Product details
Overview
DG412LEDY-GE3 from Vishay Siliconix is a quad SPST analog switch with complementary logic control, designed for signal routing in precision instrumentation and data acquisition systems. It delivers 16 Ω on-resistance, 15 pF channel-on capacitance, <8 pC charge injection, and operates from 3 V to 16 V single supply or ±3 V to ±8 V dual supply - enabling low-distortion switching in battery-powered medical sensors.
For engineers reviewing the DG412LEDY-GE3 datasheet, DG412LEDY-GE3 pinout, DG412LEDY-GE3 application, or DG412LEDY-GE3 equivalent, key selection criteria include its complementary logic behavior (IN high = switch off), SOIC-16 package thermal performance (650 mW at 25 °C), and guaranteed leakage ≤10 nA over –40 °C to +85 °C.
Technical Context
The DG412LEDY-GE3 implements four independent transmission-gate switches with CMOS/TTL-compatible digital inputs and rail-to-rail analog signal handling. Its complementary logic architecture ensures that a logic high (≥2.4 V) disables all channels, while logic low (≤0.8 V) enables conduction - directly opposing the DG411LE's control polarity.
It supports bidirectional analog signal flow with matched on-resistance across temperature and supply voltage, and integrates internal ESD protection (2500 V HBM). The device maintains consistent dynamic performance: tON ≤ 50 ns and tOFF ≤ 30 ns under 12 V single-supply conditions with 300 Ω load and 35 pF capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 16 Ω typical at 12 V supply - ensures minimal signal attenuation and voltage drop in precision sensor front-ends |
| Channel-on capacitance | 15 pF - limits high-frequency crosstalk and preserves bandwidth in audio/video routing |
| Charge injection | ≤8 pC - prevents DC offset errors in sampling circuits and integrators |
| Switching time | tON ≤ 50 ns, tOFF ≤ 30 ns - enables fast multiplexing in 20+ MSPS data acquisition |
| Analog signal range | 0 to 12 V (single supply) or ±5 V (dual supply) - supports full-rail operation without clipping |
| Supply voltage range | 3–16 V single or ±3–±8 V dual - accommodates portable (3 V), industrial (12 V), and bipolar signal conditioning |
| Leakage current | ≤10 nA max at +85 °C - critical for high-impedance pH or thermocouple measurement paths |
Pinout & Package
Package: 16-pin SOIC (narrow body, 3.9 mm width), JEDEC MS-012 compliant, with 1.27 mm pitch and 650 mW power dissipation rating at 25 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 (IN1–IN4) | Digital control input | Active-low logic: IN = low enables switch; compatible with 3.3 V/5 V microcontrollers |
| 2, 6, 10, 14 (S1–S4) | Source terminal | Analog input/output node; bidirectional, rail-to-rail capable |
| 3, 7, 11, 15 (D1–D4) | Drain terminal | Analog input/output node; matched impedance and capacitance to S pins |
| 4 (V+) | Positive supply | Accepts 3–16 V single supply or +3 to +8 V in dual-supply mode |
| 8 (V−) | Negative supply | Ground (0 V) for single supply; –3 to –8 V for dual-supply operation |
| 12 (GND) | Signal ground reference | Return path for logic and analog sections; separate from power ground in mixed-signal layouts |
| 16 (VL) | Logic supply | Accepts 3–5 V logic-level reference; decouples logic threshold from analog supply rails |

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 |
|---|---|---|---|
| ADG1412BRUZ | Higher on-resistance (1.8 Ω typical), wider supply (±15 V), but larger TSSOP-16 package | Better suited for high-voltage industrial I/O; less optimal for low-voltage portable designs | Select when ±15 V operation or lower RDS(on) is required; not pin-compatible |
| DG411LEDY-GE3 | Same package and pinout, but inverted logic (IN high = on); identical RDS(on), capacitance, and leakage specs | Direct replacement where active-high control is preferred and board layout allows logic inversion | Choose for logic polarity alignment; requires no schematic change beyond control signal inversion |
Compared with ADG1412BRUZ and DG411LEDY-GE3, the DG412LEDY-GE3 provides optimal balance of low on-resistance, ultra-low charge injection, and SOIC-16 footprint for cost-sensitive, space-constrained instrumentation - without requiring voltage translation or PCB redesign.

FAQ
What is the logic polarity of DG412LEDY-GE3?
The DG412LEDY-GE3 uses complementary (active-low) logic: a logic low (≤0.8 V) on IN1–IN4 enables the corresponding switch, while a logic high (≥2.4 V) disables it. This is the inverse of DG411LEDY-GE3 and is confirmed in the truth table on page 2 of Vishay document 78091. DG412LEDY-GE3 maintains this behavior across its full operating temperature range of –40 °C to +85 °C.
Can DG412LEDY-GE3 operate from a 3.3 V single supply?
Yes, DG412LEDY-GE3 is fully specified down to 3 V single supply, with RDS(on) ≤ 90 Ω, tON ≤ 85 ns, and leakage ≤10 nA at +85 °C. Its VL pin accepts 3 V logic levels, and input thresholds (VIL ≤ 0.4 V, VIH ≥ 2.0 V at 3 V supply) ensure reliable operation with 3.3 V microcontrollers. DG412LEDY-GE3 retains rail-to-rail analog switching from 0 V to 3 V.
Is DG412LEDY-GE3 pin-compatible with DG411LEDY-GE3?
Yes, DG412LEDY-GE3 and DG411LEDY-GE3 share identical SOIC-16 pinout, package dimensions, and electrical specifications except for logic polarity. Both have the same pin assignments for INx, Sx, Dx, V+, V−, GND, and VL. DG412LEDY-GE3 can replace DG411LEDY-GE3 on the same PCB if the control logic is inverted - no layout changes are needed.
What is the maximum analog signal voltage DG412LEDY-GE3 can handle?
DG412LEDY-GE3 supports analog signals from 0 V to V+ in single-supply mode or from V− to V+ in dual-supply mode. With 12 V single supply, the full analog range is 0–12 V; with ±5 V dual supply, it is –5 V to +5 V. Signals exceeding these rails are clamped by internal diodes - per Absolute Maximum Ratings, analog inputs must stay within –0.3 V to (V+) +0.3 V to avoid damage. DG412LEDY-GE3 guarantees safe operation across its full specified temperature range.
Does DG412LEDY-GE3 require an external logic supply (VL)?
Yes, DG412LEDY-GE3 requires a dedicated VL supply (pin 16) to set logic threshold levels independently of analog supplies. VL must be 3–5 V and is typically tied to the host controller's I/O voltage. This decoupling ensures consistent switching behavior even when V+ varies (e.g., battery discharge). DG412LEDY-GE3 specifies IL ≤ 1 μA, minimizing power impact. Omitting VL violates the recommended operating conditions and may cause erratic control.
