Product details
Overview
DG309AK/883B from Maxim Integrated is a quad, single-pole-single-throw (SPST), normally closed (NC) analog switch in 16-pin CERDIP package, rated for -55°C to +125°C operation, with 60Ω typical on-resistance, <120ns turn-on time, and ±44V maximum breakdown voltage - used in military radios and guidance systems requiring high-reliability signal routing under extreme temperature conditions.
For engineers reviewing the DG309AK/883B datasheet, DG309AK/883B pinout, DG309AK/883B application, or DG309AK/883B equivalent, key selection criteria include NC configuration, MIL-STD-883B qualification, 16-pin CERDIP hermetic packaging, guaranteed operation across -55°C to +125°C, and compatibility with split (±5V to ±20V) or single (+5V to +30V) supplies.
Technical Context
The DG309AK/883B implements four independent SPST NC switches using monolithic CMOS process technology, enabling bidirectional analog signal switching with rail-to-rail analog voltage range up to ±15V when operated with dual supplies. Its CMOS-compatible logic inputs draw <1µA leakage at full temperature range and support direct interfacing with TTL or CMOS controllers.
Each channel exhibits matched on-resistance (<100Ω max over temperature), low charge injection (±10pC), and high off-isolation (78dB at 500kHz), making it suitable for precision sample-and-hold and multiplexed test instrumentation where signal integrity and timing fidelity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally closed (NC) - all four channels conduct when control input is logic low. |
| On-Resistance (rDS(ON)) | 60Ω typical at V+ = +15V, V− = −15V - ensures minimal signal attenuation in low-voltage analog paths. |
| Turn-On / Turn-Off Time | 130ns / 90ns typical - supports >5MHz switching in time-critical sampling applications. |
| Analog Signal Range | ±15V with dual supply - allows full-rail signal handling without clipping in ±15V op-amp systems. |
| Supply Voltage Range | Single: +5V to +30V; Dual: ±5V to ±20V - enables flexible integration into legacy and modern power architectures. |
| Operating Temperature | −55°C to +125°C - qualified per MIL-STD-883B, meeting extended-range requirements for aerospace and defense platforms. |
| Breakdown Voltage | 44V maximum (V+ to V−) - provides 30V peak-to-peak blocking capability in off-state, enhancing system fault tolerance. |
Pinout & Package
Package: 16-pin CERDIP (Ceramic Dual In-line Package), hermetically sealed, MIL-STD-883B qualified, 0.3-inch wide body, 0.1-inch lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Logic control inputs | CMOS/TTL-compatible; low = channel ON (NC), high = channel OFF - direct microcontroller GPIO interface without level-shifting. |
| S1–S4 (Pins 3, 6, 11, 14) | Source terminals | Input side of each switch; bidirectional - may serve as input or output depending on signal flow direction. |
| D1–D4 (Pins 2, 7, 10, 15) | Drain terminals | Output side of each switch; electrically identical to source - supports symmetrical analog signal routing. |
| V+ (Pin 13) | Positive supply / substrate connection | Must be connected to most positive rail; ties internal substrate - critical for latch-up immunity and breakdown rating. |
| V− (Pin 4) | Negative supply | Required for dual-supply operation; sets lower analog rail - floating in single-supply mode (GND referenced). |
| GND (Pin 5) | Ground reference | System ground return for logic and supply currents - must be low-impedance path to minimize noise coupling. |
| N.C. (Pin 12) | No connect | Not internally bonded - left unconnected; no routing or termination required on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic CMOS construction | Eliminates discrete component matching errors and reduces board area vs. discrete FET switch arrays. |
| Low charge injection (±10pC) | Minimizes voltage glitch in sample-and-hold circuits, preserving DC accuracy after switching events. |
| High off-isolation (78dB @ 500kHz) | Prevents crosstalk between active and inactive channels in dense multiplexer designs. |
| CMOS logic-compatible inputs | Supports direct drive from 3.3V or 5V microcontrollers without external pull-ups or buffers. |
| Bipolar or single-supply operation | Enables reuse across legacy ±15V test equipment and modern +12V embedded systems without redesign. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG409BRZ | Quad SPST NC, 35Ω rDS(ON), −40°C to +85°C, SOIC-16 - lacks MIL-STD-883B qualification and extended temperature range. | Targeted at commercial industrial test gear; not approved for flight-critical or deployed military hardware. | Select ADG409BRZ only if cost, volume availability, or commercial-grade temp range suffice for non-mission-critical use. |
| MAX4677CWI+ | Quad SPST NC, 4.5Ω rDS(ON), −40°C to +85°C, TSSOP-16 - lower on-resistance but no hermetic packaging or extended temperature rating. | Optimized for low-distortion audio or high-resolution data acquisition where on-resistance dominates error budget. | Choose MAX4677CWI+ when ultra-low rDS(ON) is mandatory and environmental ruggedness is secondary to signal purity. |
Compared with ADG409BRZ and MAX4677CWI+, the DG309AK/883B uniquely delivers MIL-STD-883B qualification, −55°C to +125°C operation, and hermetic CERDIP packaging - essential for aerospace, defense, and high-reliability embedded systems where field failure is unacceptable.

FAQ
What does the "/883B" suffix indicate in DG309AK/883B?
The "/883B" suffix denotes full compliance with MIL-STD-883B, Method 5005, including screening for mechanical shock, thermal cycling, and burn-in. DG309AK/883B undergoes rigorous testing to ensure performance stability across -55°C to +125°C and meets DLA-approved QML-38534 requirements for Class B hybrid microcircuits.
Is DG309AK/883B pin-compatible with DG308AK/883B?
Yes, DG309AK/883B shares identical pinout and package with DG308AK/883B, differing only in logic polarity: DG309AK/883B is normally closed (NC), while DG308AK/883B is normally open (NO). Both use the same 16-pin CERDIP footprint and electrical interface, enabling layout reuse in dual-configuration designs.
Can DG309AK/883B operate from a single +12V supply?
Yes, DG309AK/883B supports single-supply operation from +5V to +30V. When using +12V, GND serves as the negative reference, V− pin is left unconnected, and analog signals must remain within 0V to +12V. Note that rDS(ON) increases slightly versus dual-supply operation, and switching speed degrades modestly.
What is the maximum analog signal voltage DG309AK/883B can switch?
DG309AK/883B supports analog signals up to ±15V when operated with ±15V dual supplies. With single +30V supply, the maximum analog swing is 0V to +30V. The absolute maximum rating is 44V between V+ and V−, limiting peak-to-peak blocking to 30V in off-state - exceeding this risks permanent damage.
Does DG309AK/883B require external pull-up or pull-down resistors on its logic inputs?
No, DG309AK/883B features CMOS-compatible inputs with leakage <1µA across temperature, eliminating need for external biasing. Logic inputs accept 0V–0.8V as low and 2.0V–V+ as high; direct connection to microcontroller GPIOs or FPGA outputs is fully supported without additional components.
