Product details
Overview
DG201BDY-T1-E3 from Vishay Siliconix is a quad single-pole single-throw (SPST) normally closed analog switch fabricated in silicon-gate CMOS technology. It supports ±22 V dual-supply operation, delivers 45 Ω typical on-resistance at ±15 V, and achieves 120 ns turn-on time with only 1 pC charge injection - enabling precision signal routing in sample-and-hold circuits and programmable filter designs.
For engineers reviewing the DG201BDY-T1-E3 datasheet, DG201BDY-T1-E3 pinout, DG201BDY-T1-E3 application, or DG201BDY-T1-E3 equivalent, key selection criteria include bi-directional analog signal handling up to ±15 V, guaranteed 30 mA continuous channel current, low 20 pA off-leakage, RoHS-compliant TSSOP-16 packaging, and compatibility with TTL/CMOS logic levels.
Technical Context
The DG201BDY-T1-E3 implements four independent SPST switches with normally closed (NC) configuration per channel, controlled by active-low digital inputs. Its epitaxial layer prevents latch-up, and internal charge injection compensation minimizes switching transients during analog signal sampling.
It operates across -40 °C to +85 °C with ±4.5 V to ±22 V dual-supply range (or +4.5 V to +25 V single-supply), supporting true bi-directional conduction when on and blocking signals beyond supply rails when off - critical for high-fidelity instrumentation front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V (full rail-to-rail handling under ±15 V supplies) |
| On-Resistance (RDS(on)) | 45 Ω typical (enables <1 LSB error in 12-bit systems with ≤1 kΩ source impedance) |
| Charge Injection | 1 pC (limits voltage glitch to <1 mV on 1 nF hold capacitor) |
| Turn-On Time (tON) | 120 ns typical (supports >1 MHz sampling in S/H applications) |
| Off-Leakage Current | ±20 pA max (preserves capacitor voltage drift <1 µV/s in 1 µF hold circuits) |
| Supply Voltage Range | ±4.5 V to ±22 V (supports wide dynamic range sensor interfaces) |
| Logic Compatibility | TTL/CMOS (0.8 V low / 2.4 V high thresholds ensure robust noise margin) |
Pinout & Package
Package: 16-pin TSSOP (JEDEC MO-153, 5.0 mm × 4.4 mm × 1.2 mm height), RoHS-compliant, lead-free termination (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (IN1–IN4) | Digital control input | Active-low logic: logic '0' (≤0.8 V) closes switch; logic '1' (≥2.4 V) opens switch |
| 5, 6, 12, 13 (S1–S4) | Source terminal | Bi-directional analog path input/output; connects to load or signal source |
| 7, 8, 11, 10 (D1–D4) | Drain terminal | Bi-directional analog path input/output; connects to destination or feedback node |
| 9 (GND) | Ground reference | Logic ground reference; must be tied to system common for proper threshold operation |
| 14 (V+) | Positive supply | Provides upper rail for analog signal swing and internal biasing |
| 15 (V−) | Negative supply | Provides lower rail for analog signal swing and internal biasing |
| 16 (NC) | No connect | Internally unconnected; must remain floating or grounded per layout guidelines |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Single-supply only (+2.7 V to +12 V); 60 Ω RDS(on); 50 pA leakage | Limited to unipolar signal paths; unsuitable for ±10 V industrial sensors | Select when cost-sensitive, low-voltage, single-supply systems dominate design constraints |
| ADG1419BRUZ | ±15 V rating; 1.3 Ω RDS(on); 100 pA leakage; 16-lead TSSOP package | Lower on-resistance but higher leakage; requires tighter layout for 16-bit performance | Choose for ultra-low distortion audio or high-resolution metrology where RDS(on) mismatch dominates error budget |
Compared with DG201BDY-T1-E3, MAX4617ESE+ lacks bipolar supply support and exhibits higher leakage, limiting use in precision DC-coupled systems; ADG1419BRUZ offers lower on-resistance but trades off leakage performance, requiring careful capacitor selection in long-hold S/H designs.

FAQ
What is the maximum analog signal voltage the DG201BDY-T1-E3 can handle?
The DG201BDY-T1-E3 supports analog signals from V− to V+, with absolute maximum ratings allowing ±22 V supply rails. Under ±15 V operation, it guarantees ±15 V analog signal range - meaning signals up to ±15 V can pass through the switch without clipping or damage, provided supply voltages are within specification. This makes DG201BDY-T1-E3 suitable for interfacing with standard industrial ±10 V sensor outputs.
Is DG201BDY-T1-E3 pin-compatible with the older DG201A series?
Yes, DG201BDY-T1-E3 maintains identical pinout and package dimensions to DG201A variants in TSSOP-16, including mechanical and electrical compatibility. The DG201B is a direct functional upgrade - offering lower on-resistance (45 Ω vs. 60 Ω), reduced leakage (20 pA vs. 100 pA), faster switching (120 ns vs. 175 ns), and enhanced latch-up immunity - with no PCB layout changes required when replacing DG201A in existing designs.
Does DG201BDY-T1-E3 support single-supply operation?
Yes, DG201BDY-T1-E3 supports single-supply operation from +4.5 V to +25 V, with guaranteed analog signal range from 0 V to V+. At +12 V supply, it delivers 90 Ω typical on-resistance and 120 ns turn-on time. Logic thresholds remain TTL/CMOS compatible (0.8 V low / 2.4 V high), and the device retains bi-directional analog conduction - making DG201BDY-T1-E3 viable for battery-powered portable instruments and mixed-signal microcontroller interfaces.
What is the thermal derating behavior of DG201BDY-T1-E3 above 75 °C?
DG201BDY-T1-E3 has a thermal derating factor of 12 mW/°C above 75 °C for its 640 mW maximum power dissipation in TSSOP-16 package. This means usable power drops linearly: at 100 °C ambient, maximum allowable dissipation is 640 mW − (25 °C × 12 mW/°C) = 340 mW. Designers must verify junction temperature using θJA = 156 °C/W and ensure sustained operation stays within −40 °C to +85 °C case temperature limits specified for the D-suffix variant.
How does the normally closed (NC) configuration of DG201BDY-T1-E3 affect system-level reliability?
The normally closed configuration of DG201BDY-T1-E3 ensures analog continuity during power loss, reset, or logic fault - critical in safety-monitoring paths and fail-safe data acquisition. When control inputs float or go high, the switch remains closed, preserving signal integrity. This behavior reduces need for external pull-downs or backup paths, simplifying design for systems where uninterrupted analog monitoring (e.g., temperature or pressure sensing) is mandatory prior to host processor initialization. DG201BDY-T1-E3 thus enhances system robustness without added components.
