Product details
Overview
DG441LDY-T1-E3 from Vishay Siliconix is a precision monolithic quad SPST low-voltage CMOS analog switch in 16-pin narrow SOIC package, featuring 20 ns turn-on time, 17 Ω on-resistance at 12 V supply, and ±3 V to ±6 V dual-supply operation. It delivers break-before-make switching for audio/video signal routing in battery-powered test equipment.
For engineers reviewing the DG441LDY-T1-E3 datasheet, DG441LDY-T1-E3 pinout, DG441LDY-T1-E3 application, or DG441LDY-T1-E3 equivalent, key selection criteria include guaranteed RDS(on) matching (≤0.5 Ω), 0.25 nA leakage at 25 °C, 2000 V ESD protection, and TTL/CMOS-compatible control logic with 0.8 V / 2.4 V thresholds.
Technical Context
The DG441LDY-T1-E3 implements four independent single-pole single-throw switches using BiCMOS fabrication, enabling simultaneous operation across 2.7–12 V single supply or ±3–±6 V dual supply. Its architecture guarantees flat on-resistance over full analog signal range and supports break-before-make timing to prevent signal shorting during channel transitions.
Control logic is inverted relative to DG442L: logic low (≤0.8 V) enables conduction, while logic high (≥2.4 V) disables all channels. Internal clamping diodes protect S/D terminals against signals exceeding V+ or V−, with forward current limited to 30 mA per terminal.
Key Specifications

|---|---|
| On-resistance (RDS(on)) | 17 Ω typical at V+ = 12 V, ensuring minimal signal attenuation in precision data acquisition paths |
| Turn-on time (tON) | 20 ns typical at 12 V, enabling high-speed multiplexing in automated test equipment |
| Leakage current | 0.25 nA max at 25 °C, preserving accuracy in high-impedance sensor interfaces |

| 5, 6, 12, 13 (S1–S4) | Source terminals | Analog input nodes; clamped to V+ or V− by internal diodes if overdriven |
| 7, 8, 11, 10 (D1–D4) | Drain terminals | Analog output nodes; support rail-to-rail signal swing within V− to V+ |
| 9 (GND) | Ground reference | Common return for digital control and substrate bias; must be low-impedance |
| 14 (V−) | Negative supply | Required for dual-supply operation; sets lower analog signal limit |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Higher RDS(on) (45 Ω typ), slower tON (40 ns), but offers 1.8 V logic compatibility | Preferred for ultra-low-voltage microcontroller interfaces where 12 V supply unavailable | Select when interfacing with 1.8 V GPIO; accept higher on-resistance for broader logic compatibility |
| ADG1412BRUZ | Lower RDS(on) (1.3 Ω typ), higher supply voltage (up to ±15 V), but larger 16-lead TSSOP package | Suitable for high-precision instrumentation requiring sub-ohm on-resistance and extended voltage range | Choose for <1 Ω RDS(on) needs; verify PCB layout supports wider TSSOP footprint |
Compared with DG441LDY-T1-E3, MAX4617ESE+ trades speed and on-resistance for 1.8 V logic support, while ADG1412BRUZ delivers superior conductivity and voltage range at the cost of larger board area and higher cost-making DG441LDY-T1-E3 optimal for balanced performance in space-constrained 3–12 V systems.

FAQ
What is the maximum analog signal voltage range supported by DG441LDY-T1-E3?
DG441LDY-T1-E3 supports analog signals from V− to V+ across its full operating range. With ±5 V dual supply, this yields ±5 V (–5 V to +5 V); with 12 V single supply, it supports 0 V to 12 V. Internal clamping diodes limit signal excursions beyond rails, but sustained overvoltage requires external current limiting per datasheet Note a.
Does DG441LDY-T1-E3 require dual supplies to operate, or can it run on single supply only?
DG441LDY-T1-E3 operates on either single supply (2.7 V to 12 V) or dual supply (±3 V to ±6 V). The DG441LDY-T1-E3 datasheet specifies performance across both configurations - e.g., RDS(on) = 17 Ω typical at 12 V single supply, and 20 Ω typical at ±5 V dual supply - with no functional limitation in either mode.
What is the guaranteed on-resistance match between channels for DG441LDY-T1-E3?
DG441LDY-T1-E3 guarantees on-resistance matching (ΔRDS(on)) of ≤0.5 Ω maximum at room temperature, measured under identical conditions (IS = 10 mA, VD = 9 V). This tight matching ensures consistent gain scaling in programmable resistor networks and minimizes channel-to-channel gain error in multi-path signal conditioning.
Can DG441LDY-T1-E3 be used in audio applications requiring low THD and wide bandwidth?
Yes, DG441LDY-T1-E3 is validated for audio routing: its 280 MHz –3 dB bandwidth, 71 dB off-isolation at 1 MHz, and flat RDS(on) (<5 Ω variation) directly support low-THD performance. Measured THD+N remains <1% at 1 kHz with 2 VPP signals, confirming suitability for line-level stereo and SDSL voice channel switching.
Is DG441LDY-T1-E3 pin-compatible with the legacy DG441 series?
Yes, DG441LDY-T1-E3 is pin-for-pin compatible with industry-standard DG441 devices, including the original DG441. The "L" suffix denotes improved performance (lower RDS(on), faster switching, enhanced ESD), but maintains identical pinout, package dimensions, and logic polarity - enabling drop-in replacement in existing SOIC-16 layouts without redesign.
