Product details
Overview
DG409AK/883B from Maxim Integrated is a dual 4-channel CMOS analog multiplexer/demultiplexer designed for precision signal routing in high-reliability systems. It features guaranteed on-resistance matching ≤8Ω, flatness ≤9Ω, low charge injection ≤15pC, max on-resistance 100Ω, and operates across ±5V to ±20V dual supplies or +5V to +30V single supply - enabling use in aerospace guidance systems requiring rail-to-rail analog signal handling.
For engineers reviewing the DG409AK/883B datasheet, DG409AK/883B pinout, DG409AK/883B application, or DG409AK/883B equivalent, key selection criteria include guaranteed channel matching, leakage <5nA at +85°C, MIL-STD-883B qualification, CERDIP-12 packaging, and compatibility with TTL/CMOS logic controls.
Technical Context
The DG409AK/883B implements dual independent 4:1 analog multiplexing paths (S1A–S4A → DA and S1B–S4B → DB) controlled by A0/A1 address lines and a shared EN enable input. Its CMOS transmission-gate architecture supports bidirectional signal flow with rail-to-rail analog voltage handling up to ±20V.
It guarantees matched on-resistance between channels (ΔrDS(ON) ≤8Ω) and flatness over signal range (rFLAT ≤9Ω), both tested per MIL-STD-883B methods. Input leakage remains <5nA at +85°C, and ESD protection exceeds 2000V per MIL-STD-883 Method 3015.7.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-channel analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG409BRZ | 16-pin SOIC, 105Ω rDS(ON), -40°C to +85°C rating, no MIL-STD-883B qualification | Not suitable for aerospace or extended-temperature military use; lacks hermetic sealing and radiation tolerance | Select ADG409BRZ only for commercial-grade instrumentation where cost and availability outweigh environmental robustness |
| HI-508AJ | 16-pin CERDIP, dual 4:1, but 200Ω rDS(ON), 30pC charge injection, ±15V max supply | Higher on-resistance degrades SNR in low-level signal paths; higher charge injection increases hold-step error | Choose HI-508AJ only if legacy board compatibility with older pinout is mandatory and performance trade-offs are acceptable |
Compared with ADG409BRZ and HI-508AJ, DG409AK/883B delivers superior channel matching (≤8Ω vs. ≥15Ω), lower charge injection (15pC vs. ≥30pC), and full MIL-STD-883B qualification - making it the sole option for flight-critical signal routing where parameter guarantees and environmental resilience are non-negotiable.

FAQ
What is the operating temperature range for DG409AK/883B?
The DG409AK/883B is rated for operation from -55°C to +125°C. This extended temperature range is verified per MIL-STD-883B test methods and makes DG409AK/883B suitable for deployment in aerospace, defense, and downhole industrial environments where thermal extremes are routine.
Is DG409AK/883B pin-compatible with the original DG409?
Yes, DG409AK/883B is a pin-compatible plug-in upgrade for the industry-standard DG409. Its 12-pin CERDIP footprint matches legacy layouts, and all signal, supply, and control pin assignments are identical - enabling drop-in replacement without PCB modification.
What supply configurations does DG409AK/883B support?
DG409AK/883B supports both dual-supply operation (±5V to ±20V) and single-supply operation (+5V to +30V). When using single supply, V− must be tied to GND. Unbalanced supplies (e.g., +24V/−5V) are also supported, provided the total V+–V− differential stays within 44V absolute maximum.
How is DG409AK/883B qualified for high-reliability applications?
DG409AK/883B undergoes full MIL-STD-883B testing including Method 3015.7 for ESD (>2000V), temperature cycling, and burn-in. Its CERDIP package provides hermetic sealing, and electrical parameters like on-resistance matching and leakage are 100% tested at hot temperature - satisfying requirements for Class B and Class S spaceflight components.
Does DG409AK/883B support bidirectional analog signal flow?
Yes, DG409AK/883B supports fully bidirectional analog signal routing on all channel pins (S1A–S4A, S1B–S4B, DA, DB). Its CMOS transmission-gate design imposes no directionality - signals pass equally well from input to output or output to input, enabling flexible use in multiplexer and demultiplexer topologies.
