Product details
Overview
DG201BDY from Vishay Siliconix is a quad single-pole single-throw (SPST) analog switch with normally closed (NC) configuration, fabricated in silicon-gate CMOS technology. It supports ±22 V dual-supply operation or +25 V single-supply operation, delivers 45 Ω typical on-resistance at ±15 V, 120 ns turn-on time, and 1 pC charge injection - enabling precision signal routing in instrumentation and test equipment.
For engineers reviewing the DG201BDY datasheet, DG201BDY pinout, DG201BDY application, or DG201BDY equivalent, key selection criteria include its bi-directional analog signal handling up to ±15 V, low leakage (±20 pA), RoHS-compliant TSSOP-16 package, and compatibility with TTL/CMOS logic levels.
Technical Context
The DG201BDY implements four independent NC analog switches with true bi-directional conduction when on and rail-to-rail blocking when off. Its epitaxial layer prevents latchup, and improved charge injection compensation minimizes switching transients in sample-and-hold circuits.
It operates across –40 °C to +85 °C, supports continuous analog signals from –15 V to +15 V under dual supply (V+ = +15 V, V– = –15 V), and maintains <100 Ω max RDS(on) over full temperature range - critical for low-distortion multiplexing in industrial data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±4.5 V to ±22 V dual supply; +4.5 V to +25 V single supply - enables wide dynamic range signal conditioning |
| RDS(on) | 45 Ω typ. at ±15 V - ensures minimal insertion loss and gain error in precision amplifier paths |
| Charge Injection | 1 pC typ. - reduces aperture error in sample-and-hold applications below 5 mV offset |
| tON/tOFF | 120 ns / 65 ns typ. - supports >1 MHz switching in automated test equipment |
| IS(off)/ID(off) | ±20 pA max. at ±14 V - preserves high-impedance node integrity in sensor front-ends |
| Off Isolation | 90 dB at 100 kHz - suppresses crosstalk between channels in multi-channel DAQ systems |
| Package | TSSOP-16 (JEDEC MO-153) - 5.0 mm × 6.4 mm footprint with 0.65 mm pitch for space-constrained PCBs |
Pinout & Package
DG201BDY is housed in a 16-pin thin shrink small-outline package (TSSOP) per JEDEC MO-153, with 0.65 mm lead pitch, 5.0 mm width, and 6.4 mm length. Pin 1 is marked by a dot or beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (IN1–IN4) | Digital control inputs | Active-low logic: logic "0" ≤ 0.8 V closes switch; logic "1" ≥ 2.4 V opens switch |
| 5, 6, 10, 11 (S1–S4) | Source terminals | Bi-directional analog input/output nodes; connected to load or signal source |
| 7, 8, 14, 15 (D1–D4) | Drain terminals | Bi-directional analog input/output nodes; connected to common bus or ADC input |
| 9 (GND) | Ground reference | Logic ground reference; must be tied to system digital ground |
| 12 (V–) | Negative supply rail | Bias for analog channel; sets lower bound of signal range (e.g., –15 V) |
| 13 (V+) | Positive supply rail | Bias for analog channel; sets upper bound of signal range (e.g., +15 V) |
| 16 (NC) | No connect | Internally unconnected; must remain floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Normally closed (NC) topology | Ensures fail-safe signal path continuity during power loss or logic fault in safety-critical monitoring |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | Quad SPST, NC; 1.8 Ω RDS(on); ±15 V supply; 20 ns tON; LFCSP-16 package | Higher speed and lower on-resistance, but requires tighter layout control due to 3 mm × 3 mm CSP footprint | Select for high-speed (<10 MSPS) data acquisition where 1.8 Ω RDS(on) justifies cost and layout complexity |
| MAX4617ESE+ | Quad SPST, NC; 60 Ω RDS(on); ±20 V supply; 150 ns tON; SOIC-16 package | SOIC-16 footprint matches legacy layouts; slightly higher RDS(on) and slower switching than DG201BDY | Select when drop-in replacement in existing SOIC-based designs is required and 60 Ω on-resistance is acceptable |

FAQ
What is the maximum analog signal voltage the DG201BDY can switch?
The DG201BDY supports analog signals from –15 V to +15 V when operated with ±15 V supplies, and up to ±22 V supply rails. Signals exceeding V+ or V– are clamped by internal diodes; forward current must be limited to rated values to avoid damage. This capability allows direct interfacing with industrial ±10 V sensor standards without external protection circuitry in the DG201BDY design.
Is DG201BDY pin-compatible with the older DG201A series?
Yes, DG201BDY is pin-compatible with DG201A variants in the same package type (e.g., SOIC-16 or TSSOP-16), sharing identical pinout, logic polarity, and functional block diagram. However, DG201BDY delivers improved specifications: 45 Ω vs. 60 Ω typical RDS(on), 1 pC vs. 5 pC charge injection, and enhanced leakage performance - all verified in the DG201BDY datasheet revision J.
Can DG201BDY operate from a single +12 V supply?
Yes, DG201BDY supports single-supply operation from +4.5 V to +25 V. At +12 V, it guarantees analog signal range from 0 V to 12 V, RDS(on) ≤ 200 Ω, and tON ≤ 300 ns. The device maintains TTL/CMOS-compatible logic thresholds (VINH ≥ 2.4 V, VINL ≤ 0.8 V) regardless of supply configuration - confirmed in DG201BDY specification tables for single-supply conditions.
What is the thermal derating behavior of DG201BDY above 75 °C?
For DG201BDY in TSSOP-16 package, power dissipation must be derated at 12 mW/°C above 75 °C. With a maximum rated power of 640 mW at 75 °C, this yields 520 mW at 85 °C and 400 mW at 95 °C. These derating values are explicitly specified in the Absolute Maximum Ratings table of the DG201BDY datasheet and apply to all operating conditions.
Does DG201BDY require external pull-up or pull-down resistors on its digital inputs?
No, DG201BDY digital inputs are TTL/CMOS compatible with guaranteed VINH ≥ 2.4 V and VINL ≤ 0.8 V, and input current ≤ ±1 µA across temperature. The DG201BDY datasheet confirms no external biasing is needed when driven directly from standard logic outputs - simplifying interface design and reducing BOM count in systems using microcontrollers or FPGAs.
