Product details
Overview
DG442LDY-T1-E3 from Vishay Siliconix is a precision monolithic quad SPST low-voltage CMOS analog switch with break-before-make switching action, 20 ns turn-on time, 12 ns turn-off time, and 17 Ω on-resistance - used in precision data acquisition and audio/video signal routing where low distortion and high channel isolation are required.
For engineers reviewing the DG442LDY-T1-E3 datasheet, DG442LDY-T1-E3 pinout, DG442LDY-T1-E3 application, or DG442LDY-T1-E3 equivalent, key selection criteria include single/dual supply flexibility (2.7–12 V or ±3–±6 V), 0.25 nA leakage, 2000 V ESD protection, and TSSOP/SOIC package compatibility for space-constrained mixed-signal PCBs.
Technical Context
The DG442LDY-T1-E3 implements complementary CMOS switch architecture with BiCMOS fabrication, enabling rail-to-rail analog signal handling across its full supply range. Its control logic is inverted relative to DG441L: logic high disables all switches, logic low enables them.
It delivers flat RDS(on) over signal range (±5 V dual supply or 0–12 V single supply), minimal charge injection (5 pC), and high-frequency performance with –3 dB bandwidth of 280 MHz and off-isolation of –50 dB at 50 MHz - optimized for low-crosstalk multiplexing in precision instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 17 Ω typical at 12 V single supply - ensures minimal signal attenuation and gain error in precision amplifier gain-switching circuits |
| Turn-on / Turn-off time | 20 ns / 12 ns at 12 V - supports high-speed multiplexing in automated test equipment sampling paths |
| Analog signal range | 0 to 12 V (single) or ±5 V (dual) - enables direct interfacing with industrial sensors and op-amp rails without level-shifting |
| Leakage current | 0.25 nA max at 25 °C - preserves accuracy in high-impedance sample-and-hold and sensor front-end applications |
| ESD protection | 2000 V HBM - reduces need for external transient suppression in portable and field-deployable systems |
| Off-isolation | –50 dB at 50 MHz - prevents signal coupling between channels in multi-source video/audio routing |
| Supply range | 2.7–12 V single or ±3–±6 V dual - allows operation from Li-ion batteries or standard lab power rails |
Pinout & Package
16-pin narrow-body SOIC (JEDEC MS-012), 10.0 mm × 4.0 mm × 1.75 mm body height, 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | Inverted logic: low = switch closed; compatible with TTL/CMOS drivers without level translation |
| S1–S4 | Source terminals | Low-impedance analog inputs/outputs; connected to load or signal source in SPST configuration |
| D1–D4 | Drain terminals | Switched analog outputs/inputs; symmetric conduction path with Sx for bidirectional signal routing |
| V+ | Positive supply | Accepts 2.7–12 V single or +3–+6 V dual supply; powers internal logic and switch driver stages |
| V− | Negative supply | Required for dual-supply operation (–3 to –6 V); enables true bipolar analog signal handling |
| GND | Ground reference | Logic and analog return; must be low-impedance to minimize crosstalk and switching noise |
| NC | No connect | Internally unconnected pin; must remain floating - no PCB trace or thermal pad connection |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Full 0–12 V or ±5 V signal range preserved without clipping - eliminates need for external bias networks |
| Break-before-make action | Guaranteed non-overlapping conduction prevents momentary shorting in gain-programmable amplifier configurations |
| Low charge injection (5 pC) | Minimizes voltage glitch on hold capacitors - critical for sub-12-bit accuracy in open-loop sample-and-hold circuits |
| High off-isolation (–50 dB @ 50 MHz) | Enables clean separation of RF and baseband signals in SDSL/DSLAM line card designs |
| TTL/CMOS input compatibility | Direct interface with microcontroller GPIO or FPGA I/O banks - no external pull-ups or level shifters required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4618ESE+ | Higher RDS(on) (35 Ω typ), slower tON (45 ns), same SOIC-16 package | Lower bandwidth (–3 dB at 120 MHz); less suitable for >720p video routing | Preferred when cost sensitivity outweighs speed and on-resistance requirements |
| ADG1412BRUZ | Lower RDS(on) (1.3 Ω typ), higher supply voltage (up to ±15 V), TSSOP-16 only | Requires dual ±15 V rails for full performance; not drop-in for 12 V single-supply designs | Chosen for ultra-low distortion in medical imaging front-ends where power supply headroom permits |
Compared with DG442LDY-T1-E3, MAX4618ESE+ trades speed and on-resistance for lower cost in battery-powered data loggers, while ADG1412BRUZ delivers superior conductivity and linearity but demands higher supply voltages and board redesign for TSSOP layout.

FAQ
What supply voltage ranges does the DG442LDY-T1-E3 support?
The DG442LDY-T1-E3 operates from 2.7 V to 12 V on a single supply or ±3 V to ±6 V on dual supplies. At 12 V single supply, it achieves 17 Ω typical on-resistance and 20 ns turn-on time. The device maintains rail-to-rail analog signal handling across these ranges, supporting direct connection to common sensor and op-amp rails without external level shifting. DG442LDY-T1-E3 is rated for –40 °C to +85 °C operation.
How does the DG442LDY-T1-E3 differ from the DG441LDY-T1-E3 in logic behavior?
The DG442LDY-T1-E3 uses inverted control logic versus the DG441LDY-T1-E3: a logic low (≤0.8 V) on INx closes the corresponding switch, while a logic high (≥2.4 V) opens it. This complements DG441L's active-high behavior, enabling straightforward implementation of complementary switching schemes - for example, using one device for enable and the other for disable in redundant safety circuits. DG442LDY-T1-E3 shares identical pinout, RDS(on), and dynamic specs with DG441LDY-T1-E3.
Can the DG442LDY-T1-E3 handle bipolar analog signals?
Yes - when powered from dual supplies (e.g., ±5 V), the DG442LDY-T1-E3 supports analog signals from –5 V to +5 V, enabling true bipolar operation in applications like audio line-level switching or differential sensor interfaces. Internal ESD diodes clamp signals exceeding V+ or V−, so input voltages must remain within absolute maximum ratings (–0.3 V to V+ + 0.3 V). DG442LDY-T1-E3 maintains 0.25 nA leakage and flat RDS(on) across this full range.
What is the maximum signal frequency supported by the DG442LDY-T1-E3?
The DG442LDY-T1-E3 has a –3 dB bandwidth of 280 MHz under 12 V single-supply conditions, verified with 50 Ω source/load and proper PCB layout. Its off-isolation remains –50 dB at 50 MHz, and crosstalk is –95 dB at the same frequency - making it suitable for high-definition video routing (e.g., HDMI auxiliary channels) and SDSL line-card signal switching. DG442LDY-T1-E3 performance degrades at lower supplies: bandwidth drops to ~120 MHz at 3 V due to increased RDS(on).
Is the DG442LDY-T1-E3 RoHS compliant and halogen-free?
Yes - DG442LDY-T1-E3 complies with RoHS Directive 2002/95/EC and is halogen-free per IEC 61249-2-21. It contains no brominated flame retardants (BFRs), no chlorine-based flame retardants (CFRs), and total bromine and chlorine content is below 900 ppm. The device uses matte tin lead finish and green molding compound, meeting JEDEC J-STD-609A Class 1 requirements. DG442LDY-T1-E3 is manufactured in Vishay's qualified global facilities with full traceability.
