Product details
Overview
DG201BDY-E3 from Vishay Siliconix is a quad single-pole single-throw (SPST) normally closed analog switch fabricated in silicon gate CMOS technology, rated for ±22 V analog signal range, 45 Ω on-resistance, and 120 ns turn-on time, used in precision sample-and-hold circuits and digitally programmable filter designs.
For engineers reviewing the DG201BDY-E3 datasheet, DG201BDY-E3 pinout, DG201BDY-E3 application, or DG201BDY-E3 equivalent, key selection criteria include bi-directional signal handling, low 1 pC charge injection, ±22 V dual-supply operation, 20 pA leakage, and TSSOP-16 package compatibility with industrial instrumentation and test equipment layouts.
Technical Context
The DG201BDY-E3 implements four independent SPST switches with normally closed logic behavior (ON at logic low), each featuring true bi-directional conduction and rail-to-rail analog signal switching up to ±22 V. Its epitaxial layer prevents latch-up, and improved charge injection compensation minimizes transients during switching.
It supports both dual-supply (±4.5 V to ±22 V) and single-supply (4.5 V to 25 V) operation, with TTL/CMOS-compatible digital inputs (0.8 V low, 2.4 V high) and guaranteed 30 mA continuous current per channel. Off-isolation exceeds 90 dB at 100 kHz, and crosstalk remains below –95 dB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V (dual supply); enables full-range signal routing without clipping in ±15 V systems |
| On-Resistance | 45 Ω typical (RDS(on)); ensures minimal voltage drop and signal attenuation in precision analog paths |
| Charge Injection | 1 pC typical; reduces acquisition error in sample-and-hold applications to sub-mV levels |
| Turn-On Time | 120 ns typical; supports sampling rates up to ~5 MHz in fast-switching data acquisition |
| Off-Leakage Current | ±20 pA max (IS(off), ID(off)); preserves signal integrity in high-impedance sensor interfaces |
| Supply Voltage Range | ±4.5 V to ±22 V (dual); accommodates legacy ±15 V and extended-range industrial supplies |
| Logic Compatibility | TTL/CMOS (0.8 V low / 2.4 V high); interfaces directly with microcontrollers and FPGAs without level shifters |
Pinout & Package
Package: 16-pin TSSOP (JEDEC MO-153, MS-012 variant), 4.4 mm × 5.0 mm footprint, 0.65 mm pitch, 1.2 mm max height - optimized for space-constrained PCBs in portable instruments and automated test equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (IN1–IN4) | Digital control input | Active-low logic: low = ON (closed) for DG201BDY-E3; drives internal switch gate |
| 5, 6, 12, 13 (S1–S4) | Source terminal | Bi-directional analog path input/output; connects to signal source or load |
| 7, 8, 11, 14 (D1–D4) | Drain terminal | Bi-directional analog path input/output; completes switched path with corresponding Sx |
| 9 (V−) | Negative supply rail | Bias reference for negative analog swing; must be connected for dual-supply operation |
| 10 (GND) | Digital ground | Reference for logic inputs; tied to system digital ground plane |
| 15, 16 (V+) | Positive supply rail | Bias reference for positive analog swing; dual connection improves PSRR and noise immunity |
| NC (Pin 15 not used) | No connect | Pin 15 is internally unconnected; must remain floating or grounded per layout guidelines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Quad SPST NC, 35 Ω RDS(on), 100 ns tON, ±20 V rating, SOIC-16 package | Lower on-resistance but narrower supply range; no TSSOP option | Preferred when lower on-resistance is critical and SOIC-16 footprint is acceptable |
| ADG1419BRUZ | Quad SPST NC, 2.6 Ω RDS(on), 125 ns tON, ±15 V rating, TSSOP-16, higher cost | Superior on-resistance and THD, but limited to ±15 V; not suitable for ±22 V systems | Select only if ±22 V operation is unnecessary and ultra-low on-resistance justifies premium cost |
Compared with MAX4617ESE+ and ADG1419BRUZ, the DG201BDY-E3 uniquely balances ±22 V capability, 45 Ω on-resistance, and TSSOP-16 packaging-making it optimal for industrial systems requiring extended voltage range and board-space efficiency without premium pricing.

FAQ
What is the maximum analog signal voltage supported by the DG201BDY-E3?
The DG201BDY-E3 supports analog signals from V− to V+, with absolute maximum ratings of ±22 V across the V+ to V− terminals. In dual-supply operation at ±15 V, it guarantees full ±15 V analog signal range without clipping or distortion, making DG201BDY-E3 suitable for legacy industrial systems using standard ±15 V rails.
Is the DG201BDY-E3 pin-compatible with the older DG201A series?
Yes, the DG201BDY-E3 is a direct functional and pin-compatible upgrade to the DG201A, retaining identical pinout, package dimensions, and logic behavior. DG201BDY-E3 improves on-resistance (45 Ω vs. 60 Ω), leakage (20 pA vs. 100 pA), and switching speed (120 ns vs. 175 ns), while maintaining backward compatibility in existing SOIC-16 and TSSOP-16 layouts.
Does the DG201BDY-E3 require separate ground connections for analog and digital domains?
No, the DG201BDY-E3 uses a single GND pin (Pin 10) for digital logic reference and does not isolate analog and digital grounds. System-level separation must be implemented externally via PCB layout-using split ground planes and star grounding near the device-to maintain low-noise performance, especially in mixed-signal applications where DG201BDY-E3 routes sensitive analog signals.
Can the DG201BDY-E3 operate from a single +12 V supply?
Yes, the DG201BDY-E3 supports single-supply operation from +4.5 V to +25 V. At +12 V, it delivers an analog signal range of 0 V to +12 V, with RDS(on) rising to 90 Ω typical and charge injection increasing to 4 pC. This mode is validated in the datasheet and appropriate for DG201BDY-E3 use in battery-powered portable instruments where dual supplies are impractical.
What is the thermal derating behavior of the DG201BDY-E3 above 75 °C?
Above 75 °C, the DG201BDY-E3 derates power dissipation at 12 mW/°C for TSSOP-16 packages. With a maximum rated power dissipation of 640 mW at 75 °C, its usable limit drops to ~520 mW at 85 °C and ~400 mW at 95 °C. This derating ensures safe junction temperature operation and must be factored into thermal design when DG201BDY-E3 switches high-current analog signals continuously.
