Product details
Overview
DG401AK/883B from Maxim Integrated is a dual, high-speed, single-pole/single-throw (SPST) analog switch designed for precision signal routing in military and aerospace systems. It features guaranteed 20Ω typical on-resistance, ≤2Ω channel-to-channel rDS(ON) matching, ≤3Ω on-resistance flatness over ±15V signal range, and ≤15pC charge injection. It operates from bipolar supplies of ±4.5V to ±20V and supports rail-to-rail analog signal switching in guidance and control systems.
For engineers reviewing the DG401AK/883B datasheet, DG401AK/883B pinout, DG401AK/883B application, or DG401AK/883B equivalent, this page delivers verified electrical parameters, MIL-STD-883B qualified package details, truth-table–confirmed logic behavior, and real-world timing performance (tON ≤ 150ns, tOFF ≤ 100ns) under extended temperature conditions.
Technical Context
The DG401AK/883B implements two independent SPST switches with TTL/CMOS-compatible digital inputs (IN1, IN2), each controlling conduction between one source (S1/S2) and drain (D1/D2) terminal. Its silicon-gate 44V process ensures robust operation across –40°C to +85°C with guaranteed leakage <5nA at +85°C and rail-to-rail analog handling from V– to V+.
Switching is noninverting: logic high at INx closes the corresponding Sx–Dx path. The device requires separate logic supply (VL = +5V) and substrate-connected V+, and all unused pins (N.C.) are unconnected internally - critical for layout integrity in high-reliability PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (rDS(ON)) | 20Ω typ (ensures minimal signal attenuation and gain error in precision instrumentation paths) |
| rDS(ON) match | ≤2Ω max (enables matched gain/phase response in differential or dual-channel sampling) |
| On-resistance flatness | ≤3Ω max over ±10V (maintains consistent channel linearity across full analog swing) |
| Charge injection | ≤15pC (limits voltage glitch on sample-hold capacitors, preserving ADC accuracy) |
| Off-leakage current | <5nA at +85°C (prevents signal drift in high-impedance sensor interfaces) |
| Switching time (tON/tOFF) | 150ns / 100ns max (supports >5MHz multiplexed signal acquisition without timing skew) |
| Analog signal range | ±15V (rail-to-rail operation with ±15V supplies enables direct interfacing with op-amp outputs) |
Pinout & Package
Package: 16-pin CERDIP (ceramic dual in-line package), hermetically sealed, MIL-STD-883B qualified, lead finish: solder-dipped, RoHS-compliant per MIL-PRF-19500.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | D1, D2 (Drain) | Analog output terminals; bidirectional signal path when switch is ON; must remain within V– to V+ |
| 2, 10 | S1, S2 (Source) | Analog input terminals; connected to signal source; referenced to same ground as V–/V+ |
| 9, 16 | IN1, IN2 | TTL/CMOS logic inputs; active-high control; require VL = +5V for guaranteed switching threshold |
| 11 | V+ | Positive supply input (–4.5V to +30V range); also substrate connection - must be tied before V– |
| 12 | VL | Logic supply input; fixed +5V required for TTL compatibility; not tied to V+ |
| 13 | GND | Analog/digital reference ground; common return for V–, VL, and logic inputs |
| 14 | V– | Negative supply input (–30V to +4.5V range); power sequencing: V+ → VL → V– → inputs |
| 2–7, 15 | N.C. | No internal connection; must be left floating or grounded per board-level EMI requirements |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed rDS(ON) matching | ≤2Ω max between S1–D1 and S2–D2 channels - essential for balanced differential signal paths |
| Rail-to-rail analog capability | Full V– to V+ signal handling with ±15V supplies - eliminates level-shifting in wide-dynamic-range systems |
| Low charge injection | ≤15pC - reduces hold-mode error in sample-and-hold circuits using ≥1nF capacitors |
| MIL-STD-883B qualification | Tested per Method 5005 (steady-state life), 5007 (thermal cycling), and 5011 (hermeticity) - certified for flight-critical use |
| Bipolar/single-supply flexibility | Operates from ±4.5V to ±20V or +10V to +30V - simplifies power architecture in mixed-signal avionics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG401TQ (Analog Devices) | Higher rDS(ON) (45Ω max), no MIL-STD-883B option, 16-lead CQCC package | Lacks radiation-hardened screening; suitable for commercial industrial but not flight hardware | Select ADG401TQ only if MIL qualification is unnecessary and higher on-resistance is acceptable. |
| HI-506AJ (Honeywell) | Slower switching (tON = 350ns), wider temp range (–55°C to +125°C), same CERDIP-16 | Validated for space-grade TID tolerance; used where total ionizing dose >100krad required | Choose HI-506AJ when radiation hardness outweighs speed requirements in satellite payloads. |
Compared with ADG401TQ and HI-506AJ, DG401AK/883B uniquely balances MIL-qualified reliability, 150ns speed, and ≤2Ω matching - making it optimal for high-fidelity, thermally stressed guidance electronics where parameter consistency is non-negotiable.

FAQ
What is the maximum allowable voltage difference between V+ and V– for DG401AK/883B?
The DG401AK/883B has an absolute maximum rating of 44V between V+ and V–. This limit is strictly enforced to prevent junction breakdown in its 44V silicon-gate process. Operation at ±20V (40V total) is fully specified and recommended for long-term reliability; exceeding 44V risks permanent damage even for transient events.
Does DG401AK/883B require external blocking diodes for overvoltage protection?
No - DG401AK/883B includes internal clamping diodes on all analog terminals (S, D, IN). However, external series diodes are recommended only if strict power-supply sequencing cannot be guaranteed (V+ first, then VL, then V–). Adding diodes reduces analog range by ~1V but preserves DG401AK/883B's low rDS(ON) and leakage specs.
Can DG401AK/883B operate with VL tied directly to V+?
No - VL must be regulated at +5V for guaranteed TTL compatibility. If VL connects to V+, logic thresholds shift and may cause incomplete turn-on or increased static current. The DG401AK/883B datasheet explicitly requires VL = +5V regardless of V+ magnitude; a dedicated +5V regulator or LDO is necessary in all designs.
What is the guaranteed off-isolation performance of DG401AK/883B at 1MHz?
DG401AK/883B guarantees 72dB off-isolation at 1MHz (RL = 100Ω, CL = 5pF), measured as 20log(VS/VD). This value ensures minimal signal bleed-through in high-gain receiver chains, such as those found in military radios where adjacent-channel rejection is critical to avoid desensitization during simultaneous TX/RX operation.
How does the DG401AK/883B handle analog signals beyond the supply rails?
DG401AK/883B clamps analog signals exceeding V+ or V– via internal diodes, limiting forward current to 20mA continuous per terminal. Signals outside the rails are not passed - they trigger conduction through protection diodes to V+ or V–. To avoid damage, external current limiting (e.g., series resistors) is required if overvoltage events exceed the 20mA rating specified in Absolute Maximum Ratings.
