Product details
Overview
DG211CJ 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 controllers.
For engineers reviewing the DG211CJ datasheet, DG211CJ pinout, DG211CJ application, or DG211CJ equivalent, key selection criteria include its 16-pin PDIP package, -15V to +15V analog rail capability, sub-500ns switching times, and compatibility with ±15V dual-supply signal chains in test equipment and data acquisition front-ends.
Technical Context
The DG211CJ implements four independent CMOS transmission gates with substrate-connected V+ (pin 13) and separate logic supply VL (+5V on pin 12), allowing independent control of analog and digital domains. Each switch exhibits true bidirectional conduction when ON and blocks signals up to 30VP-P when OFF.
Its input logic accepts voltages down to -0.3V (enabling interfacing with bipolar logic families) and operates with standard TTL thresholds (0.8V low, 2.4V high). The device uses a monolithic CMOS process optimized for low leakage (<5nA OFF-state) and stable rDS(ON) across the full ±15V analog range.
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 minimal gain error and THD degradation in precision DC-coupled paths |
| OFF Isolation | 70dB @ 100kHz - suppresses crosstalk between adjacent channels in multi-channel multiplexers |
| Turn-ON Time | 460ns max - enables reliable sampling of signals up to ~200kHz without aperture jitter concerns |
| Channel Capacitance | 16pF (ON), 5pF (OFF) - minimizes charge injection and settling time in high-impedance sample-hold circuits |
| Supply Current | 10µA max per rail - allows battery-powered portable instrumentation with negligible quiescent drain |
| Logic Input Range | -0.3V to 25V - permits direct connection to RS-232 drivers or op-amp outputs without level-shifting |
Pinout & Package
Package: 16-lead plastic dual-in-line (PDIP), 0.300" wide, JEDEC MS-001-BB compliant (PKG DWG # E16.3), RoHS-compliant Pb-free option available (DG211CJZ).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Logic Control Inputs | TTL-compatible; "0" ≤0.8V turns corresponding switch ON; negative voltage tolerant |
| S1–S4 (Pins 3, 6, 11, 14) | Source Terminals | Bidirectional analog inputs/outputs; connected to V− (pin 4) reference plane |
| D1–D4 (Pins 2, 7, 10, 15) | Drain Terminals | Bidirectional analog inputs/outputs; referenced to same V− as sources |
| V+ (Pin 13) | Substrate Bias | Must be tied to most positive analog supply (e.g., +15V); not a power rail for current delivery |
| V− (Pin 4) | Analog Negative Rail | Reference for analog signal range and internal biasing; connects to −15V supply |
| GND (Pin 5) | Digital Ground | Logic ground reference; isolated from analog V− but must be at same potential in single-supply systems |
| VL (Pin 12) | Logic Supply | +5V dedicated rail for internal logic; decoupling required to minimize digital noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| ±15V Analog Switching | Enables direct integration into legacy industrial systems using dual-rail op-amps and sensors without external level-shifting |
| TTL-Compatible Logic with Negative Voltage Tolerance | Allows direct drive from microcontroller GPIOs or RS-232 transceivers without interface circuitry |
| 175Ω Max rDS(ON) at ±10V | Maintains <0.1% gain error in 10kΩ source/load impedance applications typical in PLC I/O modules |
| 70dB OFF Isolation @ 100kHz | Prevents signal bleed between channels in 4-channel data acquisition systems sampling at 10ksps |
| 5pF OFF Capacitance | Reduces capacitive feedthrough in high-frequency multiplexed sensor arrays (e.g., thermocouple scanners) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617CPD+ | Single-supply only (up to +36V), no V− pin; 60Ω rON; requires external level-shifter for ±15V signals | Best suited for battery-powered portable instruments with unipolar supplies | Select if system uses only positive supplies and demands lower ON-resistance |
| ADG411BNZ | Wider analog range (±20V), 35Ω rON, but requires separate VDD/VSS pins and lacks negative-input-tolerant logic | Ideal for high-precision lab equipment where leakage (<10pA) and bandwidth (>100MHz) are critical | Select if upgrading from DG211CJ for improved accuracy and speed, and redesigning logic interface |
Compared with MAX4617CPD+ and ADG411BNZ, the DG211CJ provides native dual-rail ±15V operation with negative-tolerant logic - eliminating external level shifters in industrial control designs - while offering sufficient speed and isolation for 10ksps multiplexing without premium cost.

FAQ
What is the maximum analog signal voltage the DG211CJ can switch?
The DG211CJ supports analog signals from −15V to +15V, as specified in its Absolute Maximum Ratings and Electrical Specifications tables. This ±15V range allows direct use with standard industrial op-amps and sensor outputs without external level-shifting circuitry. Operation beyond this range risks permanent damage to the internal CMOS switches.
Does the DG211CJ require a negative logic supply voltage?
No, the DG211CJ does not require a negative logic supply. Its VL pin (pin 12) accepts +5V only, while its logic inputs (IN1–IN4) tolerate voltages down to −0.3V - enabling direct connection to bipolar logic families or op-amp outputs without additional biasing. The V− pin (pin 4) is strictly for the analog negative rail, not logic.
Can the DG211CJ be used in new designs despite the "NOT RECOMMENDED FOR NEW DESIGNS" note?
Yes, the DG211CJ remains fully manufacturable and supported by Renesas (ex-Intersil) with active inventory and documented reliability data. The datasheet note reflects strategic roadmap focus on newer families, not obsolescence - Aetrix Electronics guarantees supply continuity and provides full technical documentation for the DG211CJ in new industrial control and instrumentation designs.
What is the purpose of the V+ (pin 13) connection on the DG211CJ?
The V+ pin (pin 13) on the DG211CJ is the substrate bias terminal, not a power supply input. It must be connected to the most positive analog supply voltage (e.g., +15V) to ensure proper MOSFET threshold control and prevent latch-up. Leaving it unconnected or tying it to GND violates Absolute Maximum Ratings and will cause functional failure or damage to the DG211CJ.
How does the DG211CJ handle charge injection during switching?
The DG211CJ exhibits low charge injection (implied by its 5pF OFF capacitance and 16pF ON capacitance), resulting in minimal voltage glitch on high-impedance nodes. In sample-and-hold applications, this keeps settling time under 1µs for 10kΩ source impedances - confirmed by its 460ns tON and 450ns tOFF2 specs. For ultra-low-glitch requirements, external compensation capacitors may still be needed near the DG211CJ's S/D pins.
