Product details
Overview
DG2032DN-T1-E4 from Vishay Siliconix is a monolithic CMOS dual SPDT analog switch optimized for low-voltage, high-bandwidth signal routing. It operates from 1.8 V to 5.5 V, delivers 2.4 Ω typical on-resistance at 2.7 V, achieves –81 dB crosstalk and off-isolation at 1 MHz, and is housed in a 12-pin QFN (3 × 3 mm) package. It is used in audio/video switching, cellular handset headset routing, and low-voltage data acquisition systems.
For engineers reviewing the DG2032DN-T1-E4 datasheet, DG2032DN-T1-E4 pinout, DG2032DN-T1-E4 application, or DG2032DN-T1-E4 equivalent, key selection criteria include guaranteed break-before-make timing, sub-30 ns turn-on time, low 38 pC charge injection, rON flatness ≤1.6 Ω, and full rail-to-rail analog signal handling up to V+.
Technical Context
The DG2032DN-T1-E4 integrates two independent SPDT switches with separate digital control inputs (IN1/IN2), each selecting between NO1/NO2 and NC1/NC2 paths while connecting to shared COM1/COM2 terminals. Its CMOS architecture ensures bidirectional conduction, rail-to-rail analog voltage support (0 to V+), and latch-up immunity via epitaxial layer construction.
Dynamic performance is defined by guaranteed break-before-make operation, 28 ns typical tON and 13 ns tOFF at 3 V with 50 Ω/35 pF load, and –82 dB crosstalk at 1 MHz. Off-isolation exceeds –78 dB under identical conditions, and channel capacitance remains stable at CNO(on) = 49 pF and CNO(off) = 15 pF.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4682EUB+ | Higher rON (3.5 Ω typ), wider supply (1.8–5.5 V), same QFN-10 package but different pinout | Lower bandwidth (–70 dB crosstalk @ 1 MHz); less suitable for audio-grade routing | Select when footprint compatibility with MAX46xx family is required and lower isolation is acceptable |
| ADG732BRUZ | 32-channel single-pole switch, not dual SPDT; 4 Ω rON, SPI interface, TSSOP-38 package | Requires serial control and larger board area; suited for high-channel-count, low-speed scanning | Choose only for multi-channel multiplexing where parallel control and compact dual-SPDT topology are not needed |
Compared with MAX4682EUB+ and ADG732BRUZ, the DG2032DN-T1-E4 offers superior high-frequency isolation (–82 dB), lower charge injection (38 pC), and native dual-SPDT topology in a space-optimized QFN-12 - making it optimal for portable audio, compact ATE, and low-voltage mixed-signal routing where timing integrity and signal fidelity are critical.

FAQ
What is the maximum analog signal voltage range supported by the DG2032DN-T1-E4?
The DG2032DN-T1-E4 supports analog signals from 0 V to V+, where V+ ranges from 1.8 V to 5.5 V. At V+ = 3.3 V, the full analog range is 0–3.3 V; at V+ = 5.0 V, it extends to 0–5.0 V. This rail-to-rail capability is guaranteed across the full operating temperature range (–40 °C to +85 °C) and ensures compatibility with both low-voltage logic and higher-voltage analog sources without external level shifting. The DG2032DN-T1-E4 maintains specified rON and leakage performance across this entire range.
Does the DG2032DN-T1-E4 require external pull-up or pull-down resistors on its digital control inputs?
No, the DG2032DN-T1-E4 does not require external pull-up or pull-down resistors on IN1 or IN2. Its digital inputs are CMOS-compatible with guaranteed logic thresholds: VINH ≥ 2.0 V and VINL ≤ 0.4 V over the full supply range (1.8–5.5 V). Input leakage is ≤1 µA, and input capacitance is only 5 pF, allowing direct connection to microcontroller GPIOs, FPGA outputs, or dedicated logic drivers without additional biasing. This simplifies design and reduces BOM count for the DG2032DN-T1-E4.
How is break-before-make timing ensured in the DG2032DN-T1-E4?
Break-before-make timing in the DG2032DN-T1-E4 is guaranteed by internal circuit design - not process variation - with a minimum delay (td) of 1 ns between turn-off of the previously selected path and turn-on of the new path. This is verified across voltage (1.8–5.5 V), temperature (–40 °C to +85 °C), and process corners. The DG2032DN-T1-E4 truth table confirms that logic '0' connects NC and logic '1' connects NO, with no overlap window. This eliminates signal shorting risks in sensitive audio or sensor paths.
Can the DG2032DN-T1-E4 be used in bidirectional signal paths?
Yes, the DG2032DN-T1-E4 supports fully bidirectional analog signal flow. Both COM1/COM2 terminals can serve as either input or output, and signal conduction is symmetric - rON, capacitance, and leakage specifications apply identically regardless of current direction. This makes the DG2032DN-T1-E4 suitable for applications like stereo headset detection (where COM senses plug insertion) and bidirectional sensor interfaces. No polarity constraints exist on NO/NC/COM nodes in the DG2032DN-T1-E4.
What thermal considerations apply to the DG2032DN-T1-E4 in continuous operation?
The DG2032DN-T1-E4 has a maximum power dissipation of 1295 mW in its QFN-12 package at +70 °C ambient, with thermal derating of 16.2 mW/°C above that temperature. For continuous 50 mA per channel operation at 3.3 V, power dissipation remains below 200 mW - well within safe limits. The exposed die pad must be soldered to a thermal pad on the PCB for effective heat transfer. The DG2032DN-T1-E4 is rated for storage from –65 °C to +150 °C and operates reliably from –40 °C to +85 °C.
