Product details
Overview
DG9408DN-T1-E4 from Vishay Siliconix is an 8-channel single-ended analog multiplexer IC designed to route one of eight analog inputs to a common output under 3-bit binary address control (A0–A2). It operates on single supplies from 3 V to 12 V or dual supplies ±3 V to ±6 V, features 3.9 Ω typical on-resistance, 42 ns enable turn-on time, and break-before-make switching-ideal for precision data acquisition in battery-powered test equipment.
For engineers reviewing the DG9408DN-T1-E4 datasheet, DG9408DN-T1-E4 pinout, DG9408DN-T1-E4 application, or DG9408DN-T1-E4 equivalent, key selection criteria include its QFN16 package, guaranteed break-before-make timing, low 29 pC charge injection at 12 V supply, and compatibility with 3 V TTL/CMOS logic levels.
Technical Context
The DG9408DN-T1-E4 uses BiCMOS wafer fabrication to achieve low on-resistance flatness (8 Ω max), high off-isolation (–80 dB at 100 kHz), and fast transition times (75 ns max at 12 V). Its decoder/driver includes level-shifting circuitry enabling direct interface with 3 V logic while operating across wide analog signal ranges (0–12 V single-supply or ±5 V dual-supply).
Break-before-make timing is guaranteed (2–24 ns) to prevent crosstalk during channel switching. Internal clamping diodes protect inputs against overvoltage transients up to ±0.3 V beyond supply rails, and ESD robustness reaches 2000 V HBM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | 0–12 V (single supply); supports full-rail input/output swing without distortion |
| On-Resistance (RON) | 4–7.5 Ω (min–max at 12 V); enables <1 LSB error in 12-bit systems with 1 kΩ source impedance |
| Enable Turn-On Time (tON(EN)) | 42–75 ns (typ–max at 12 V); supports >10 MSPS multiplexed sampling rates |
| Charge Injection | 29 pC (typ at 12 V); limits voltage glitch to <3 mV on 10 nF hold capacitors |
| Off Isolation (OIRR) | –80 dB (min at 100 kHz); suppresses adjacent-channel crosstalk below –80 dB in audio routing |
| Supply Voltage Range | 3–12 V single or ±3 V to ±6 V dual; allows operation from Li-ion battery (3.0–4.2 V) or regulated 5 V/±5 V rails |
| Logic Compatibility | TTL/CMOS/LV logic (3 V); interfaces directly with microcontroller GPIOs without level shifters |
Pinout & Package
Package: 16-pin QFN (4 mm × 4 mm), lead (Pb)-free with nickel-palladium-gold terminations, MSL3, JEDEC-compliant reflow profile.

| 9, 10, 11, 12 | A0, A1, A2, EN digital controls | 3-bit address + active-low enable; all CMOS-compatible with 0.8 V/2.4 V thresholds at 12 V supply |
| 13, 14 | V+, V− power rails | Separate analog supply pins; support single or dual supply configurations with independent ground reference |
| 15 | D analog output | Common drain node; routed to selected Sx input when enabled; low-capacitance (238 pF typ) minimizes settling time |
| 16 | GND | Ground reference for logic and substrate; must be low-impedance connection to minimize noise coupling |

FAQ
What is the maximum analog signal voltage range supported by DG9408DN-T1-E4?
DG9408DN-T1-E4 supports 0–12 V analog signal range with single 12 V supply, or ±5 V with dual ±5 V supply. Inputs exceeding V+ or V− are clamped by internal diodes; forward current must be limited to rated values. The device maintains specified RON and leakage performance across these full ranges, as verified in the Absolute Maximum Ratings and Single Supply 12 V specifications tables.
Does DG9408DN-T1-E4 require external pull-up resistors on its address or enable pins?
No, DG9408DN-T1-E4 does not require external pull-up resistors. Its digital inputs (A0, A1, A2, EN) have CMOS-compatible thresholds (0.8 V low, 2.4 V high at 12 V supply) and input leakage ≤±1 µA. Microcontroller GPIOs driving these pins directly meet logic level requirements without additional biasing-confirmed in the Digital Control section of the datasheet.
How is break-before-make timing guaranteed in DG9408DN-T1-E4?
DG9408DN-T1-E4 guarantees break-before-make timing of 2–24 ns across temperature and supply conditions, as measured per Figure 4 test circuit. This is achieved through internal timing control in the decoder/driver block-not dependent on external RC networks. The guarantee applies to all channel transitions and is validated in production testing per the specifications table.
Can DG9408DN-T1-E4 operate from a single 3 V supply with 3 V logic levels?
Yes, DG9408DN-T1-E4 operates from a single 3 V supply with logic thresholds of 0.4 V (low) and 1.8 V (high), matching standard 3 V CMOS levels. At 3 V, RON rises to 12–26.5 Ω and switching times increase (e.g., tON(EN) = 140–178 ns), but all functions remain fully specified-verified in the Single Supply 3 V specifications table.
What thermal derating applies to DG9408DN-T1-E4 above 70 °C ambient?
DG9408DN-T1-E4 has a power dissipation rating of 1880 mW at 70 °C ambient. Above this temperature, derating is 23.5 mW/°C, as stated in the Absolute Maximum Ratings table. At 85 °C ambient, maximum allowable power drops to 1522 mW. This linear derating ensures safe operation within silicon junction temperature limits under sustained load.
