Product details
Overview
DG212BDY-T1-E3 from Vishay Siliconix is a quad SPST normally open analog switch IC designed for precision signal routing in instrumentation and test systems. It supports ±22 V dual-supply operation, delivers 50 Ω typical on-resistance, 1 pC charge injection, 120 ns turn-on time, and operates across –40 °C to +85 °C - enabling high-fidelity sample-and-hold and programmable filter applications.
For engineers reviewing the DG212BDY-T1-E3 datasheet, DG212BDY-T1-E3 pinout, DG212BDY-T1-E3 application, or DG212BDY-T1-E3 equivalent, key selection criteria include its bi-directional analog signal handling up to ±22 V, low leakage (±0.02 nA), RoHS-compliant TSSOP-16 package, and compatibility with TTL/CMOS logic control at VL = 5 V.
Technical Context
The DG212BDY-T1-E3 implements four independent single-pole single-throw (SPST) switches with normally open configuration, fabricated in silicon-gate CMOS to minimize latch-up risk via epitaxial isolation. Each channel supports true bi-directional signal flow when on and blocks signals beyond supply rails when off.
Its internal charge injection compensation circuitry reduces switching transients, while the dedicated VL pin enables independent logic-level translation (e.g., 5 V logic controlling ±15 V analog paths). The device requires no external components for basic operation and maintains stable rDS(on) across temperature and supply voltage variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±4.5 V to ±22 V - supports wide analog signal swing without clipping in dual-rail systems |
| On-Resistance (rDS(on)) | 45 Ω typical at ±15 V - ensures minimal signal attenuation and gain error in precision amplifiers |
| Charge Injection | 1 pC - limits voltage glitch in sample-and-hold circuits to sub-mV levels with 1 nF hold capacitor |
| Off-Leakage Current | ±0.01 nA max at ±14 V - preserves accuracy in high-impedance sensor front-ends and integrators |
| Switching Speed | tON = 120 ns, tOFF = 100 ns - enables >1 MHz multiplexing in automated test equipment |
| Logic Compatibility | TTL/CMOS with VINH ≥ 2.4 V, VINL ≤ 0.8 V - interfaces directly with microcontrollers and FPGAs without level shifters |
| Operating Temperature | –40 °C to +85 °C - qualified for industrial-grade embedded instrumentation and data acquisition |
Pinout & Package
Package: 16-pin TSSOP (JEDEC MO-153, Vishay Doc #74417), 5.00 mm × 6.40 mm footprint, 0.65 mm pitch, RoHS-compliant matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | IN1–IN4 | Digital control inputs - active-high logic turns corresponding switch ON (NO configuration) |
| 2, 6, 10, 14 | S1–S4 | Source terminals - bidirectional analog inputs/outputs; connect to signal sources or loads |
| 3, 7, 11, 15 | D1–D4 | Drain terminals - bidirectional analog inputs/outputs; paired with Sx for SPST path |
| 4 | V+ | Positive analog supply - sets upper rail for analog signal range (up to +22 V) |
| 8 | V− | Negative analog supply - sets lower rail for analog signal range (down to –22 V) |
| 12 | GND | Analog ground reference - separate from digital logic ground unless system design mandates common reference |
| 16 | VL | Logic supply voltage - decouples control logic level (e.g., 5 V) from analog supplies for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional analog signal path | Enables use as both input selector and output router in shared-bus architectures without polarity constraints |
| Epitaxial latch-up protection | Guarantees robust operation under transient overvoltage or ESD events in industrial environments |
| Dedicated VL pin | Allows independent 3.3 V or 5 V logic control while analog rails operate at ±15 V - eliminates level-shifter components |
| Low 1 pC charge injection | Reduces aperture error in sample-and-hold stages to <0.5 mV with 1 nF hold capacitor and 10 kΩ source impedance |
| ±22 V absolute max rating | Supports direct interfacing with legacy ±15 V op-amp circuits and industrial sensor outputs without external clamping |
Applications
| Industrial Data Acquisition | Automated Test Equipment |

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 (up to +36 V); no negative rail support; 60 Ω rDS(on); 2.5 pC charge injection | Not suitable for bipolar ±15 V signal paths; limited to unipolar industrial sensors and PLC I/O | Select when system uses only positive supplies and cost sensitivity outweighs bipolar performance needs |
| ADG1412BRUZ | Quad SPST NO; ±15 V rating only; 1.8 Ω rDS(on); 0.2 pC charge injection; higher ICC (120 µA) | Better precision but narrower voltage range; requires tighter layout for low-noise biasing | Prefer for ultra-low distortion audio or medical instrumentation where ±15 V suffices and leakage must be <1 pA |
Compared with DG212BDY-T1-E3, MAX4617ESE+ lacks bipolar supply capability and exhibits higher charge injection, limiting use in sample-and-hold; ADG1412BRUZ offers superior on-resistance and charge injection but sacrifices ±22 V headroom critical for legacy test equipment interfacing.

FAQ
What is the maximum analog signal voltage range supported by DG212BDY-T1-E3?
DG212BDY-T1-E3 supports analog signals from V− to V+, with absolute maximum ratings of ±22 V across V+ and V−. Under continuous operation, it handles ±4.5 V to ±22 V dual supplies, enabling full ±15 V signal routing typical in industrial instrumentation. Signals exceeding supply rails are clamped by internal diodes - forward current must remain within 30 mA per terminal.
Does DG212BDY-T1-E3 require external pull-up or pull-down resistors on its INx pins?
No, DG212BDY-T1-E3 does not require external pull-up or pull-down resistors on IN1–IN4. Its TTL/CMOS-compatible inputs have guaranteed switching thresholds (VINH ≥ 2.4 V, VINL ≤ 0.8 V) and low input current (±1 µA), allowing direct connection to microcontroller GPIOs or FPGA outputs. Internal input structure ensures stable logic state without external biasing.
Can DG212BDY-T1-E3 operate from a single +12 V supply?
Yes, DG212BDY-T1-E3 supports single-supply operation. With V+ = +12 V and V− = 0 V, it delivers 0 V to +12 V analog signal range, 90 Ω typical rDS(on), and 300 ns tON. Logic supply VL may be tied to +5 V independently. This configuration is validated in the datasheet (Document #70040, "SPECIFICATIONS for Single Supply") and used in active filter designs.
What is the thermal derating behavior of DG212BDY-T1-E3 above 75 °C?
DG212BDY-T1-E3 has a thermal derating factor of 7.6 mW/°C above 75 °C for its TSSOP package (640 mW at TA = 75 °C). At 100 °C ambient, maximum power dissipation drops to 446 mW. Derating applies to total package power - sum of I+ × V+, I− × |V−|, and IL × VL - and must account for PCB copper area and airflow in sealed enclosures.
How does the VL pin function in DG212BDY-T1-E3, and can it be tied to V+?
The VL pin sets the logic threshold reference and must be connected to the same supply as the controlling logic (e.g., +5 V for TTL). It cannot be tied to V+ if V+ exceeds 7 V - doing so risks violating the absolute maximum rating of VL relative to GND (–0.3 V to +7 V). For ±15 V analog operation with 5 V logic, VL = +5 V is mandatory; tying VL to V+ would damage the device.
