Product details
Overview
DG2733DQ-T1-E3 from Vishay Siliconix is a low-voltage, dual SPDT analog switch with 0.4 Ω typical on-resistance at 4.3 V, 1.6 V to 4.3 V single-supply operation, and integrated enable (EN) control logic. It routes bidirectional audio/video signals in portable battery-powered systems, supports break-before-make switching, and delivers 50 ns turn-on time at 4.3 V.
For engineers reviewing the DG2733DQ-T1-E3 datasheet, DG2733DQ-T1-E3 pinout, DG2733DQ-T1-E3 application, or DG2733DQ-T1-E3 equivalent, key selection criteria include its 0.4 Ω rON at 4.3 V, EN-controlled activation, MSOP-10 lead-free packaging, and guaranteed break-before-make timing for signal integrity in headset and PCMCIA switching.
Technical Context
The DG2733DQ-T1-E3 implements dual independent SPDT switches using sub-micron CMOS process technology, with EN pin enabling both channels simultaneously under high-logic assertion. Its control architecture eliminates simultaneous conduction via guaranteed 5 ns minimum break-before-make interval at 4.3 V.
It operates across 1.6 V to 4.3 V supply range while maintaining TTL/1.6-V logic compatibility, supporting direct interface with Li-ion battery–powered MCUs and DSPs. Analog signal handling spans full rail-to-rail (0 V to V+) with ±250 mA continuous channel current and >300 mA latch-up immunity per JESD78.

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 |
|---|---|---|---|
| TMUX1574RSVR | 0.5 Ω rON @ 3.3 V; no EN pin; 1.8–5.5 V supply | Requires external logic for enable function; higher rON increases insertion loss | Choose when wider supply range outweighs need for integrated EN control |
| ADG732BRUZ | 0.8 Ω rON @ 3 V; 16-channel; SPI interface; 1.8–5.5 V | Over-specified channel count and serial interface add complexity for simple dual-SPDT use | Choose only if system requires programmable multi-channel routing beyond two SPDTs |
Compared with TMUX1574RSVR and ADG732BRUZ, the DG2733DQ-T1-E3 provides lower on-resistance (0.4 Ω), integrated EN functionality, and optimized performance for compact, battery-powered dual-path switching - making it preferable where minimal BOM count, low power, and fast analog routing are critical.

FAQ
What is the maximum supply voltage rating for DG2733DQ-T1-E3?
The DG2733DQ-T1-E3 has an absolute maximum supply voltage (V+) of 5.0 V, but its specified operational range is 1.6 V to 4.3 V. Operating above 4.3 V may degrade performance or reliability, and the device is not characterized beyond that voltage. Always refer to the Absolute Maximum Ratings table in the official Vishay datasheet (Document Number 73484) for safe design margins.
Does DG2733DQ-T1-E3 support rail-to-rail analog signal switching?
Yes, the DG2733DQ-T1-E3 supports full rail-to-rail analog signal switching - signals on COM, NO, and NC terminals can swing from 0 V to V+ without degradation. This capability is confirmed across all operating voltages (1.6 V to 4.3 V) and enables accurate handling of audio, sensor, and video signals in portable systems powered directly by Li-ion batteries.
How does the EN pin on DG2733DQ-T1-E3 differ from the control pins on DG2731/DG2732?
The DG2733DQ-T1-E3 uses a single active-high EN pin to enable both SPDT channels simultaneously, whereas DG2731 and DG2732 use separate IN1 and IN2 pins with reverse logic. This simplifies system-level control by reducing required GPIOs and eliminating timing skew between channels - a key advantage in synchronized audio path switching applications requiring coordinated dual-channel activation.
What is the guaranteed break-before-make time for DG2733DQ-T1-E3?
The DG2733DQ-T1-E3 guarantees a minimum break-before-make time of 5 ns at V+ = 4.3 V, as specified in the datasheet's "SPECIFICATIONS (V+ = 4.3 V)" table. This parameter ensures no overlap between NC and NO conduction states during switching, preventing momentary shorts in sensitive analog circuits such as headphone amplifiers or sensor front-ends.
Is DG2733DQ-T1-E3 compatible with 1.8 V logic systems?
Yes, DG2733DQ-T1-E3 is fully compatible with 1.8 V logic systems: its input high voltage (VINH) threshold is 1.4 V min at V+ = 1.8 V, and its input low voltage (VINL) is 0.4 V max - well within standard 1.8 V CMOS logic levels. This allows direct interfacing with 1.8 V FPGAs, microcontrollers, and audio codecs without level-shifting circuitry.
