Product details
Overview
DG307AAK/883 from Vishay Siliconix is a radiation-hardened, high-reliability dual SPDT analog switch IC designed for precision signal routing in military and aerospace systems. It features 15-V input range, 110 ns turn-on time, 30 Ω typical rDS(on), –55°C to +125°C operating temperature, and 14-pin cerdip package with metal can shielding.
For engineers reviewing the DG307AAK/883 datasheet, DG307AAK/883 pinout, DG307AAK/883 application, or DG307AAK/883 equivalent, this part supports rail-to-rail analog switching, break-before-make timing, low charge injection (30 pC), and CMOS-compatible logic control in harsh-environment instrumentation and avionics signal paths.
Technical Context
The DG307AAK/883 implements two independent SPDT switches using Vishay's PLUS-40 CMOS process, enabling symmetric bidirectional conduction with guaranteed break-before-make operation. Each switch exhibits flat on-resistance over ±15 V analog range and supports single-supply operation when V– is tied to ground.
It integrates epitaxial latchup protection, internal clamping diodes for overvoltage tolerance (V– –2 V to V+ +2 V), and micropower operation (30 nW quiescent). Digital inputs accept 3.5 V/11 V logic thresholds and drive S1/S2 and D1–D4 terminals with full rail-to-rail analog signal handling.

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 |
|---|---|---|---|
| JM38510/11608BCA | 10-pin metal can package, identical electrical specs, same –55°C to +125°C rating | Limited to single SPDT per package; requires two units for dual functionality | Select when board space allows discrete can packages and legacy footprint compatibility is required |
| DG307ABK | Same die, –25°C to +85°C rating, 14-pin cerdip but non-883 compliant | Not radiation-hardened; lacks MIL-PRF-38535 qualification and burn-in screening | Use only in commercial or industrial environments where radiation tolerance and extended temp are not required |
Compared with DG307AAK/883, JM38510/11608BCA offers identical analog performance but requires duplication for dual-switch function and occupies more PCB area, while DG307ABK sacrifices radiation hardness and extended temperature capability for cost reduction in non-military designs.

FAQ
What is the maximum analog signal voltage range supported by the DG307AAK/883?
The DG307AAK/883 supports a full rail-to-rail analog signal range of ±15 V when operated with V+ = +15 V and V– = –15 V. This is guaranteed by design and enables undistorted switching of signals spanning the entire supply rails without clipping or compression, making it suitable for high-fidelity sensor interface applications.
Does the DG307AAK/883 require external pull-up or pull-down resistors on its logic inputs?
No, the DG307AAK/883 does not require external pull-up or pull-down resistors on IN1 or IN2. Its CMOS-compatible inputs have negligible leakage (±1 pA typical) and defined logic thresholds (3.5 V low, 11 V high), allowing direct connection to TTL or CMOS logic drivers without additional biasing components.
How is break-before-make timing ensured in the DG307AAK/883?
Break-before-make timing in the DG307AAK/883 is guaranteed by internal circuit design and process-controlled propagation delays, with a minimum tOPEN of 50 ns specified at room temperature. This prevents simultaneous conduction between S1/D1 and S2/D2 paths, eliminating transient shorts during switching transitions in critical analog routing.
Can the DG307AAK/883 operate from a single supply?
Yes, the DG307AAK/883 supports single-supply operation: tie V– to ground and apply V+ between 5 V and 15 V. In this configuration, the analog signal range becomes 0 V to V+, maintaining rail-to-rail operation and CMOS logic compatibility, ideal for portable test equipment and battery-powered instrumentation.
What packaging and screening level does the /883 suffix indicate for DG307AAK/883?
The /883 suffix on DG307AAK/883 denotes compliance with MIL-STD-883, including full microcircuit screening for Class B reliability: temperature cycling, burn-in, steady-state life test, and radiation hardness assurance (RHA) up to 100 krad(Si). It is supplied in a hermetically sealed 14-pin cerdip package with metal can lid.
