Product details
Overview
DG201HSDY-T1 from Vishay Siliconix is a high-speed quad SPST CMOS analog switch designed for precision signal routing in data acquisition and sample-and-hold circuits. It delivers 38 ns turn-on time, 25 Ω on-resistance (dual-supply), 100 pA off-leakage, and TTL/CMOS logic compatibility - enabling fast, low-error switching of ±15 V analog signals in automated test equipment.
For engineers reviewing the DG201HSDY-T1 datasheet, DG201HSDY-T1 pinout, DG201HSDY-T1 application, or DG201HSDY-T1 equivalent, key selection criteria include guaranteed dual-supply operation up to ±15 V, channel-to-channel crosstalk of 100 dB at 100 kHz, 0.5 pF off-state drain-to-source capacitance, and TSSOP-16 packaging with RoHS-compliant terminations.
Technical Context
The DG201HSDY-T1 implements four independent bidirectional analog switches fabricated on a proprietary high-voltage silicon-gate process with epitaxial latchup protection. Each channel supports rail-to-rail analog signal ranges from V− to V+, with symmetrical conduction when ON and clamping diodes limiting input overvoltage beyond supply rails.
It operates from dual supplies (±15 V) or single supply (up to 16.5 V), with logic thresholds fixed at VINH ≥ 2.4 V and VINL ≤ 0.8 V. Dynamic performance is characterized with RL = 1 kΩ and CL = 35 pF, and charge injection is specified at −5 pC (dual-supply) for minimal pedestal error in integrator reset applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| tON | 38 ns typical - enables sub-26 MHz sampling in high-throughput data acquisition systems |
| rDS(on) | 25 Ω max (V+ = 15 V, V− = −15 V) - ensures <0.1% gain error in 1 kΩ load interfaces |
| IS(off) | 100 pA max at ±15.5 V - reduces DC offset drift in precision integrators and choppers |
| OIRR | 85 dB at 100 kHz - suppresses coupling between active and inactive channels in multi-channel systems |
| CDS(off) | 0.5 pF - minimizes feedthrough during fast digital transitions in communication signal paths |
| Q (Charge Injection) | −5 pC (CL = 1 nF, VS = 0 V) - limits voltage step error to <5 mV in 1 µF hold capacitors |
| Supply Range | ±15 V dual or 10.8–16.5 V single - supports legacy ±15 V instrumentation and modern single-rail designs |

| 4, 6, 12, 11 | Drain Terminals (D1–D4) | Analog inputs/outputs; electrically identical to S pins; no polarity dependency |
| 7 | V− | Negative supply rail; must be connected for dual-supply operation or grounded for single-supply mode |
| 16 | V+ | Positive supply rail; supplies internal bias and switch driver circuitry |
| 8 | GND | Analog/digital reference ground; decoupling capacitor required near pin |
| 9 | NC | No connect - internally unconnected; must remain floating or tied to GND per layout guidelines |

FAQ
What is the maximum analog signal voltage range supported by the DG201HSDY-T1?
The DG201HSDY-T1 supports analog signals from V− to V+ across all four channels. With ±15 V dual supplies, this yields a full −15 V to +15 V range. In single-supply mode (V− = GND), the range is 0 V to V+ (up to 16.5 V). Internal clamping diodes limit input excursions to (V− − 4 V) and (V+ + 4 V), protecting the device from transient overvoltage.
Does the DG201HSDY-T1 require external pull-up or pull-down resistors on its digital control inputs?
No, the DG201HSDY-T1 does not require external pull-up or pull-down resistors. Its digital inputs are TTL/CMOS compatible with defined thresholds: VINH ≥ 2.4 V for logic high and VINL ≤ 0.8 V for logic low. The input current remains within ±1 µA across temperature, allowing direct connection to microcontroller GPIO or FPGA outputs without additional biasing.
Can the DG201HSDY-T1 operate reliably in single-supply configurations?
Yes, the DG201HSDY-T1 is fully specified for single-supply operation from 10.8 V to 16.5 V with V− tied to GND. In this mode, the analog signal range is 0 V to V+, on-resistance increases to 65 Ω (typ), and turn-on time is 50 ns (typ). All timing, leakage, and isolation parameters remain guaranteed per the datasheet's single-supply specification table.
What is the thermal derating behavior of the DG201HSDY-T1 above 75 °C?
Above 75 °C, the DG201HSDY-T1's power dissipation must be linearly derated at 7.6 mW/°C for the TSSOP package. At 100 °C ambient, the allowable power drops from 600 mW (at ≤75 °C) to 409 mW. This derating ensures junction temperature remains within safe limits under continuous operation and maintains parameter stability per the datasheet's thermal characteristics.
How does the DG201HSDY-T1 handle overvoltage conditions on its analog terminals?
The DG201HSDY-T1 incorporates internal clamping diodes on all S, D, and IN pins. Signals exceeding (V− − 4 V) or (V+ + 4 V) forward-bias these diodes, diverting current to the supply rails. To avoid damage, forward diode current must be limited to the absolute maximum rating of 30 mA continuous or 100 mA pulsed (1 ms, 10% duty cycle), typically enforced via series resistors in the signal path.
