Product details
Overview
DG506AAK/883 from Vishay Siliconix is a single 16-channel CMOS analog multiplexer with TTL/CMOS-compatible control inputs, 240 Ω typical on-resistance, 44 V supply rating, and –55 °C to +125 °C operating range in hermetic 28-pin CerDIP packaging. It routes analog signals in precision data acquisition systems where low crosstalk and break-before-make switching are required.
For engineers reviewing the DG506AAK/883 datasheet, DG506AAK/883 pinout, DG506AAK/883 application, or DG506AAK/883 equivalent, key selection criteria include guaranteed on-resistance matching (±6%), off-isolation (68 dB at 500 kHz), charge injection (6 pC), transition time (600 ns), and compatibility with ±15 V dual supplies in military-grade environments.
Technical Context
The DG506AAK/883 implements a 4-bit binary address decoder driving 16 independent analog switches between common drain (D) and source terminals (S1–S16). All switches feature symmetrical bidirectional conduction and rail-to-rail analog signal handling up to ±15 V when powered from ±15 V supplies.
Its enable (EN) input supports cascading of multiple devices; break-before-make timing prevents momentary shorting during channel transitions; and the PLUS-40 fabrication process provides latch-up immunity and enhanced ESD robustness suitable for high-reliability applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-rail analog signals without clipping when V+ = +15 V, V– = –15 V |
| On-Resistance (rDS(on)) | 240 Ω typ - ensures minimal voltage drop and gain error in precision signal paths |
| On-Resistance Matching | ±6 % - enables accurate ratio-metric measurements across channels |
| Transition Time | 600 ns - defines maximum switching speed for time-critical multiplexed sampling |
| Off Isolation (OIRR) | 68 dB at 500 kHz - suppresses crosstalk between active and inactive channels |
| Charge Injection | 6 pC - limits voltage glitch on sample-and-hold capacitors during switching |
| Supply Voltage Rating | ±44 V max - allows operation with overvoltage-protected supplies or wide-range bipolar rails |
Pinout & Package
Package: 28-pin Ceramic Dual-In-Line (CerDIP), hermetically sealed, MIL-STD-883 qualified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–8, 21–28 | S1–S8, S9–S16 | 16 analog source terminals - bidirectional, rail-to-rail capable, each independently selectable |
| 9 | D | Common analog drain terminal - connects to ADC input, amplifier output, or signal bus |
| 10–13 | A0–A3 | 4-bit binary address inputs - select one of 16 channels (S1–S16) when EN = high |
| 14 | EN | Enable input - high enables decoding; low disables all switches (high-Z state) |
| 15, 16 | V+, V– | Positive/negative power supply pins - support ±5 V to ±22 V dual supplies |
| 17 | GND | Analog ground reference - must be tied to system AGND for optimal noise performance |
| 18–20, 22 | NC | No-connect pins - internally unconnected; must remain floating or grounded per design guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 200 ns minimum open interval prevents signal shorting during channel changes |
| Latch-up immunity | Epitaxial substrate eliminates parasitic SCR activation under transient overvoltage conditions |
| TTL/CMOS logic compatibility | Input thresholds (VIH ≥ 2.4 V, VIL ≤ 0.8 V) interface directly with standard digital controllers without level shifting |
| Low system crosstalk | 68 dB off-isolation at 500 kHz ensures <0.4 % signal coupling between adjacent channels |
| Hermetic MIL-STD-883 qualification | Validated for extended temperature range (–55 °C to +125 °C) and long-term reliability in aerospace and defense systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG406ACJ | Plastic DIP package; same pinout but non-hermetic; rated –40 °C to +85 °C only | Not qualified for extended temperature or vacuum environments; unsuitable for space or avionics | Select DG406ACJ only for commercial-grade cost-sensitive designs with relaxed environmental requirements |
| JM38510/19001BXC | 28-pin sidebraze ceramic package; identical electrical specs; different mechanical footprint and lead form | Requires PCB redesign due to sidebraze mounting; used in legacy DoD hardware with specific procurement mandates | Choose JM38510/19001BXC when compliance with MIL-PRF-38535 Class B or specific board assembly standards is mandatory |
Compared with DG406ACJ and JM38510/19001BXC, the DG506AAK/883 uniquely combines hermetic CerDIP packaging, full –55 °C to +125 °C operation, and MIL-STD-883 testing in a through-hole DIP format compatible with legacy ATE and defense system assemblies.

FAQ
What is the maximum allowable analog signal voltage range for DG506AAK/883?
The DG506AAK/883 supports analog signals from V– to V+, with guaranteed operation up to ±15 V when powered from ±15 V supplies. Its absolute maximum rating allows ±44 V differential supply voltage, and analog inputs may swing within (V–) –2 V to (V+) +2 V, clamped by internal protection diodes. For reliable long-term use, analog signals should remain within the supply rails unless external overvoltage protection is implemented.
Does DG506AAK/883 support bidirectional analog signal flow?
Yes, DG506AAK/883 supports fully bidirectional analog signal flow. Each channel conducts equally well in both directions when enabled, with symmetric on-resistance and leakage characteristics. This enables flexible routing architectures such as shared ADC inputs or dual-path sensor interfaces without polarity constraints, provided the analog voltage remains within the specified (V–) –2 V to (V+) +2 V range.
What is the purpose of the EN (enable) pin on DG506AAK/883?
The EN pin on DG506AAK/883 controls global switch activation: when high, it enables the address decoder to route the selected Sx channel to D; when low, all 16 switches are placed in a high-impedance off-state regardless of address inputs. This allows multiple DG506AAK/883 devices to share a common D line while being individually selected, simplifying system-level multiplexer expansion without additional logic gates.
How does DG506AAK/883 handle charge injection during switching?
DG506AAK/883 specifies 6 pC typical charge injection, which represents the net charge transferred to the output node during channel turn-on/off transitions. This value is critical in sample-and-hold and switched-capacitor circuits, where injected charge causes voltage glitches. The low 6 pC figure-achieved via matched transistor geometry and layout symmetry-minimizes settling errors and supports accurate 12-bit+ data acquisition when paired with appropriate hold capacitor sizing.
Is DG506AAK/883 pin-compatible with DG406 series devices?
Yes, DG506AAK/883 is pin-compatible with DG406ACJ and DG406ADJ plastic-package variants, sharing identical pin assignments, logic behavior, and electrical specifications except for temperature range and packaging. However, DG506AAK/883 uses hermetic CerDIP construction and is qualified to –55 °C to +125 °C per MIL-STD-883, whereas DG406 devices are commercial-grade and limited to –40 °C to +85 °C.
