Product details
Overview
DG9424DQ-T1-E3 from Vishay Siliconix is a low-voltage, dual-supply, quad SPST analog switch with 1.7 Ω on-resistance, 42 ns turn-on time, and ±3 V to ±6 V or 3 V to 12 V supply operation. It features break-before-make switching, 2000 V ESD protection, and is optimized for audio/video signal routing in precision instrumentation.
For engineers reviewing the DG9424DQ-T1-E3 datasheet, DG9424DQ-T1-E3 pinout, DG9424DQ-T1-E3 application, or DG9424DQ-T1-E3 equivalent, key selection criteria include on-resistance flatness over signal range, crosstalk (-77 dB), off-isolation (-56 dB), and TSSOP-16 package compatibility with high-density PCB layouts.
Technical Context
The DG9424DQ-T1-E3 implements BiCMOS process technology to support both single- and dual-supply operation while maintaining low RON and fast switching. Its control logic is active-high (ON when IN = 1), distinct from the DG9425's inverted logic and DG9426's mixed NO/NC configuration.
Each of its four independent SPST switches exhibits flat RON across the full analog signal range (0–12 V single supply or ±5 V dual supply), minimal charge injection (38 pC), and guaranteed break-before-make timing (2 ns minimum) - critical for preventing signal shorting in multiplexed data acquisition paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 1.7 Ω typical at 12 V single supply - ensures <1% signal attenuation in 50 Ω systems and low thermal drift in precision sensor interfaces |
| Turn-on time (tON) | 42 ns typical - enables reliable switching at >10 MHz sample rates in ADC front-end multiplexing |
| Analog signal range | 0 to 12 V (single supply) or ±5 V (dual supply) - supports rail-to-rail audio, video, and industrial sensor signals without clipping |
| Off-isolation (OIRR) | -56 dB at 1 MHz - suppresses coupling between inactive channels in multi-channel ATE and communication systems |
| Crosstalk (XTALK) | -77 dB at 1 MHz - preserves signal integrity in adjacent switched paths, e.g., stereo audio routing |
| ESD protection | 2000 V HBM - eliminates need for external TVS diodes in handheld test equipment and consumer audio interfaces |
| Supply voltage range | 2.7–12 V single or ±3–±6 V dual - allows direct interfacing with 3.3 V logic and legacy ±5 V analog subsystems |
Pinout & Package
Package: 16-pin TSSOP (4.4 mm × 5.0 mm × 1.05 mm height), JEDEC MO-153 compliant, with 0.65 mm pitch and exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 15, 16 (IN1–IN4) | Digital control input | Active-high TTL/CMOS-compatible logic inputs; drive internal gate drivers for corresponding switches |
| 3, 4, 13, 14 (COM1–COM4) | Analog common terminal | Signal path connection point shared between NC/NO and switch channel; must remain within V− to V+ rails |
| 5, 6, 11, 12 (NC1–NC4) | Normally closed switch terminal | Connected to COM when IN = 0; open when IN = 1 - used for default-path fail-safe routing |
| 7 (V−) | Negative supply rail | Bias reference for dual-supply operation; clamps analog signals below V− via internal diodes |
| 8 (V+) | Positive supply rail | Primary analog power rail; sets upper limit of analog signal range and RON performance |
| 9 (GND) | Ground reference | Logic ground return; separate from analog COM paths to minimize digital noise coupling |
| 10 (VL) | Logic supply voltage | Independent 3–12 V rail for control logic - decouples switching speed from analog supply fluctuations |
| 11, 12, 13, 14 (NO1–NO4) | Normally open switch terminal | Connected to COM only when IN = 1; isolated otherwise - enables signal gating and channel selection |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 2 ns minimum delay prevents momentary shorting between NC and NO paths during transition - essential for fault-tolerant ATE and telecom line cards |
| Flat RON vs. signal voltage | ≤1.7 Ω variation across full 0–12 V analog range - maintains consistent gain and THD in audio DAC output switching |
| Low charge injection (38 pC) | Minimizes voltage glitch on high-impedance nodes (e.g., ADC sample capacitors), reducing settling error and calibration drift |
| TTL/CMOS logic compatibility | Accepts 0.8 V / 2.4 V thresholds with <1 μA input current - enables direct interface with FPGA I/O banks and microcontroller GPIOs without level shifters |
| 190 MHz -3 dB bandwidth | Supports composite video (NTSC/PAL), USB 1.1 signaling, and broadband RF test signal routing without amplitude roll-off |
Applications
| Automatic Test Equipment (ATE) | Data Acquisition Systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Higher RON (3.5 Ω typ), slower tON (75 ns), no dual-supply support - operates 3 V to 15 V single supply only | Less suitable for ±5 V legacy telecom systems; requires higher drive voltage for full analog range | Select when cost sensitivity outweighs speed/RON needs and dual-supply operation is unnecessary |
| ADG1414BRUZ | Lower RON (1.3 Ω typ), faster tON (25 ns), but requires ≥4.5 V supply - not functional at 3 V | Incompatible with battery-powered 3.3 V systems; superior for high-speed instrumentation above 4.5 V | Select when system uses ≥4.5 V supplies and demands lowest possible on-resistance and propagation delay |
Compared with MAX4617ESE+ and ADG1414BRUZ, the DG9424DQ-T1-E3 uniquely balances 3 V operability, dual-supply flexibility, and 1.7 Ω RON - making it optimal for portable test gear and mixed-voltage industrial controllers where supply headroom is constrained.

FAQ
What is the maximum analog signal voltage range supported by the DG9424DQ-T1-E3?
The DG9424DQ-T1-E3 supports 0 V to 12 V with single supply or ±3 V to ±6 V with dual supply. At ±5 V dual supply, the guaranteed analog signal range is ±5 V. Exceeding V+ or falling below V− triggers internal diode clamping - design must ensure signal excursions stay within (V− − 0.3 V) to (V+ + 0.3 V) per absolute maximum ratings.
Does the DG9424DQ-T1-E3 require external pull-up or pull-down resistors on its control inputs?
No, the DG9424DQ-T1-E3 does not require external biasing on IN1–IN4 pins. Its TTL/CMOS-compatible inputs draw <1 μA over temperature and recognize 0.8 V (low) and 2.4 V (high) thresholds. Direct connection to FPGA or MCU GPIOs is fully supported without additional components.
How does the DG9424DQ-T1-E3 differ from the DG9425DQ-T1-E3 and DG9426DQ-T1-E3?
The DG9424DQ-T1-E3 has active-high logic (ON when IN = 1), while DG9425DQ-T1-E3 uses active-low logic (ON when IN = 0). The DG9426DQ-T1-E3 integrates two normally open and two normally closed switches per package - unlike the DG9424DQ-T1-E3's four identical normally open configurations. Pinouts and supply requirements are identical across all three.
Can the DG9424DQ-T1-E3 operate reliably at 3.3 V supply?
Yes, the DG9424DQ-T1-E3 is fully specified down to 2.7 V single supply. At 3.3 V, RON rises to 13.8 Ω max (typ 8 Ω), tON increases to 163 ns typ, and analog range narrows to 0–3.3 V. All parameters remain guaranteed across -40 °C to +85 °C - validated in the datasheet's 3 V section (page 6).
Is thermal derating required for continuous operation of the DG9424DQ-T1-E3 in a 16-pin TSSOP package?
Yes - the DG9424DQ-T1-E3's power dissipation must be derated above 25 °C ambient. The datasheet specifies 7 mW/°C reduction beyond 25 °C, with a maximum package power dissipation of 450 mW at 25 °C and thermal resistance θJA = 178 °C/W. Layout must include adequate copper area under the exposed pad (if used) to meet junction temperature limits.
