Product details

Overview

DG412LEDQ-T1-GE3 from Vishay Siliconix is a monolithic quad single-pole-single-throw (SPST) analog switch with complementary logic control, designed for precision signal routing in instrumentation and data acquisition systems. It delivers 16 Ω on-resistance, 15 pF channel-on capacitance, 9 ns turn-off time, and operates from +3 V to +16 V single supply or ±3 V to ±8 V dual supply - enabling low-distortion switching in medical sensors and automated test equipment.

For engineers reviewing the DG412LEDQ-T1-GE3 datasheet, DG412LEDQ-T1-GE3 pinout, DG412LEDQ-T1-GE3 application, or DG412LEDQ-T1-GE3 equivalent, key selection criteria include guaranteed 16 Ω R_DS(on) at 12 V, sub-8 pC charge injection, TTL/CMOS-compatible control inputs, and TSSOP-16 package compatibility with high-density PCB layouts.

Technical Context

The DG412LEDQ-T1-GE3 implements four independent bidirectional SPST switches with active-high logic control (INx = "1" → ON), contrasting with the DG411LE's active-low configuration. Each switch supports rail-to-rail analog signal handling up to supply rails and maintains symmetrical conduction in both directions when enabled.

Its internal architecture includes integrated level-shifting circuitry referenced to VL (logic supply), allowing logic inputs to operate at 3 V, 5 V, or matched to V+ while maintaining full analog swing compliance. Switching performance is characterized across temperature (–40 °C to +85 °C) and supply conditions, with leakage currents specified ≤ ±10 nA over full operating range.

Key Specifications

Parameter	Value and Actual Design Meaning
On-resistance	16 Ω typical at V+ = 12 V - ensures minimal signal attenuation and voltage drop in precision analog paths
Channel-on capacitance	15 pF - reduces high-frequency signal loading and preserves bandwidth in audio/video routing
Charge injection	≤ 8 pC - minimizes DC offset errors in sample-and-hold and multiplexed ADC front-ends
Turn-off time	9 ns typical - enables fast channel switching in high-speed data acquisition systems
Analog signal range	0 to 12 V (single supply) or ±5 V (dual supply) - supports full-rail operation without clipping
Logic compatibility	TTL/CMOS - interfaces directly with microcontrollers and FPGAs without level-shifting circuitry
Off-isolation	68 dB at 1 MHz - suppresses crosstalk between adjacent channels in multi-signal systems

Pinout & Package

Package: 16-lead TSSOP (JEDEC MS-012, body dimensions 5.0 × 4.4 × 1.2 mm). Pin pitch: 0.65 mm. RoHS-compliant, lead (Pb)-free termination.

Pin/Terminal	Circuit Role	Design Meaning
IN1–IN4	Digital control input	Active-high logic: INx = ≥2.4 V → corresponding switch ON; compatible with 3 V/5 V logic families
S1–S4	Source terminal	Analog input/output node - bidirectional, supports signal flow in either direction when switch is closed
D1–D4	Drain terminal	Analog input/output node - electrically identical to Sx; paired with Sx to form SPST path
V+	Positive analog supply	Accepts 3 V to 16 V (single) or +3 V to +8 V (dual); powers analog channel core
V−	Negative analog supply	Required for dual-supply operation (±3 V to ±8 V); sets lower analog rail
GND	Analog ground reference	Common return for analog signals and substrate bias; separate from digital ground in mixed-signal designs
VL	Logic supply reference	Defines logic threshold; may be tied to V+ (if ≤5 V) or external 3 V/5 V source for level-shifted control

Key Features

Feature	Design Value
Rail-to-rail analog switching	Supports signal voltages from V− to V+ without distortion - critical for sensor interfaces and DAC outputs
Low charge injection	6.6 pC typical - prevents settling errors in high-impedance sampling circuits and precision integrators
Fast switching with low glitch	t_ON = 16 ns, t_OFF = 9 ns - enables >10 MSPS multiplexing in data acquisition with minimal transient energy
Low parasitic capacitance	C_S(off) = 5 pF, C_D(off) = 6 pF - isolates off-channels effectively, reducing capacitive feedthrough in RF-adjacent layouts
Wide supply flexibility	Operates from 3 V single supply up to ±8 V dual supply - simplifies power architecture in portable and industrial 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
ADG1412BRUZ	Higher on-resistance (1.8 Ω typical at ±15 V), wider supply (±5 V to ±16.5 V), but requires negative logic for same function	Better suited for high-voltage industrial control; not drop-in due to different logic polarity and pinout	Select if higher supply voltage tolerance and lower R_ON at ±15 V are required; verify control logic inversion and layout adaptation
TS5A3157DCKR	Lower voltage rating (up to 5.5 V), smaller 6-pin SC70 package, 0.7 Ω R_DS(on), but only single-channel	Optimized for space-constrained battery-powered devices; quad implementation requires four devices	Choose for ultra-low-power, low-voltage portable designs where board area is critical and quad integration is not mandatory

Compared with ADG1412BRUZ and TS5A3157DCKR, DG412LEDQ-T1-GE3 provides balanced performance across 3–16 V operation, guaranteed 16 Ω R_DS(on), and native quad integration in TSSOP-16 - making it optimal for mid-range industrial and medical signal routing where supply flexibility and channel density are prioritized over extreme low-R_ON or ultra-miniaturization.

FAQ

What is the maximum supply voltage rating for DG412LEDQ-T1-GE3?

The DG412LEDQ-T1-GE3 supports absolute maximum ratings of –0.3 V to +18 V between V+ and V−, with recommended operating ranges of +3 V to +16 V (single supply) or ±3 V to ±8 V (dual supply). Exceeding +16 V or –8 V risks permanent damage and violates the device's safe operating area as defined in Vishay's Absolute Maximum Ratings table.

Does DG412LEDQ-T1-GE3 support bidirectional analog signal flow?

Yes, DG412LEDQ-T1-GE3 supports fully bidirectional analog signal flow on all four SPST channels. When enabled, each S–D pair conducts equally well in either direction, with symmetric on-resistance and capacitance characteristics - enabling use in both source-to-drain and drain-to-source signal paths without performance penalty.

How does the VL pin function in DG412LEDQ-T1-GE3?

The VL pin on DG412LEDQ-T1-GE3 sets the logic threshold reference for IN1–IN4 inputs. It may be tied to V+ (if V+ ≤ 5 V) or driven by an external 3 V/5 V supply to ensure proper TTL/CMOS recognition. This allows independent optimization of logic interface voltage without affecting analog rail definitions on V+ and V−.

What is the guaranteed maximum on-resistance for DG412LEDQ-T1-GE3 at 5 V supply?

At V+ = 5 V, DG412LEDQ-T1-GE3 guarantees a maximum on-resistance of 50 Ω over the full operating temperature range (–40 °C to +85 °C), with typical value of 36 Ω at room temperature. This specification is validated under IS = 5 mA and VD = 1 V or 3.5 V, per Vishay's official datasheet Section 3 (Single Supply 5 V specifications).

Is DG412LEDQ-T1-GE3 pin-compatible with DG411LEDQ-T1-GE3?

No, DG412LEDQ-T1-GE3 is not pin-compatible with DG411LEDQ-T1-GE3 in terms of logic behavior - though both share identical pinout and package (TSSOP-16). DG412LEDQ-T1-GE3 uses active-high logic (INx = "1" → ON), whereas DG411LEDQ-T1-GE3 uses active-low logic (INx = "0" → ON). Swapping them requires inverting control signals or redesigning firmware logic.
