Product details
Overview
DG418BDQ-T1-E3 from Vishay Siliconix is a precision monolithic SPST CMOS analog switch optimized for bidirectional signal routing in low-leakage, high-accuracy applications. It features 15 Ω on-resistance, ±15 V analog signal range, 110 ns turn-on time, TTL/CMOS-compatible control, and operates from –40 °C to +85 °C - ideal for battery-powered instrumentation and sample-and-hold circuits.
For engineers reviewing the DG418BDQ-T1-E3 datasheet, DG418BDQ-T1-E3 pinout, DG418BDQ-T1-E3 application, or DG418BDQ-T1-E3 equivalent, key selection criteria include guaranteed break-before-make timing (in DG419B only), channel leakage <±0.25 nA at full temperature range, MSOP-8 footprint compatibility, and HVSG process–enabled high-voltage tolerance up to ±20 V.
Technical Context
The DG418BDQ-T1-E3 implements a single-pole, single-throw (SPST) switch topology with complementary control logic versus DG417B: logic high (≥2.4 V) disables conduction, while logic low (≤0.8 V) enables the channel. Its high-voltage silicon gate (HVSG) process ensures robust operation across ±15 V dual supplies or 0–12 V single supply, with epitaxial layer latchup protection.
Each channel conducts equally in both directions when on and blocks signals up to the supply rails when off. Charge injection is specified at 38 pC (±15 V), off-isolation reaches –82 dB at 1 MHz, and crosstalk remains below –88 dB for DG419B - though DG418B itself is not rated for crosstalk or break-before-make.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-rail analog signals without clipping in dual-supply systems |
| RDS(on) | 15 Ω typical - minimizes signal attenuation and gain error in precision signal paths |
| tON | 110 ns max - enables fast multiplexing in data acquisition and test equipment |
| IS(off) | ±0.25 nA max at full temperature - preserves accuracy in high-impedance sensor interfaces |
| Supply Voltage Range | V+ = 20 V, V− = −20 V - withstands transient overvoltage events per absolute maximum rating |
| Logic Compatibility | TTL and CMOS - simplifies interface with microcontrollers and FPGAs without level-shifting |
| Package | MSOP-8 - 3.0 × 4.9 mm footprint saves board space in portable and dense PCB layouts |
Pinout & Package
DG418BDQ-T1-E3 is housed in an 8-pin MSOP package (JEDEC MO-187, variation AA/BA), measuring 3.0 mm × 4.9 mm × 1.10 mm max height, with gull-wing leads and exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital control input | Active-low enable: logic low (≤0.8 V) turns switch ON; logic high (≥2.4 V) turns OFF |
| 2 (S) | Source terminal | Bidirectional analog node - connects to signal source or load depending on system topology |
| 3 (D) | Drain terminal | Bidirectional analog node - completes switched path with S; interchangeable in conduction |
| 4 (V−) | Negative supply rail | Reference for negative analog swing; must be ≥ –20 V per absolute maximum rating |
| 5 (GND) | Ground reference | Logic ground and substrate reference; separate from analog ground in mixed-signal designs |
| 6 (V+) | Positive supply rail | Reference for positive analog swing; must be ≤ +20 V per absolute maximum rating |
| 7 (VL) | Logic supply voltage | Independent 5 V logic rail - decouples switching threshold from analog supply noise |
| 8 (NC) | No connect | Internally unconnected; must remain floating - no external tie or pull-up/pull-down |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage silicon gate (HVSG) process | Enables ±15 V analog signal handling and >10⁹ Ω off-isolation without external clamping |
| Low on-resistance flatness | 15 Ω typical with <2 Ω variation over ±10 V signal range - maintains linearity in audio and sensor paths |
| Ultra-low leakage | ±0.25 nA max off-leakage at 85 °C - critical for long-interval sample-and-hold and high-Z transducer interfaces |
| Fast, controlled switching | 110 ns tON/80 ns tOFF with 89 ns transition time - reduces settling errors in multi-channel DAQ systems |
| RoHS-compliant MSOP-8 | Lead-free terminations (Pb-free), 3.0 × 4.9 mm body - meets industrial environmental requirements and space constraints |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUA+ | Single SPST, 35 Ω RDS(on), 100 ns tON, ±15 V range, µMAX-8 package | Higher on-resistance increases gain error; same MSOP footprint but different pinout (IN/S/D swapped) | Select when lower cost is prioritized over precision; verify PCB layout compatibility due to pin reordering. |
| ADG1419BRMZ | SPDT configuration, 1.3 Ω RDS(on), 200 ns tON, ±15 V, 10 V logic-compatible, 10-lead MSOP | SPDT vs SPST topology requires redesign; lower RDS(on) improves accuracy but adds complexity | Choose for ultra-low on-resistance needs where SPDT functionality is acceptable and extra pin count is manageable. |
Compared with MAX4617EUA+ and ADG1419BRMZ, DG418BDQ-T1-E3 delivers superior on-resistance flatness and lower leakage in SPST form factor, making it optimal for high-accuracy, low-power, space-constrained analog routing - especially where pinout compatibility with legacy DG4xxB designs is required.

FAQ
What is the maximum analog signal voltage supported by DG418BDQ-T1-E3?
DG418BDQ-T1-E3 supports analog signals from V− to V+, with absolute maximum ratings of V− = −20 V and V+ = +20 V. Under normal operation with ±15 V supplies, its guaranteed analog signal range is ±15 V - meaning signals between −15 V and +15 V pass through with minimal distortion and no rail clamping.
Does DG418BDQ-T1-E3 have break-before-make functionality?
No, DG418BDQ-T1-E3 does not provide break-before-make switching. That feature is explicitly guaranteed only for the DG419B (SPDT) variant. DG418BDQ-T1-E3 is an SPST device with independent on/off control per channel and no internal timing coordination between states.
What is the logic polarity of DG418BDQ-T1-E3 compared to DG417B?
DG418BDQ-T1-E3 uses active-low logic control: a logic low (≤0.8 V) on the IN pin turns the switch ON, while a logic high (≥2.4 V) turns it OFF. This is the inverse of DG417B, which is active-high - a key distinction confirmed in the truth table of the DG417B/DG418B datasheet.
Can DG418BDQ-T1-E3 operate from a single 12 V supply?
Yes, DG418BDQ-T1-E3 supports single-supply operation. With V+ = 12 V and V− = 0 V, its analog signal range is 0–12 V, RDS(on) rises to 26 Ω typical, and tON increases to 100 ns - all verified in the datasheet's single-supply specification table.
Is the NC pin (Pin 8) required to be left floating on DG418BDQ-T1-E3?
Yes, Pin 8 is designated NC (no connect) and must remain unconnected - neither tied to ground, supply, nor any other node. Internal connection is absent, and routing or biasing this pin may induce parasitic coupling or violate package reliability specifications per Vishay's MSOP mechanical drawings.
