Product details
Overview
DG201AAK/883B from Maxim Integrated is a quad SPST normally closed analog switch optimized for high-reliability military and aerospace applications. It operates across ±4.5V to ±18V dual supplies, delivers 115Ω typical RDS(ON) at ±15V, achieves 450ns max turn-off time, and supports analog signal ranges from –15V to +15V. It is used in guidance and control systems where latch-up immunity and wide-temperature operation are critical.
For engineers reviewing the DG201AAK/883B datasheet, DG201AAK/883B pinout, DG201AAK/883B application, or DG201AAK/883B equivalent, key selection factors include guaranteed break-before-make switching, no VL supply requirement, nonlatching behavior with powered-off supplies, CMOS/TTL logic compatibility, and CERDIP packaging rated for –55°C to +125°C operation.
Technical Context
The DG201AAK/883B implements monolithic low-power CMOS architecture with four independent SPST switches, each featuring internal protection diodes clamping inputs to V+ and V–. Its logic inputs accept standard TTL/CMOS voltage levels and drive NMOS/PMOS transmission gates without external level-shifting.
Break-before-make timing is guaranteed across full temperature and supply range, preventing momentary shorting during channel switching. The device maintains analog signal integrity via low 5pF OFF-capacitance (CS(OFF), CD(OFF)) and 16pF ON-capacitance, enabling high-frequency signal routing up to 100kHz with 90dB crosstalk rejection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | –15V to +15V - supports rail-to-rail analog signals within dual-supply rails |
| RDS(ON) (max) | 175Ω at ±15V, ±10V - ensures minimal voltage drop and power loss in signal paths |
| Turn-Off Time (tOFF) | 450ns max - enables fast channel isolation for time-critical multiplexing |
| OFF-Isolation | 70dB - suppresses leakage between inactive channels in sensitive measurement circuits |
| Crosstalk (CCRR) | 90dB at 100kHz - prevents interference between adjacent switched analog signals |
| Supply Range | ±4.5V to ±18V continuous - accommodates legacy ±12V, ±15V, and modern ±5V systems |
| Operating Temp | –55°C to +125°C - qualified per MIL-PRF-38535 Class B for extended environmental robustness |
Pinout & Package
Package: 16-pin CERDIP (Ceramic Dual In-line Package), hermetically sealed, leaded, 0.300" wide body, suitable for high-reliability and space-constrained military PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Logic control inputs - active-high TTL/CMOS compatible; drive internal switch gates |
| 2, 7, 10, 15 | D1–D4 | Analog drain terminals - output side of SPST switches; connected to load or downstream circuitry |
| 3, 6, 11, 14 | S1–S4 | Analog source terminals - input side of SPST switches; accept analog signals from sources |
| 4 | V– | Negative supply rail - powers internal CMOS core and defines lower analog signal limit |
| 5 | GND | Ground reference - provides logic and substrate reference; must be low-impedance |
| 12 | N.C. | No connection - internally unconnected; must remain floating or grounded per layout guidelines |
| 13 | V+ | Positive supply rail - powers internal CMOS core and defines upper analog signal limit; tied to substrate |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates third auxiliary supply rail, simplifying power architecture and reducing BOM count |
| Nonlatching with powered-off supplies | Prevents destructive current flow when analog signals remain present during power-down sequences |
| Guaranteed break-before-make | Ensures no transient short-circuit between channels during logic transitions, critical for fault-tolerant designs |
| CMOS/TTL logic compatible | Accepts 0.8V/2.4V logic thresholds directly-no level shifters needed for microcontroller or FPGA interface |
| Monolithic low-power CMOS design | Draws only 0.1mA positive and –0.01mA negative supply current-ideal for battery-backed or thermally constrained systems |

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 |
|---|---|---|---|
| ADG201AKRZ-REEL7 | Single-supply only (±15V not supported); 180Ω RDS(ON); no MIL-spec qualification | Limited to commercial industrial systems; unsuitable for dual-supply military platforms | Select only if system uses single +15V/–15V derived from common ground and does not require MIL-PRF-38535 compliance |
| HI-508AJ | Higher RDS(ON) (300Ω typ); slower tOFF (600ns); wider 20-pin CERDIP package | Compatible with legacy MIL-STD-883 Class B boards but adds PCB area and routing complexity | Consider only when backward compatibility with HI-508A footprint and test procedures is mandatory |
Compared with ADG201AKRZ-REEL7 and HI-508AJ, DG201AAK/883B uniquely combines MIL-qualified CERDIP packaging, guaranteed ±4.5V to ±18V dual-supply operation, and sub-500ns switching-making it the only option for new designs requiring full military environmental compliance and analog signal fidelity across wide voltage rails.

FAQ
What is the maximum analog signal voltage range supported by DG201AAK/883B?
DG201AAK/883B supports an analog signal range of –15V to +15V when operated with ±15V supplies. This range scales with supply voltage: at ±10V supplies, the usable analog range is approximately –10V to +10V. The device guarantees no latch-up even if input signals exceed supply rails, thanks to internal clamping diodes and current limiting.
Does DG201AAK/883B require a third VL supply voltage like some legacy analog switches?
No, DG201AAK/883B does not require a third VL supply. Unlike earlier DG211 variants, Maxim eliminated the VL pin entirely-simplifying power design and reducing board space. All logic and analog functions operate solely from V+, V–, and GND, with TTL/CMOS-compatible inputs referenced to GND.
What is the guaranteed switching speed of DG201AAK/883B over its full temperature range?
DG201AAK/883B guarantees a maximum turn-off time of 450ns and maximum turn-on time of 600ns across its full –55°C to +125°C operating range. These values are production-tested and specified in the MIL-PRF-38535 Class B qualification report-not just typical values-ensuring consistent performance in mission-critical timing paths.
How does DG201AAK/883B prevent latch-up when power supplies are disconnected?
DG201AAK/883B incorporates process-level latch-up immunity and internal protection structures that prevent parasitic SCR activation. When V+ and V– are removed while analog signals remain applied, internal diodes clamp inputs and limit current to <25mA, ensuring the device remains nonlatching and fully recoverable upon power restoration-verified per MIL-STD-883 Method 3015.
Is DG201AAK/883B pin-compatible with other DG201A variants such as DG201ACJ or DG201AEUE?
Yes, DG201AAK/883B shares identical pinout and electrical functionality with all DG201A variants-including DG201ACJ (plastic DIP), DG201AEUE (TSSOP), and DG201ADY (SO). The only differences are temperature grade, package type (CERDIP vs. plastic/QFN/SO), and screening level (MIL-PRF-38535 Class B vs. commercial or industrial).
