Product details
Overview
DG202DY+T from Maxim Integrated is a quad SPST normally open analog switch IC designed for bidirectional signal routing in ±4.5V to ±18V dual-supply systems. It features guaranteed break-before-make switching, 175Ω typical RDS(ON) at ±15V, <5pF OFF-capacitance per channel, and operates across –40°C to +85°C. It is used in programmable gain amplifiers and automatic test equipment where low charge injection (20pC) and rail-to-rail analog signal handling are critical.
For engineers reviewing the DG202DY+T datasheet, DG202DY+T pinout, DG202DY+T application, or DG202DY+T equivalent, this page delivers verified electrical parameters, SO-16 package mapping, real-world use scenarios, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The DG202DY+T implements four independent CMOS SPST switches with inverted logic control inputs-distinct from the DG201/DG211 family. Each switch guarantees nonlatching behavior when power supplies are disconnected while analog signals remain present, and maintains constant on-resistance over its full ±15V analog signal range.
It eliminates the need for a third logic supply (VL) required by legacy equivalents, supports TTL/CMOS-compatible inputs, and achieves <1µA input leakage and <5nA drain/source off-leakage at ±14V signal conditions-enabling high-precision, low-error signal path design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - Supports rail-to-rail signal switching without clipping in dual-supply systems. |
| RDS(ON) | 115Ω (min) to 200Ω (max) at ±15V - Ensures low insertion loss and minimal gain error in precision analog paths. |
| Off-Leakage Current | ±0.02nA typical at ±14V - Critical for maintaining accuracy in sample-and-hold and high-impedance sensor interfaces. |
| Switching Time (tON/tOFF) | 480ns / 370ns - Enables reliable operation in medium-speed multiplexing up to ~1MHz. |
| Charge Injection | 20pC - Limits voltage step error in sampling circuits, reducing hold-mode settling burden. |
| OFF-Isolation | 70dB at 100kHz - Suppresses crosstalk between adjacent channels in multi-channel data acquisition. |
| Supply Range | ±4.5V to ±18V continuous - Allows flexible system-level power architecture without external level-shifting. |
Pinout & Package
Package: 16-pin SOIC (SO), JEDEC MS-012, body width 3.9mm, lead pitch 1.27mm. RoHS-compliant, tape-and-reel packaging (DG202DY+T).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Inverted logic control inputs: Low = switch ON (normally open), compatible with TTL/CMOS levels. |
| 2, 7, 10, 15 | D1–D4 | Drain terminals - bidirectional analog I/O nodes; no polarity restriction relative to source. |
| 3, 6, 11, 14 | S1–S4 | Source terminals - paired with respective D pins; interchangeable with drains in signal flow. |
| 4 | V− | Negative supply rail - must be connected; defines lower analog signal boundary and bias reference. |
| 5 | GND | Digital ground reference - separate from analog signal return; decoupling recommended near pin. |
| 12 | N.C. | No internal connection - must be left unconnected; not usable as thermal pad or auxiliary node. |
| 13 | V+ | Positive supply rail - tied to substrate; defines upper analog signal boundary and powers internal logic. |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates third power rail dependency, simplifying PCB layout and reducing BOM count versus legacy DG212. |
| Guaranteed break-before-make | Prevents momentary short-circuit between channels during state transitions-essential for fault-tolerant multiplexing. |
| Bidirectional conduction | Enables reuse of same switch for input/output signal routing without directionality constraints or external diodes. |
| Nonlatching under signal-present power-off | Prevents destructive latch-up when analog inputs remain active during supply sequencing or brownout events. |
| Low 20pC charge injection | Minimizes voltage glitch on sampled capacitors, easing hold amplifier design and improving ADC effective resolution. |

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 |
|---|---|---|---|
| MAX4617ESE+ | Lower RDS(ON) (60Ω typ), but limited to ±5V supply; no ±15V capability. | Suitable only for low-voltage portable instrumentation-not for industrial ±12V/±15V systems. | Select MAX4617ESE+ only if supply is ≤±5V and on-resistance priority outweighs voltage range. |
| ADG1412BRUZ | Higher supply range (±16.5V), 1.8V logic compatible, but requires VLOGIC pin and has higher 35pC charge injection. | Supports mixed-voltage control (1.8V/3.3V) but adds layout complexity and degrades sample-hold fidelity. | Choose ADG1412BRUZ when interfacing to low-voltage microcontrollers and ±16.5V analog rails are acceptable. |
Compared with MAX4617ESE+ and ADG1412BRUZ, the DG202DY+T uniquely balances wide ±18V operation, no auxiliary logic supply, and ultra-low charge injection-making it optimal for industrial-grade programmable gain and precision sampling where supply flexibility and signal integrity are co-prioritized.

FAQ
What is the operating temperature range for the DG202DY+T?
The DG202DY+T is rated for –40°C to +85°C operation, matching the DG202D/E grade specification. This extended range supports deployment in industrial control cabinets, outdoor telecom infrastructure, and automotive test fixtures where ambient temperatures exceed commercial limits. The DG202DY+T maintains full parameter compliance-including RDS(ON), leakage, and switching times-across this entire span without derating.
Does the DG202DY+T require a separate logic supply voltage (VL)?
No, the DG202DY+T does not require a VL supply. Unlike the original DG212, Maxim eliminated this third rail while preserving TTL/CMOS logic compatibility. Control inputs (IN1–IN4) operate directly from the same V+ and V− supplies, simplifying power delivery and reducing board space. This is explicitly confirmed in the "Features" section and Electrical Characteristics table of the DG202 datasheet.
What is the maximum analog signal voltage the DG202DY+T can handle?
The DG202DY+T supports an analog signal range of ±15V, with absolute maximum ratings allowing up to ±18V continuous operation. Signals may swing fully between V− and V+, enabling true rail-to-rail switching without clipping. This is validated in both the Absolute Maximum Ratings and Electrical Characteristics tables, where VANALOG is specified as –15V to +15V under standard test conditions.
How does the DG202DY+T ensure break-before-make switching?
The DG202DY+T guarantees break-before-make operation through internal timing control circuitry that delays turn-on of the next switch until the previous one is fully off. This prevents momentary shorting between channels-a critical requirement in multiplexer-based signal routing. The guarantee is stated in the General Description and reinforced by measured tOFF1 (370ns) and tON (480ns) values ensuring sufficient dead time.
Can the DG202DY+T be used in bidirectional signal paths?
Yes, the DG202DY+T supports fully bidirectional analog signal flow. Its CMOS SPST architecture imposes no inherent directionality: D and S terminals are functionally interchangeable, and current flows equally well from drain to source or source to drain. This is confirmed in the General Description ("All switches conduct current in either direction") and enables flexible PCB layout in transimpedance amplifiers, H-bridge sensing, and shared-bus configurations.
