Product details
Overview
DG201ACSE+T from Maxim Integrated is a quad SPST normally closed analog switch IC designed for precision signal routing in ±4.5V to ±18V dual-supply systems. It features guaranteed break-before-make switching, 450ns max turn-off time, 600ns max turn-on time, and 115Ω typical RDS(ON) at ±15V, enabling low-distortion signal path control in test equipment and communications hardware.
For engineers reviewing the DG201ACSE+T datasheet, DG201ACSE+T pinout, DG201ACSE+T application, or DG201ACSE+T equivalent, this device supports high-voltage analog switching with latch-up immunity during supply disconnect, TTL/CMOS logic compatibility, and no VL supply requirement-critical for portable and military-grade designs requiring robust signal integrity.
Technical Context
The DG201ACSE+T implements monolithic CMOS architecture with four independent SPST switches, each controlled by dedicated logic inputs (IN1–IN4). Its internal structure ensures nonlatching behavior when power supplies are removed while analog signals remain applied.
Switching performance is defined by guaranteed timing specs: tOFF ≤ 450ns and tON ≤ 600ns under VS = 2V, RL = 1kΩ, CL = 35pF conditions. Analog signal range spans ±15V with RDS(ON) varying predictably across supply voltages-e.g., 135Ω min at ±15V and 160Ω max at ±15V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports full-rail signal switching without clipping in ±15V systems |
| RDS(ON) (max) | 200Ω - ensures minimal insertion loss and voltage drop for 1mA analog loads |
| Turn-Off Time (max) | 450ns - enables fast channel isolation critical in high-speed test sequencing |
| Turn-On Time (max) | 600ns - guarantees rapid signal path establishment for time-sensitive routing |
| Supply Range | ±4.5V to ±18V - allows operation across industrial, military, and legacy instrumentation rails |
| OFF-Isolation | 70dB - suppresses crosstalk between inactive channels in multi-channel systems |
| Charge Injection | 20pC - limits transient voltage spikes at switch output, preserving signal fidelity |
Pinout & Package
Package: 16-pin SOIC (Small Outline Integrated Circuit), body width 3.9mm, standard JEDEC MS-012 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Logic control inputs; active-high TTL/CMOS compatible; drive internal gate drivers |
| 2, 7, 10, 15 | D1–D4 | Drain terminals; carry switched analog signals toward load or downstream circuitry |
| 3, 6, 11, 14 | S1–S4 | Source terminals; connect to signal sources or upstream analog paths |
| 4 | V− | Negative supply rail input; referenced to substrate; must be connected for proper biasing |
| 5 | GND | Digital ground reference; separate from analog return but tied to system common |
| 12 | N.C. | No connection; electrically isolated; must not be soldered or routed |
| 13 | V+ | Positive supply rail input; also connected to substrate; defines upper analog rail limit |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates third power rail dependency, simplifying PCB layout and reducing BOM count vs. legacy DG211 |
| Guaranteed break-before-make | Prevents momentary short-circuit between channels during state transitions, protecting sensitive analog sources |
| Nonlatching with supplies off | Withstands input signals up to ±15V even when V+ and V− are unpowered-no destructive latch-up risk |
| CMOS/TTL logic compatible | Accepts 0.8V/2.4V logic thresholds directly from microcontrollers or FPGAs without level-shifting |
| Low power consumption | I+ ≤ 0.1mA and I− ≤ 0.1mA at full temperature range-extends battery life in portable test gear |

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-pole double-throw (SPDT), lower RDS(ON) (60Ω), but only dual-channel; requires VL supply | Not pin-compatible; lacks quad SPST topology; unsuitable for direct replacement in 4-channel routing | Select only if SPDT configuration and lower on-resistance outweigh need for fourth channel and VL elimination |
| ADG1412BRUZ | Quad SPST, ±15V rating, 1.8Ω RDS(ON), but higher supply current (1.2mA) and no guaranteed break-before-make | Superior on-resistance but higher power draw; lacks latch-up immunity during supply disconnect | Prefer for ultra-low-loss audio paths where power budget permits; avoid in portable/military systems requiring fault tolerance |
Compared with MAX4617ESE+ and ADG1412BRUZ, the DG201ACSE+T uniquely combines quad SPST topology, no-VL operation, guaranteed break-before-make, and nonlatching behavior under supply removal-making it irreplaceable in legacy-compatible, high-reliability analog routing where channel count, fault resilience, and supply simplicity are jointly critical.

FAQ
What is the maximum supply voltage range supported by the DG201ACSE+T?
The DG201ACSE+T operates continuously over ±4.5V to ±18V dual supplies. Absolute maximum ratings permit V+ to V− up to 44V, but functional operation is specified only within the ±4.5V to ±18V range. Exceeding ±18V risks parametric degradation or damage, and analog signal range remains limited to ±15V regardless of supply voltage.
Does the DG201ACSE+T require a VL logic supply voltage?
No, the DG201ACSE+T does not require a VL supply. Unlike earlier analog switches such as the DG211, Maxim eliminated the third supply rail-logic inputs (IN1–IN4) interface directly with standard TTL/CMOS levels using only V+ and V−. This reduces external component count and simplifies power domain design.
What is the guaranteed switching speed of the DG201ACSE+T?
The DG201ACSE+T guarantees a maximum turn-off time of 450ns and maximum turn-on time of 600ns under standard test conditions (VS = 2V, RL = 1kΩ, CL = 35pF). These values are production-tested and apply across the full 0°C to +70°C operating temperature range for the DG201ACSE+T variant.
How does the DG201ACSE+T prevent latch-up when power supplies are disconnected?
The DG201ACSE+T uses proprietary CMOS process design to ensure nonlatching behavior: even with V+ and V− disconnected while analog signals remain present at S/D pins, internal protection structures prevent parasitic SCR activation. This is verified per JEDEC JESD78 and guaranteed across all operating conditions.
What package type is used for the DG201ACSE+T?
The DG201ACSE+T is supplied in a 16-pin SOIC (Small Outline Integrated Circuit) package, also designated as SO or SOICN, with standard JEDEC MS-012 outline, 0.150" body width, and 1.27mm lead pitch. Pin 12 is internally unconnected (N.C.) and must remain floating.
