Product details
Overview
DG201BDQ-T1-E3 from Vishay Siliconix is a quad single-pole single-throw (SPST) normally closed analog switch fabricated in silicon-gate CMOS, rated for ±22 V analog signal range, 45 Ω on-resistance at ±15 V supplies, and 120 ns turn-on time - used in precision sample-and-hold circuits and digitally programmable filter designs.
For engineers reviewing the DG201BDQ-T1-E3 datasheet, DG201BDQ-T1-E3 pinout, DG201BDQ-T1-E3 application, or DG201BDQ-T1-E3 equivalent, key selection criteria include guaranteed ±22 V signal handling, low 1 pC charge injection, bi-directional analog conduction, -40 °C to +85 °C operation, and TSSOP-16 packaging with validated pin mapping.
Technical Context
The DG201BDQ-T1-E3 implements four independent SPST switches with normally closed (NC) logic behavior: logic low (≤0.8 V) enables conduction; logic high (≥2.4 V) disables. Each channel features true bi-directional analog signal flow in the on state and blocks signals beyond supply rails in the off state.
Its internal epitaxial layer prevents latchup; improved charge injection compensation minimizes switching transients; and it supports both dual-supply (±4.5 V to ±22 V) and single-supply (4.5 V to 25 V) operation - enabling use in industrial instrumentation and test equipment where rail-to-rail analog integrity is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V (dual supply); 0–12 V (single supply) - supports full-range signal routing without clipping |
| On-Resistance (RDS(on)) | 45 Ω typ. at ±15 V - ensures minimal gain error and voltage drop in precision signal paths |
| Charge Injection | 1 pC typ. - limits aperture error in sample-and-hold applications to sub-mV levels |
| Turn-On Time (tON) | 120 ns max. - enables fast multiplexing in automated test equipment (ATE) systems |
| Off-Leakage Current | ±20 pA max. at ±14 V - preserves signal integrity in high-impedance sensor interfaces |
| Supply Voltage Range | ±4.5 V to ±22 V continuous - accommodates wide industrial and telecom supply architectures |
| Operating Temperature | -40 °C to +85 °C - qualified for commercial/industrial embedded environments |
Pinout & Package
Package: 16-lead TSSOP (JEDEC MO-153, MS-012 variant), 4.4 mm × 5.0 mm body, 0.65 mm pitch, lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | IN1–IN4 (digital control inputs) | TTL/CMOS-compatible logic inputs; low = ON (closed), high = OFF (open) for DG201B function |
| 5, 6, 12, 13 | S1–S4 (sources) | Analog input terminals for each SPST switch; bidirectional when ON |
| 7, 8, 11, 10 | D1–D4 (drains) | Analog output terminals; connected to Sx when INx = low; isolated otherwise |
| 9 | GND | Digital ground reference for logic interface and internal biasing |
| 14 | V− | Negative analog supply rail; must be ≤ V+ − 44 V per absolute max rating |
| 15 | V+ | Positive analog supply rail; sets upper bound of analog signal range |
| 16 | NC | No internal connection; must be left unconnected or tied to GND for mechanical stability |
Key Features
| Feature | Design Value |
|---|---|
| Normally closed topology | Ensures fail-safe signal continuity during power loss or logic fault in safety-critical monitoring paths |
| Low 1 pC charge injection | Reduces hold-mode voltage error in precision sample-and-hold circuits to <1 mV for 1 nF hold capacitors |
| ±22 V supply rating | Enables direct interfacing with ±15 V op-amp stages and industrial sensor outputs without level-shifting |

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 NO switch (opposite logic polarity); 60 Ω RDS(on); 2.7–12 V single-supply only | Requires inverted control logic; unsuitable for ±22 V or dual-supply systems | Select if only single-supply operation and normally open behavior are acceptable |

FAQ
What is the maximum analog signal voltage supported by DG201BDQ-T1-E3?
DG201BDQ-T1-E3 supports analog signals from V− to V+, with absolute maximum ratings of ±22 V across V+ and V−. Under normal operation with ±15 V supplies, it handles ±15 V analog signals. Exceeding V+ or V− clamps signals via internal diodes - forward current must remain within 30 mA per terminal to avoid damage.
Is DG201BDQ-T1-E3 compatible with TTL and CMOS logic levels?
Yes, DG201BDQ-T1-E3 is fully compatible with both TTL and CMOS logic. Its digital inputs accept VINH ≥ 2.4 V and VINL ≤ 0.8 V across the full temperature range, with input current limited to ±1 µA. This allows direct interfacing with microcontrollers, FPGAs, and standard logic families without level-shifting circuitry.
Does DG201BDQ-T1-E3 require dual supplies, or can it operate from a single supply?
DG201BDQ-T1-E3 supports both dual-supply (±4.5 V to ±22 V) and single-supply (4.5 V to 25 V) operation. In single-supply mode, V− is connected to GND and V+ supplies the positive rail. Analog signal range becomes 0 V to V+, e.g., 0–12 V at V+ = 12 V. Logic thresholds remain unchanged.
What is the thermal derating specification for DG201BDQ-T1-E3 in TSSOP package?
For the TSSOP-16 package (DQ suffix), DG201BDQ-T1-E3 has a power dissipation limit of 640 mW at ≤75 °C. Above 75 °C, power must be derated at 12 mW/°C - meaning maximum allowable power drops to 520 mW at 85 °C and 400 mW at 95 °C. This is specified in the Absolute Maximum Ratings table.
How does the normally closed (NC) functionality of DG201BDQ-T1-E3 affect system-level reliability?
The normally closed configuration of DG201BDQ-T1-E3 ensures analog continuity when power is absent or control logic is inactive - critical in safety-monitoring systems where signal path integrity must be preserved during faults. This fail-safe behavior eliminates need for external pull-up/down circuitry and reduces risk of open-circuit failure modes in industrial control loops.
