Product details
Overview
DG412LEDJ-GE3 from Vishay Siliconix is a quad SPST analog switch with complementary logic control (active-low enable), 16 Ω on-resistance, 15 pF channel-on capacitance, and ±5 V / +12 V dual/single supply operation. It routes audio, sensor, or instrumentation signals in data acquisition systems where low charge injection (<8 pC) and fast switching (tON = 16 ns) are critical.
For engineers reviewing the DG412LEDJ-GE3 datasheet, DG412LEDJ-GE3 pinout, DG412LEDJ-GE3 application, or DG412LEDJ-GE3 equivalent, this page delivers verified electrical specs, package dimensions, truth table behavior, real-world use cases, and validated alternative parts for signal routing design-in.
Technical Context
The DG412LEDJ-GE3 implements four independent NMOS/PMOS transmission gates with rail-to-rail analog signal handling (–5 V to +5 V on dual supply, 0 V to +12 V on single supply). Its complementary logic input (IN active-low) ensures deterministic switching when driven by TTL/CMOS levels (VIL ≤ 0.8 V, VIH ≥ 2.4 V).
Each switch exhibits symmetrical conduction (bidirectional), sub-10 pC charge injection over full signal swing, and <1 nA off-state leakage at +85 °C. The device supports break-before-make timing only in DG413LE variants - DG412LEDJ-GE3 operates as four independent SPST switches without inter-channel timing coordination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 16 Ω max at +25 °C, +12 V supply - ensures minimal signal attenuation and voltage drop in precision analog paths |
| Channel-on capacitance | 15 pF typical - limits high-frequency bandwidth degradation and crosstalk in multi-channel routing |
| Charge injection | 6.6 pC typical - reduces glitch-induced error in sample-and-hold or ADC front-end circuits |
| Turn-on time | 16 ns typical at +12 V - enables high-speed multiplexing in automated test equipment (ATE) |
| Analog signal range | ±5 V (dual), 0–12 V (single) - supports bipolar sensor outputs and unipolar microcontroller I/O interfaces |
| Supply voltage range | +3 V to +16 V single or ±3 V to ±8 V dual - allows flexible integration into mixed-voltage industrial and portable systems |
| Logic compatibility | TTL/CMOS - simplifies interface with FPGA, MCU, or ASIC control without level-shifting circuitry |
Pinout & Package
Package: 16-pin TSSOP (JEDEC MS-012, body size 5.0 × 4.4 mm, 0.65 mm pitch). RoHS-compliant, lead (Pb)-free, halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 (IN1–IN4) | Digital control input (active-low) | Drives corresponding switch ON when logic low (≤0.8 V); complements DG411LE's active-high logic |
| 2, 6, 10, 14 (S1–S4) | Source terminal | Analog input/output node; bidirectional conduction path when switch is enabled |
| 3, 7, 11, 15 (D1–D4) | Drain terminal | Analog input/output node; electrically identical to source under ON condition |
| 4 (V+) | Positive supply rail | Bias for internal PMOS devices; sets upper analog signal limit (up to +16 V) |
| 8 (V−) | Negative supply rail | Bias for internal NMOS devices; sets lower analog signal limit (down to –8 V) |
| 12 (GND) | Ground reference | Return path for logic and substrate bias; must be low-impedance for noise immunity |
| 16 (VL) | Logic supply reference | Defines logic threshold; tied to V+ if V+ ≤ 5 V, else fixed at 5 V for stable TTL/CMOS compatibility |
Key Features

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 |
|---|---|---|---|
| MAX4612ESE+ | 18 Ω RDS(on), 12 ns tON, SO-16 package only, no TSSOP option | Higher speed but narrower supply range (±4.5 V max dual); less suitable for +12 V single-supply systems | Select when tON < 15 ns is mandatory and layout uses SOIC; verify VL pin compatibility with 5 V logic rails |
| ADG1412YRUZ | 1.8 Ω RDS(on), 200 MHz bandwidth, 10 pC charge injection, higher cost | Optimized for high-precision, high-bandwidth applications (e.g., RF test); over-spec'd for general-purpose ATE | Choose for sub-2 Ω on-resistance requirements in metrology-grade systems; avoid for cost-sensitive industrial DAQ |
Compared with DG412LEDJ-GE3, MAX4612ESE+ offers faster switching but sacrifices supply flexibility, while ADG1412YRUZ delivers ultra-low on-resistance at significantly higher cost and complexity-making DG412LEDJ-GE3 the optimal balance of speed, voltage range, leakage, and TSSOP footprint for mid-performance analog routing.

FAQ
What logic polarity does the DG412LEDJ-GE3 use for switch control?
The DG412LEDJ-GE3 uses active-low logic control: each INx pin must be driven to ≤0.8 V to turn its corresponding switch ON, and to ≥2.4 V to turn it OFF. This complements the DG411LE's active-high logic, allowing direct interface with open-collector or inverted control buses without external inverters. DG412LEDJ-GE3's truth table is explicitly defined in Vishay's E25-0357 Rev. D datasheet.
Can DG412LEDJ-GE3 operate from a single +5 V supply?
Yes, DG412LEDJ-GE3 supports single +5 V operation with an analog signal range of 0 V to +5 V and typical on-resistance of 36 Ω. At +5 V, tON is 27 ns and charge injection drops to 3.3 pC - making it viable for low-voltage portable instrumentation. Full specifications across temperature are guaranteed per the D-suffix rating (–40 °C to +85 °C).
Does DG412LEDJ-GE3 support break-before-make switching?
No, DG412LEDJ-GE3 does not implement break-before-make functionality. It consists of four independent SPST switches with no internal timing coordination between channels. Break-before-make behavior is exclusive to the DG413LE variant, which integrates two NO and two NC switches in configurable SPDT/DPDT topologies. DG412LEDJ-GE3 must be externally controlled to prevent simultaneous conduction.
What is the maximum analog signal voltage DG412LEDJ-GE3 can handle?
DG412LEDJ-GE3 supports analog signals from V− to V+, with absolute maximum ratings of –0.3 V to (V+) + 0.3 V on all S/D pins. With ±5 V dual supplies, the safe analog range is –5 V to +5 V; with +12 V single supply, it is 0 V to +12 V. Exceeding these clamps internal protection diodes - sustained overvoltage risks permanent damage per Absolute Maximum Ratings in E25-0357 Rev. D.
Is DG412LEDJ-GE3 pin-compatible with other DG4xxLE variants?
Yes, DG412LEDJ-GE3 shares identical 16-pin TSSOP pinout and package dimensions with DG411LE and DG413LE variants. All three devices use the same pin assignments for INx, Sx, Dx, V+, V−, GND, and VL. However, logic polarity (DG411LE = active-high, DG412LE = active-low, DG413LE = mixed NO/NC) and internal switch configuration differ - PCB layout is reusable, but firmware/control logic must match the selected variant's truth table.
