Product details
Overview
DG211CYT from Intersil is a quad SPST analog switch IC designed for bidirectional signal routing in instrumentation and process control systems. It supports ±15V analog signal switching, features 175Ω maximum ON-resistance, 70dB OFF-isolation at 100kHz, and TTL-compatible logic inputs accepting negative voltages - enabling direct interface with legacy industrial logic families.
For engineers reviewing the DG211CYT datasheet, DG211CYT pinout, DG211CYT application, or DG211CYT equivalent, key selection criteria include its 16-pin SOIC package, -15V to +15V analog rail capability, sub-500ns switching times, and guaranteed 0°C to +70°C operation - critical for precision analog multiplexing in test equipment and data acquisition front-ends.
Technical Context
The DG211CYT implements four independent CMOS transmission gates with substrate-connected V+ (Pin 13) and dual supply rails (V+ = +15V, V− = −15V), enabling true bidirectional analog conduction. Its logic interface uses VL = +5V reference and accepts input voltages down to −0.3V, supporting mixed-signal system integration without level-shifting.
Each channel exhibits matched ON-capacitance (16pF), low OFF-capacitance (5pF per terminal), and <5nA leakage at ±14V off-state - ensuring minimal crosstalk (−90dB) and high signal integrity in multi-channel sampling architectures where channel-to-channel isolation is essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports full-range bipolar signal switching without clipping in industrial sensor interfaces. |
| rDS(ON) Max | 175Ω - ensures ≤0.1% gain error in 10kΩ impedance paths at mid-scale analog signals. |
| OFF Isolation | 70dB at 100kHz - suppresses coupling between active and inactive channels in multiplexed ADC drivers. |
| Turn-ON Time | 460ns typical - enables ≤1MHz channel scan rates in time-division multiplexed systems. |
| Channel Crosstalk | −90dB - prevents measurable interference between adjacent switched signals in precision measurement circuits. |
| Supply Current | ≤10µA per rail - allows battery-powered portable instrumentation with negligible quiescent drain. |
| Logic Input Range | Accepts −0.3V to +25V - eliminates need for external clamping diodes when interfacing with open-collector or negative-biased logic. |
Pinout & Package
Package: 16-lead SOIC (M16.15), 3.9mm × 9.8mm body, 1.27mm pitch, RoHS-compliant matte tin termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Logic Control Inputs | TTL/CMOS-compatible digital inputs; low = ON (≤0.8V), high = OFF (≥2.4V). |
| S1–S4 (Pins 3, 6, 11, 14) | Source Terminals | Analog input nodes; bidirectional - function as either input or output depending on signal flow direction. |
| D1–D4 (Pins 2, 7, 10, 15) | Drain Terminals | Analog output nodes; electrically identical to sources - no intrinsic directionality in ON state. |
| V+ (Pin 13) | Positive Supply / Substrate Tie | +15V analog rail and substrate connection; must be tied to most positive potential in circuit. |
| V− (Pin 4) | Negative Supply | −15V analog rail; establishes lower bound of switchable signal range and bias for internal transistors. |
| GND (Pin 5) | Digital Ground Reference | Reference for logic inputs and VL supply; isolated from analog grounds to minimize noise coupling. |
| VL (Pin 12) | Logic Supply Voltage | +5V reference for input threshold definition; decoupling capacitor required for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| ±15V Analog Switching | Enables direct connection to industrial sensors and actuators operating across full bipolar voltage ranges. |
| TTL-Compatible Logic Inputs | Accepts standard 0V/5V logic while tolerating −0.3V undershoot - simplifies interface with microcontrollers and FPGAs. |
| Low ON-Resistance Match | 150Ω typical rDS(ON) with tight unit-to-unit matching - preserves amplitude accuracy in multi-channel calibration systems. |
| High OFF-Isolation | 70dB attenuation at 100kHz - maintains signal fidelity during channel scanning in 16-bit data acquisition applications. |
| Pb-Free SOIC Packaging | RoHS-compliant M16.15 package with matte tin e3 finish - compatible with both SnPb and Pb-free reflow profiles. |

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 operation (up to +36V), 60Ω rDS(ON), but only dual-channel and no negative rail support. | Limited to unipolar signal paths; unsuitable for ±15V instrumentation requiring true bipolar switching. | Select only for single-rail, high-speed (<100ns) applications where negative voltage handling is unnecessary. |
| ADG1414BRUZ | Quad SPST, ±15V rating, 1.8Ω rDS(ON), but requires separate logic supply and has higher 1.2µA IIL. | Better performance in low-distortion audio routing, but over-spec'd and cost-prohibitive for industrial DAQ. | Prefer for high-fidelity signal chains where ON-resistance and THD matter more than cost and logic simplicity. |
Compared with MAX4617ESE+ and ADG1414BRUZ, the DG211CYT delivers optimal balance of bipolar rail support, TTL compatibility, and SOIC packaging for cost-sensitive industrial analog multiplexing - without requiring external level shifters or complex bias networks.

FAQ
What is the maximum analog signal voltage the DG211CYT can switch?
The DG211CYT supports analog signals from −15V to +15V relative to ground when operated with V+ = +15V and V− = −15V. This ±15V range is specified in the Absolute Maximum Ratings and Electrical Specifications tables of the FN3118 datasheet, and applies to all four channels of the DG211CYT under normal operating conditions.
Does the DG211CYT require external pull-up resistors on its logic inputs?
No, the DG211CYT does not require external pull-up resistors. Its logic inputs are TTL-compatible and accept voltages from −0.3V to +25V, with defined thresholds of ≤0.8V for logic low and ≥2.4V for logic high. The device draws only ±0.0004µA typical input current at valid logic levels, making it compatible with open-drain or microcontroller GPIO outputs without additional biasing components.
Can the DG211CYT be used with a single +12V supply instead of dual ±15V rails?
No - the DG211CYT requires dual supplies: V+ must be at least +12V and V− must be at least −12V to guarantee full ±15V analog signal switching and meet datasheet specifications. Using only a +12V supply (with V− tied to GND) violates the Absolute Maximum Rating for VS or VD to V− and risks latch-up or permanent damage, as confirmed by the FN3118 Rev 5.00 datasheet.
What is the thermal resistance (θJA) of the DG211CYT in its SOIC package?
The DG211CYT in the 16-lead SOIC package (M16.15) has a typical junction-to-ambient thermal resistance (θJA) of 120°C/W, as specified in the Thermal Information section of the FN3118 datasheet. This value assumes mounting on an evaluation PCB in free air and is used to calculate junction temperature rise under load for reliability analysis of the DG211CYT.
Is the DG211CYT pin-compatible with other variants like DG211CJ or DG211CVZ?
Yes - the DG211CYT shares identical pinout and electrical functionality with DG211CJ (PDIP) and DG211CVZ (TSSOP), as confirmed by the common "DG211" functional block diagram, truth table, and metallization mask layout across all packages in the FN3118 datasheet. All variants use the same 16-pin assignment and switching characteristics, differing only in package type and RoHS compliance status.
