Product details
Overview
DG201ADY+T from Maxim Integrated is a quad SPST normally closed analog switch IC designed for high-voltage bipolar signal routing in precision instrumentation and test systems. It operates across ±4.5V to ±18V supplies, delivers 115Ω typical RDS(ON) at ±15V, achieves 450ns max turn-off time, and supports analog signal ranges up to ±15V - enabling use in military radios and guidance control interfaces where rail-to-rail switching integrity is critical.
For engineers reviewing the DG201ADY+T datasheet, DG201ADY+T pinout, DG201ADY+T application, or DG201ADY+T equivalent, key selection criteria include guaranteed break-before-make timing, no VL supply requirement, nonlatching behavior under powered-down signal conditions, and SO-16 package compatibility with legacy DIP/SO footprints in high-reliability analog signal paths.
Technical Context
The DG201ADY+T implements four independent CMOS SPST switches with monolithic low-power design and TTL/CMOS logic-compatible inputs. Its internal architecture eliminates the third VL supply required by earlier-generation equivalents, simplifying power domain management in dual-supply systems.
Each switch guarantees break-before-make operation and maintains nonlatching behavior even when V+ and V− are disconnected while analog signals remain present on S/D terminals. Switching performance is characterized over full temperature range (−40°C to +85°C) with specified tON ≤ 600ns and tOFF ≤ 450ns at ±15V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports full-rail analog signal switching without clipping in ±15V op-amp and DAC/ADC interface circuits |
| RDS(ON) | 115Ω (typ), 175Ω (max) at ±10V - ensures minimal insertion loss and distortion in audio, sensor, and precision measurement paths |
| Turn-Off Time | 450ns (max) - enables fast channel isolation in automated test equipment and real-time signal routing applications |
| Supply Range | ±4.5V to ±18V continuous - allows flexible integration into industrial, military, and telecom power architectures |
| OFF-Leakage Current | ±5nA (max) at ±14V - preserves signal integrity in high-impedance sensor front-ends and sample-hold circuits |
| Channel Capacitance | 16pF (CD+S(ON)) - minimizes feedthrough and crosstalk in multi-channel multiplexed systems |
| OFF-Isolation | 70dB - provides robust channel-to-channel rejection in sensitive RF and communication signal paths |
Pinout & Package
Package: 16-pin SOIC (Small Outline Integrated Circuit), JEDEC MS-012, body width 3.9mm, lead pitch 1.27mm, RoHS-compliant, tape-and-reel packaging (DG201ADY+T).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Logic control inputs - active-high TTL/CMOS compatible; drive internal gate to close respective SPST switch |
| 2, 7, 10, 15 | D1–D4 | Analog switch drain terminals - connect to signal source side; rated for ±15V analog swing |
| 3, 6, 11, 14 | S1–S4 | Analog switch source terminals - connect to load/output side; symmetric with D pins for bidirectional routing |
| 4 | V− | Negative supply input - must be connected to system −VEE; substrate tie for CMOS switch core |
| 5 | GND | Digital ground reference - separate from analog return; decoupling required near pin for noise immunity |
| 12 | N.C. | No connection - internally unconnected; must remain floating per datasheet |
| 13 | V+ | Positive supply input - connected to substrate; requires local ±15V bypass capacitor |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates third power rail dependency, reducing BOM count and PCB layout complexity vs. legacy DG211 |
| Guaranteed break-before-make | Prevents momentary short-circuit between channels during switching - critical for fault-tolerant multiplexer designs |
| Nonlatching under powered-down conditions | Remains electrically stable when V+/V− are off but analog signals persist on S/D pins - essential for hot-swap safety |
| ±4.5V to ±18V operation | Supports wide-range bipolar supplies without external level-shifting - simplifies integration in mixed-signal test racks |
| Low 115Ω RDS(ON) | Minimizes gain error and THD in precision analog paths; stable across ±15V supply and full temperature range |
Applications
| Winchester Disk Drive Control | Automated Test Equipment (ATE) |

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+ | Single-supply only (up to +36V), no negative rail support; 400ns tOFF, higher RDS(ON) (200Ω typ) | Not suitable for bipolar ±15V signal routing; limited to unipolar industrial sensor interfaces | Select only if system uses single positive supply and does not require true rail-to-rail analog swing |
| ADG1412BRUZ | ±15V rated, 1.8Ω RDS(ON), but requires VL bias and lacks guaranteed break-before-make | Higher performance in ON-resistance but introduces additional supply dependency and timing uncertainty | Choose when ultra-low RDS(ON) dominates over supply simplicity and deterministic switching sequence |
Compared with MAX4617ESE+ and ADG1412BRUZ, the DG201ADY+T uniquely combines bipolar ±18V operation, no-VL architecture, guaranteed break-before-make, and −40°C to +85°C qualification - making it the only option among the three qualified for military radio and guidance control signal routing without design compromises.

FAQ
What is the operating temperature range for DG201ADY+T?
The DG201ADY+T is rated for −40°C to +85°C operation, matching the DG201ADx grade specification. This extended temperature range enables deployment in military radios, avionics guidance units, and industrial test racks exposed to wide ambient variations. The device maintains full electrical compliance-including RDS(ON), leakage, and switching times-across this entire range without derating.
Does DG201ADY+T require a VL supply voltage?
No, DG201ADY+T does not require a VL supply. Unlike the original DG211 and many competing analog switches, the DG201ADY+T integrates internal level-shifting circuitry that eliminates the need for a third logic supply rail. This simplifies power design, reduces component count, and improves system reliability-particularly in portable and battery-powered test equipment where supply rails are constrained.
What is the maximum analog signal voltage supported by DG201ADY+T?
The DG201ADY+T supports analog signals from −15V to +15V, as defined by its ±15V analog signal range specification. This rail-to-rail capability is guaranteed under ±15V supply conditions and remains functional across the full ±4.5V to ±18V supply range. Signals exceeding these limits may forward-bias internal protection diodes and must be clamped externally per datasheet Figure 2 recommendations.
How does DG201ADY+T ensure safe operation when power supplies are removed?
DG201ADY+T guarantees nonlatching behavior when V+ and V− are disconnected while analog signals remain present on S or D terminals. Internal design prevents parasitic SCR activation, allowing the device to remain in a high-impedance, non-conductive state without destructive current flow. This feature is explicitly validated in Maxim's absolute maximum ratings and electrical characteristics tables for the DG201A family.
Is DG201ADY+T pin-compatible with DG211DY?
No, DG201ADY+T is not pin-compatible with DG211DY. Although both are 16-pin SOIC quad SPST switches, their pin functions differ: DG211DY assigns Pin 12 to GND, whereas DG201ADY+T designates Pin 12 as N.C. (no connection). Additionally, logic input assignments and supply pin placements vary between the two families. Direct replacement requires PCB layout revision and validation of timing and leakage behavior.
