Product details
Overview
DG612DY-T1 from Vishay Siliconix is a high-speed, low-glitch quad SPST analog switch IC designed for precision signal routing in fast-switching systems. It features 12 ns turn-on time, 18 Ω on-resistance, ±2 pC charge injection, 500 MHz bandwidth, and operates from ±3 V to ±10.5 V dual supplies or 5–21 V single supply. It is used in pixel-rate video switching and DAC deglitching where minimal transient error and wide analog bandwidth are critical.
For engineers reviewing the DG612DY-T1 datasheet, DG612DY-T1 pinout, DG612DY-T1 application, or DG612DY-T1 equivalent, key selection criteria include guaranteed 12 ns tON at 3 pF load, logic-level compatibility (VIH ≥ 4 V, VIL ≤ 1 V), low RDS(on) matching (ΔRDS(on) ≤ 2 Ω), -40 °C to +85 °C operation, and SOIC-16 package thermal derating (7.6 mW/°C above 75 °C).
Technical Context
The DG612DY-T1 implements four independent SPST switches using Vishay's proprietary D/CMOS process-n-channel DMOS FETs for low RDS(on) and fast switching, paired with low-power CMOS control logic and level translators. Each channel conducts bidirectionally when on and blocks up to 16 Vp-p when off.
Its architecture minimizes parasitic capacitance (CS(on) = 10 pF, CD(off) = 2 pF) and charge injection (Q = 4 pC typ., ΔQ = 3 pC max.) to reduce glitch energy and aperture uncertainty in sample-and-hold and synchronous demodulator circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| tON | 12 ns typical - enables sub-83 MHz switching without timing violation in 3 pF load systems |
| RDS(on) | 18 Ω typical - ensures <0.1 dB insertion loss at 50 Ω system impedance |
| Charge injection | ±2 pC max. - limits step error to <1 LSB in 12-bit 1 nF hold capacitor applications |
| Bandwidth | 500 MHz - supports full-swing NTSC/PAL video and multi-MSPS ADC/DAC interfaces |
| VANALOG range | -5 V to +7 V (V+ = 12 V, V− = −5 V) - accommodates bipolar video and industrial sensor signals |
| Logic thresholds | VIH ≥ 4 V, VIL ≤ 1 V - ensures robust interfacing with 5 V CMOS microcontrollers and FPGAs |
| Off isolation | 74 dB at 5 MHz - suppresses crosstalk between adjacent video or RF channels |
Pinout & Package
Package: 16-pin narrow SOIC (JEDEC MS-012), body dimensions 9.9 mm × 3.9 mm × 1.5 mm, lead pitch 1.27 mm, RoHS-compliant (Pb-free terminations).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 7, 8, 11, 12 (D1–D4) | Drain terminals | Analog output nodes; connect to load, ADC input, or downstream stage |
| 9 (V−) | Negative supply rail | Bias for NMOS switch FETs; supports dual-supply operation down to −10 V |
| 10 (V+) | Positive supply rail | Bias for PMOS switch FETs; supports up to +21 V single-supply operation |
| 15 (GND) | Ground reference | Logic ground and substrate reference; must be tied to system 0 V |
| 16 (VL) | Logic supply voltage | Separate 4–V+ rail for CMOS control logic; isolates digital noise from analog paths |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612ESE+ | Higher RDS(on) (35 Ω typ.), slower tON (25 ns), no separate VL pin | Less suitable for <100 ns glitch-critical DAC deglitching; requires shared VCC for logic/analog | Choose when cost sensitivity outweighs speed and isolation requirements |
| ADG1412BRUZ | Lower RDS(on) (1.3 Ω), higher supply voltage limit (+33 V), but larger 16-lead TSSOP package | Better for high-voltage industrial I/O; less optimal for space-constrained video PCBs due to 5 mm × 4.4 mm footprint | Choose when ultra-low on-resistance and extended voltage range are mandatory |
Compared with MAX4612ESE+ and ADG1412BRUZ, the DG612DY-T1 delivers the best balance of speed (12 ns), low charge injection (±2 pC), and compact SOIC-16 packaging for video and high-speed data acquisition-without requiring layout changes or voltage rail redesign.

FAQ
What is the maximum analog signal voltage range supported by the DG612DY-T1?
The DG612DY-T1 supports an analog signal range of V− to (V+ − 5 V) under recommended operating conditions. With V+ = 15 V and V− = −3 V, the usable range is −3 V to +10 V. Absolute maximum ratings allow signals from (V− − 0.3 V) to (V+ + 16 V), but sustained operation beyond the recommended range risks increased leakage and distortion. The DG612DY-T1 datasheet specifies VANALOG = −5 V to +7 V at V+ = 12 V, V− = −5 V.
Does the DG612DY-T1 require separate logic and analog supplies?
Yes-the DG612DY-T1 has a dedicated VL pin (Pin 16) for logic supply, independent from V+ and V−. VL must be between 4 V and V+, enabling noise isolation between digital control circuitry and sensitive analog signal paths. This separation reduces digital switching noise coupling into analog channels, a key design advantage over single-rail switches. The DG612DY-T1 achieves this while maintaining full 5 V CMOS logic compatibility.
How does the DG612DY-T1 differ from the DG611DY-T1 in functionality?
The DG612DY-T1 and DG611DY-T1 are functionally identical quad SPST analog switches but with opposite logic polarity: DG612DY-T1 turns switches ON when INx = HIGH (≥4 V), whereas DG611DY-T1 turns them ON when INx = LOW (≤1 V). Both share identical electrical specs-12 ns tON, 18 Ω RDS(on), ±2 pC charge injection-and pinout. The DG612DY-T1 is selected when active-high control aligns with system FPGA or MCU GPIO drive capability.
Can the DG612DY-T1 operate from a single 5 V supply?
No-the DG612DY-T1 requires at minimum two supplies: V+ and V− (dual supply) or V+ and GND with VL referenced to V+ (unipolar). Its internal DMOS architecture needs both positive and negative gate drive voltages to fully enhance complementary FETs. A single 5 V rail cannot bias the NMOS and PMOS switch elements simultaneously. The DG612DY-T1 datasheet specifies unipolar operation only with V+ = 5–21 V, V− = GND, and VL = 4–V+.
What is the thermal derating behavior of the DG612DY-T1 in SOIC-16 package?
The DG612DY-T1 in narrow SOIC-16 package has a power dissipation rating of 600 mW at ≤75 °C ambient. Above 75 °C, it must be derated at 7.6 mW/°C per the datasheet. At 105 °C ambient, maximum allowable power drops to 372 mW. This derating ensures junction temperature remains within safe limits (TJ ≤ 150 °C) under continuous operation. The DG612DY-T1 thermal performance is validated per JEDEC JESD51 standards and applies regardless of supply configuration.
