Product details
Overview
DG506AAZ/883 from Vishay Siliconix is a hermetic 28-pin LCC single 16-channel CMOS analog multiplexer with TTL/CMOS-compatible control logic, 240 Ω typical on-resistance, ±15 V analog signal range, and break-before-make switching - used in high-reliability data acquisition systems requiring wide temperature operation (–55 °C to +125 °C).
For engineers reviewing the DG506AAZ/883 datasheet, DG506AAZ/883 pinout, DG506AAZ/883 application, or DG506AAZ/883 equivalent, key selection criteria include its MIL-STD-883 qualified hermetic LCC package, 44 V supply rating, 600 ns transition time, low 6 pC charge injection, and compatibility with dual-supply ±15 V operation in precision analog routing.
Technical Context
The DG506AAZ/883 implements a 4-bit binary address decoder driving 16 independent analog switches between common drain (D) and source terminals S1–S16. All switches are bidirectional, support rail-to-rail analog signals up to ±15 V, and feature epitaxial-layer latch-up immunity per Vishay's PLUS-40 process.
Enable (EN) controls global switch activation; address inputs A0–A3 select one of 16 channels with TTL/CMOS voltage thresholds (VIH = 2.4 V min, VIL = 0.8 V max). Break-before-make timing ensures no channel shorting during transitions, critical for avoiding signal glitches in multiplexed sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-rail bipolar signals without clipping in ±15 V supply systems |
| On-Resistance (rDS(on)) | 240 Ω typ - ensures minimal gain error and voltage drop in precision measurement paths |
| Transition Time | 600 ns - enables sampling rates up to ~1.2 MHz in time-multiplexed acquisition |
| Charge Injection | 6 pC - limits settling error and pedestal shift in sample-and-hold circuits |
| Off Isolation (OIRR) | 68 dB at 500 kHz - suppresses crosstalk between active and inactive channels |
| Supply Voltage Rating | ±44 V absolute max - allows robust overvoltage tolerance with external diode protection |
| Leakage Current (IS(off)) | ±50 nA max at full temp range - preserves accuracy in high-impedance sensor interfaces |
Pinout & Package
Package: 28-lead Leadless Chip Carrier (LCC), hermetically sealed, surface-mount, no leads - designed for high-reliability military/aerospace PCBs requiring moisture resistance and thermal stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | S1–S8 Source Terminals | Individual analog input/output channels; bidirectional, matched on-resistance |
| 9, 10, 11, 12, 13, 14, 15, 16 | S9–S16 Source Terminals | Continuation of 16-channel analog I/O array; electrically identical to S1–S8 |
| 17 | GND | Analog ground reference; must be low-impedance connection to minimize noise coupling |
| 18, 19, 20, 21 | A0–A3 Address Inputs | Binary-select lines determining active channel (0–15); TTL/CMOS compatible |
| 22 | EN (Enable) | Active-high global enable; disables all switches when low, preventing unintended conduction |
| 23 | D (Drain) | Common analog terminal shared across all 16 channels; connects to ADC or signal processor |
| 24, 25 | V+ / V– | Separate positive and negative supply rails; supports dual-supply ±15 V operation |
| 26, 27, 28 | NC | No-connect pins - internally unconnected; must remain floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guarantees >200 ns channel isolation during address changes - prevents momentary shorts in multi-sensor scanning |
| Hermetic LCC packaging | MIL-STD-883 qualified seal - ensures long-term reliability in humid, high-vibration, or vacuum environments |
| Low charge injection (6 pC) | Minimizes voltage step errors at S/H amplifier inputs - critical for 12+ bit data acquisition accuracy |
| Epitaxial latch-up immunity | PLUS-40 process eliminates destructive latch-up under transient overvoltage or ESD stress |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG406DJ | Plastic DIP-28, non-hermetic; same pinout but not MIL-qualified; rDS(on) = 250 Ω typ | Limited to commercial/industrial use; unsuitable for space or extended temperature deployment | Select only if cost-sensitive and operating within 0 °C to +70 °C with no humidity exposure |
| JM38510/19001BXC | Ceramic sidebraze package; identical electrical specs; different mechanical footprint and lead form | Requires PCB redesign due to sidebraze mounting; higher assembly cost but same reliability class | Choose when legacy board design mandates sidebraze interface or existing tooling supports it |
Compared with DG406DJ and JM38510/19001BXC, the DG506AAZ/883 uniquely combines LCC surface-mount compatibility, hermetic sealing, and MIL-STD-883 Class B testing - making it the only option for new high-reliability designs requiring automated assembly and extended temperature validation without footprint compromise.

FAQ
What is the maximum allowable supply voltage for DG506AAZ/883?
The DG506AAZ/883 supports a maximum supply voltage difference of 44 V between V+ and V–. With standard ±15 V operation, this provides 30 V headroom for transient overvoltage events. Absolute maximum ratings specify V+ ≤ (V–) + 44 V, and both supplies must remain within –2 V to (V+) + 2 V referenced to V–.
Does DG506AAZ/883 support single-supply operation?
No - the DG506AAZ/883 requires dual symmetric supplies (e.g., ±15 V) to achieve its specified ±15 V analog signal range and guaranteed on-resistance. Single-supply operation is not characterized or supported; attempting it results in degraded linearity, increased rDS(on), and potential damage if analog signals exceed V– or V+ rails.
How does the break-before-make timing affect system design with DG506AAZ/883?
The DG506AAZ/883 guarantees a minimum 200 ns break interval before next channel closure, preventing momentary shorts during address transitions. This requires system firmware to allow ≥200 ns settling after address change before sampling - critical for avoiding cross-channel interference in high-precision multichannel acquisition.
Is DG506AAZ/883 pin-compatible with DG406 series devices?
Yes - DG506AAZ/883 is functionally and pinout-compatible with DG406/407 in 28-pin configurations, but differs in package (hermetic LCC vs. plastic DIP) and qualification level (MIL-STD-883 vs. commercial). Electrical behavior matches closely, though DG506AAZ/883 offers superior leakage and temperature performance.
What is the purpose of the NC pins on DG506AAZ/883?
The three NC pins (26, 27, 28) on DG506AAZ/883 are internally unconnected. Vishay specifies they must remain unbonded and floating; grounding or routing them may induce parasitic coupling or violate hermetic seal integrity. PCB layout should avoid solder mask openings or traces on these pads.
