Product details
Overview
DG442LEDJ-GE3 from Vishay Siliconix is a quad single-pole-single-throw (SPST) analog switch with normally open (NO) configuration, designed for precision signal routing in data acquisition and sample-and-hold circuits. It delivers 16 Ω typical on-resistance, 18 ns typical turn-on time, and <8 pC charge injection over full analog range, operating from +3 V to +16 V single supply or ±3 V to ±8 V dual supply.
For engineers reviewing the DG442LEDJ-GE3 datasheet, DG442LEDJ-GE3 pinout, DG442LEDJ-GE3 application, or DG442LEDJ-GE3 equivalent, key selection criteria include low leakage (<10 pA typ.), bidirectional conduction, TTL/CMOS compatibility, and TSSOP-16 package suitability for high-density PCB layouts in instrumentation and medical systems.
Technical Context
The DG442LEDJ-GE3 implements a monolithic CMOS analog switch architecture with four independent NO channels, each featuring matched RDS(on) (≤0.5 Ω max mismatch) and symmetrical conduction in both directions when enabled. Its charge injection is tightly controlled at 6.6 pC (typ.) under 12 V single-supply conditions, minimizing glitch energy in precision sampling paths.
It supports rail-to-rail analog signal switching up to supply rails (e.g., 0–12 V or ±5 V), with off-isolation of 68.4 dB and channel-to-channel crosstalk of 114 dB at 1 MHz - critical for multi-channel multiplexing where signal integrity across adjacent channels must be preserved.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 16 Ω typ. at 12 V - ensures minimal signal attenuation and gain error in precision amplifier input stages |
| Turn-on time | 18 ns typ. at 12 V - enables fast channel switching in high-throughput data acquisition systems |
| Charge injection | 6.6 pC typ. - limits voltage glitch on hold capacitors in sample-and-hold circuits to sub-mV levels |
| Analog signal range | 0 to 12 V (single supply) or ±5 V (dual supply) - supports full-rail operation without clamping in sensor front-ends |
| Off-leakage current | <1 nA max at 25 °C - preserves accuracy in high-impedance measurement nodes over temperature |
| Supply voltage range | +3 V to +16 V single or ±3 V to ±8 V dual - accommodates legacy industrial and modern low-voltage portable designs |
| Package | TSSOP-16 - provides 4.4 mm × 5.0 mm footprint with 0.65 mm pitch for compact, thermally efficient layouts |
Pinout & Package
Package: 16-lead TSSOP (JEDEC MS-012 compatible), body dimensions 5.00 mm × 4.40 mm × 1.20 mm, lead pitch 0.65 mm, moisture sensitivity level (MSL) 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (IN1–IN4) | Digital control inputs | Active-high logic: logic "1" ≥2.4 V enables switch; compatible with TTL/CMOS drivers |
| 5, 6, 12, 13 (S1–S4) | Source terminals | Analog inputs/outputs - bidirectional; connect to signal sources or loads |
| 7, 8, 11, 10 (D1–D4) | Drain terminals | Analog inputs/outputs - bidirectional; paired with Sx to form SPST NO switches |
| 9 (GND) | Ground reference | Logic ground and substrate reference; must be low-impedance for noise immunity |
| 14 (V−) | Negative supply | Required for dual-supply operation; tied to 0 V in single-supply mode |
| 16 (V+) | Positive supply | Primary power rail; sets analog signal range upper limit and RDS(on) performance |
| 15 (NC) | No-connect | Internally unconnected; must remain floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports signals from V− to V+ without distortion - essential for ±5 V sensor interfaces and unipolar 0–12 V industrial I/O |
| Low parasitic capacitance | CD(ON) = 15 pF, CS(OFF) = 5 pF - minimizes bandwidth degradation and coupling in RF-adjacent signal chains |
| Matched on-resistance | ΔRDS(on) ≤ 0.5 Ω - maintains channel-to-channel gain consistency in programmable-gain amplifiers |
| ESD robustness | 2500 V HBM - protects against handling damage during assembly and field service in test equipment |
| Wide temperature operation | –40 °C to +85 °C (D suffix) - qualified for industrial automation and medical diagnostics environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | 4-channel SPST NO, 1.8 Ω RDS(on), 33 V max supply, LFCSP-16 package | Better on-resistance and higher voltage rating; requires re-layout due to different footprint and thermal pad | Select when ultra-low RDS(on) and >16 V operation are required; verify PCB land pattern compatibility |
| MAX4617ESE+ | Quad SPST NO, 35 Ω RDS(on), 12 V max supply, SOIC-16 package | Higher on-resistance and narrower supply range; pin-compatible with SOIC-16 variant DG442LEDY-GE3 but not TSSOP | Choose for cost-sensitive industrial designs where 35 Ω RDS(on) is acceptable and SOIC-16 is preferred |
Compared with DG442LEDJ-GE3, ADG1412BRUZ offers lower on-resistance and wider voltage range but demands PCB redesign, while MAX4617ESE+ provides drop-in replacement only in SOIC-16 - making DG442LEDJ-GE3 optimal for space-constrained, mid-voltage precision routing where TSSOP density and 16 Ω performance are balanced.

FAQ
What is the maximum supply voltage rating for DG442LEDJ-GE3?
The DG442LEDJ-GE3 supports absolute maximum ratings of –0.3 V to +18 V between V+ and V–. For reliable operation, use within the recommended ranges: +3 V to +16 V single supply or ±3 V to ±8 V dual supply. Exceeding these may cause permanent damage or degraded RDS(on) performance.
Does DG442LEDJ-GE3 support bidirectional analog signal flow?
Yes, DG442LEDJ-GE3 supports fully bidirectional analog conduction when enabled - source (Sx) and drain (Dx) terminals are interchangeable. This allows flexible routing in both signal-source-to-load and load-to-sensor configurations without polarity constraints.
What is the typical charge injection value for DG442LEDJ-GE3 and why does it matter?
DG442LEDJ-GE3 has a typical charge injection of 6.6 pC at 12 V supply. This parameter quantifies the transient voltage glitch injected onto a hold capacitor during switching - critical in sample-and-hold and switched-capacitor circuits where even picocoulombs can cause measurable offset errors.
Is DG442LEDJ-GE3 RoHS-compliant and lead-free?
Yes, DG442LEDJ-GE3 is RoHS-compliant and lead-free, as indicated by the "-GE3" suffix per Vishay's ordering nomenclature. It meets JEDEC J-STD-020 moisture sensitivity level 1 and is qualified for lead-free reflow soldering per IPC/JEDEC J-STD-020.
How does DG442LEDJ-GE3 differ from DG441LEDJ-GE3?
DG442LEDJ-GE3 is a normally open (NO) quad SPST switch, while DG441LEDJ-GE3 is normally closed (NC). Their truth tables are inverted: logic "1" turns DG442LEDJ-GE3 ON and DG441LEDJ-GE3 OFF. All electrical specs (RDS(on), tON, charge injection) are identical; only default state differs.
