Product details
Overview
DG307AAK from Vishay Siliconix is a high-reliability, dual SPDT CMOS analog switch in a 14-pin cerdip package, rated for –55 °C to +125 °C operation, with 15 V supply range, 110 ns turn-on time, and 30 Ω typical on-resistance - used in precision instrumentation signal routing where rail-to-rail analog handling and break-before-make switching are required.
For engineers reviewing the DG307AAK datasheet, DG307AAK pinout, DG307AAK application, or DG307AAK equivalent, this page delivers verified electrical specs, thermal limits, switching timing behavior, leakage performance at full temperature range, and validated alternatives for military-grade analog signal path design.
Technical Context
The DG307AAK implements two independent SPDT switches with guaranteed break-before-make action, fabricated on Vishay's PLUS-40 CMOS process to achieve micropower operation (30 nW) without compromising speed. Each switch supports bidirectional conduction and blocks up to ±15 V when off, with internal clamping diodes protecting digital inputs against overvoltage.
It operates from dual supplies (V+ = +15 V, V– = –15 V), enabling full rail-to-rail analog signal handling (–15 V to +15 V), and features CMOS-compatible logic thresholds (VINH = 11 V min, VINL = 3.5 V max) referenced to V–, ensuring robust control in mixed-signal systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | –15 V to +15 V - supports full rail-to-rail signal switching without clipping in ±15 V systems. |
| rDS(on) Typ | 30 Ω - ensures low insertion loss and minimal gain error in precision amplifier gain-switching circuits. |
| tON / tOFF | 110 ns / 70 ns - enables fast multiplexing in data acquisition and real-time control loops. |
| Supply Temp Range | –55 °C to +125 °C - qualified for extended-temperature military and aerospace applications per MIL-PRF-38535 Class B. |
| Off-Leakage (IS/ID) | ±100 nA max - preserves signal integrity in high-impedance sensor front-ends and sample-hold stages. |
| Charge Injection | 30 pC - minimizes voltage step errors in switched-capacitor and sampling circuits. |
| Power Dissipation | 825 mW (cerdip) - allows sustained operation under full load at elevated ambient temperatures with derating. |
Pinout & Package
Package: 14-pin ceramic dual-in-line (CerDIP), hermetically sealed, suitable for high-reliability and space-constrained environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 6, 9, 11 | No Connect (NC) | Internally unconnected; must be left floating or tied to GND per layout best practice. |
| 2 | V+ | Positive supply rail (+15 V typical); also substrate/case connection in metal-can variants. |
| 3, 4 | D1, D2 | Switch drain terminals - bidirectional analog outputs routed to common destination nodes. |
| 7, 14 | S1, S2 | Switch source terminals - bidirectional analog inputs connected to signal sources. |
| 10, 12 | IN1, IN2 | Digital control inputs - CMOS-level compatible (11 V/3.5 V thresholds), active-high. |
| 13 | GND | Analog/digital reference ground - separate from V– but referenced to same potential in dual-supply configuration. |
| 8 | V– | Negative supply rail (–15 V typical); defines logic low reference and enables negative analog swing. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 50 ns minimum open time between switch transitions - prevents momentary shorting in gain-select or signal-path reconfiguration. |
| Latch-up immunity | Epitaxial layer isolation eliminates latch-up risk under transient overvoltage or ESD stress - critical for ruggedized test equipment. |
| Rail-to-rail analog range | Full –15 V to +15 V signal handling - enables direct interface with op-amps and ADCs operating at ±15 V supplies. |
| Micropower operation | 30 nW quiescent power - extends battery life in portable calibration tools and field-deployable sensors. |
| Low charge injection | 30 pC - reduces settling error in precision integrators and programmable-gain amplifiers using switched feedback networks. |
Applications
| Programmable Gain Amplifier | Precision Instrumentation Multiplexer |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRZ | 8-channel single-pole switch; 70 Ω rDS(on); –40 °C to +85 °C only; SOIC-16 package. | Higher channel count but lower temperature rating and higher on-resistance - unsuitable for extended-temp military use. | Select DG307AAK when full –55 °C to +125 °C operation, low rDS(on), and break-before-make are mandatory. |
| HMC344LP3E | SPDT RF switch (DC–4 GHz); GaAs process; 50 Ω system impedance; no rail-to-rail analog support. | Optimized for RF signal routing, not precision DC/low-frequency analog - incompatible with instrumentation gain-switching. | Choose DG307AAK for DC–100 kHz analog signal control with sub-100 nA leakage and rail-to-rail capability. |
Compared with ADG408BRZ and HMC344LP3E, the DG307AAK uniquely combines military-grade temperature range, guaranteed break-before-make, 30 Ω on-resistance, and full ±15 V analog handling - making it irreplaceable in high-fidelity, high-reliability analog routing where parametric stability across extreme conditions is non-negotiable.

FAQ
What is the maximum analog signal voltage range supported by DG307AAK?
The DG307AAK supports a full rail-to-rail analog signal range of –15 V to +15 V when operated with V+ = +15 V and V– = –15 V. This range is guaranteed by design and enables direct interfacing with ±15 V op-amps and data converters. Exceeding these limits risks clamping by internal diodes or damage if current exceeds 30 mA.
Does DG307AAK require external pull-up or pull-down resistors on its digital inputs?
No, DG307AAK does not require external pull-up or pull-down resistors. Its digital inputs (IN1, IN2) are CMOS-compatible with defined thresholds (VINH ≥ 11 V, VINL ≤ 3.5 V) referenced to V–, and exhibit ultra-low input current (±1 pA typ). External biasing is unnecessary unless interfacing with open-drain logic or level-shifting circuitry.
Is DG307AAK pin-compatible with other members of the DG304A–DG307A family?
Yes, DG307AAK shares identical pinout and package (14-pin CerDIP) with DG304AAK/883, DG305AAK, and DG306AAK. All four devices use the same terminal mapping and switching logic, allowing functional substitution within the same footprint - though electrical parameters (e.g., channel count, break-before-make presence) differ per variant.
What is the meaning of the "/883" suffix in DG307AAK/883?
The "/883" suffix denotes compliance with MIL-STD-883, including screening, testing, and qualification per Method 5005 for microcircuits. DG307AAK/883 is tested for mechanical shock, vibration, temperature cycling, and burn-in, and is certified to Class B reliability standards under MIL-PRF-38535 - confirming suitability for defense and space applications.
Can DG307AAK operate from a single supply?
Yes, DG307AAK supports single-supply operation by connecting V– to 0 V and using V+ as the positive rail (up to +15 V). In this mode, the analog signal range becomes 0 V to V+, and logic inputs remain referenced to V– (ground), preserving compatibility with standard CMOS logic. However, rail-to-rail capability is lost, and negative signal handling is disabled.
