inputs | Active-high logic inputs controlling respective SPDT switch states (0 = NC closed, 1 = NO closed) |
| COM1, COM2 | Analog common terminals | Center nodes for bidirectional signal routing between NC and NO paths |
| NO1, NO2 | Normally open analog terminals | Connected to COM when corresponding IN = 1; isolated otherwise |
| NC1, NC2 | Normally closed analog terminals | Connected to COM when corresponding IN = 0; isolated otherwise |
| V+ | Positive supply rail | Accepts 1.8–3.3 V; powers internal CMOS switch array and level-shifting circuitry |
| GND | Ground reference | Return path for analog signals and digital control; must be low-impedance for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Sub-1 Ω on-resistance | 0.25 Ω at 2.7 V ensures <1 mV drop at 4 mA audio line current, preserving SNR in headset interfaces |
| Guaranteed break-before-make | Prevents signal shorting during transitions - essential for avoiding pop/click artifacts in audio paths |
| On-resistance matching | <0.05 Ω mismatch between channels enables precise differential signal routing without gain skew |
| Low logic thresholds | 0.5 V/1.4 V thresholds allow direct interfacing with 1.8 V microcontrollers without level shifters |
| MICRO FOOT® footprint | 4 × 3 mm area reduces PCB real estate by >60% vs. comparable SOIC-14 packages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSM1024DCQ | 0.35 Ω RON at 3 V; 10-pin DFN; no guaranteed break-before-make | Higher RON increases insertion loss in low-amplitude audio paths; lacks timing guarantee for glitch-sensitive systems | Select only if board layout accommodates larger 3 × 3 mm DFN and timing-critical audio artifacts are acceptable |
| MAX4684EUB+ | 0.5 Ω RON at 3 V; 10-pin µMAX; 1.8 V logic compatible but higher 10 nA leakage | Higher leakage degrades DC accuracy in sensor front-ends; larger package consumes more PCB area | Prefer for legacy µMAX footprints where MICRO FOOT® rework is impractical |
Compared with TSM1024DCQ and MAX4684EUB+, the DG3536DB-T5-E1 delivers superior on-resistance matching and guaranteed break-before-make timing - critical for minimizing audible artifacts in portable audio, while its MICRO FOOT® footprint enables denser layouts in space-constrained handheld designs.

FAQ
What is the maximum supply voltage rating for DG3536DB-T5-E1?
The DG3536DB-T5-E1 has an absolute maximum V+ rating of +6 V, but its specified operational range is 1.8 V to 3.3 V. Operating above 3.3 V may degrade RON flatness and increase leakage beyond datasheet limits. For reliable performance in portable systems, DG3536DB-T5-E1 should be used with regulated 2.7 V or 3.0 V supplies aligned with its 0.25 Ω RON specification point.
Does DG3536DB-T5-E1 support bidirectional analog signal flow?
Yes, DG3536DB-T5-E1 supports fully bidirectional analog conduction in the ON state - both COM-to-NO and COM-to-NC paths conduct equally regardless of signal polarity or direction. This capability is confirmed in the datasheet description stating "all switching elements conduct equally in both directions" and is essential for AC-coupled audio and sensor signal routing where signal direction varies dynamically.
Is DG3536DB-T5-E1 pin-compatible with DG3535DB-T5-E1?
Yes, DG3536DB-T5-E1 and DG3535DB-T5-E1 share identical MICRO FOOT® 10-bump pinout, package dimensions, and electrical specifications - differing only in internal logic polarity (DG3535 uses active-low enable, DG3536 uses active-high). The DG3536DB-T5-E1 truth table confirms logic "1" turns NO paths ON, making it functionally interchangeable with DG3535DB-T5-E1 only when control logic levels are inverted in firmware or external gating.
What is the thermal derating behavior of DG3536DB-T5-E1 above 70 °C?
DG3536DB-T5-E1 requires thermal derating above 70 °C at 5.7 mW/°C, as specified in the Absolute Maximum Ratings table. Its maximum power dissipation drops from 457 mW at 70 °C to approximately 400 mW at 85 °C ambient. This derating ensures junction temperature remains within safe limits during sustained operation in handheld devices where enclosure temperatures may exceed 70 °C.
How does the ESD protection of DG3536DB-T5-E1 compare to standard HBM requirements?
DG3536DB-T5-E1 exceeds JEDEC JS-001 Class 2 (2 kV) HBM ESD rating with >2000 V performance, verified per Method 3015.7. This level of protection is sufficient for most board-level handling and end-user environments, eliminating need for external TVS diodes in typical audio switch applications - a design advantage confirmed in the datasheet's "ESD protection > 2000 V" feature listing and supported by Vishay's qualification testing.
