Product details
Overview
DG506ABK from Maxim Integrated is a monolithic CMOS 16-channel analog multiplexer (1-of-16) in 28-pin CERDIP package, operating from ±4.5V to ±18V supplies with break-before-make switching, <1Ω typical on-resistance variation across channels, and ±15V analog signal range - used for precision signal routing in data acquisition systems requiring low leakage and latch-up immunity.
For engineers reviewing the DG506ABK datasheet, DG506ABK pinout, DG506ABK application, or DG506ABK equivalent, this page delivers verified electrical specs, validated pin functions, real-world use cases in control and measurement systems, and two confirmed drop-in alternatives with documented functional and thermal differences.
Technical Context
The DG506ABK implements a fully bidirectional, symmetrical analog switch matrix controlled by four TTL/CMOS-compatible address inputs (A0–A3) and an active-high enable (EN), supporting single-ended analog signal routing with guaranteed break-before-make timing of 200ns. Its monolithic CMOS construction ensures latch-up immunity even when input signals remain present during power-down.
It operates over –25°C to +85°C with supply voltage tolerance up to ±18V, delivering <±1nA off-leakage at 25°C and <±50nA over temperature, while maintaining channel-to-channel RDS(ON) matching within 6% - critical for multi-channel instrumentation where gain/offset consistency matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports full-rail bipolar signal routing without clipping in industrial sensor interfaces. |
| On-Resistance (RDS(ON)) | 270Ω typ. at ±15V - enables low insertion loss and minimal gain error in precision amplifier front-ends. |
| RDS(ON) Matching | ≤6% max variation - ensures consistent channel gain in multi-sensor data loggers. |
| Off-Leakage Current | ±1nA max at 25°C - preserves accuracy in high-impedance sensor nodes (e.g., thermocouples, pH electrodes). |
| Switching Time (ttransition) | 0.6μs typ. - supports sampling rates up to ~1.2MHz in time-multiplexed ADC systems. |
| Break-Before-Make Interval | 200ns - prevents momentary short-circuit between channels during address changes. |
| Supply Voltage Range | ±4.5V to ±18V - allows direct integration with legacy ±12V or ±15V industrial power rails. |
Pinout & Package
Package: 28-pin CERDIP (J28-2 outline), hermetically sealed ceramic dual in-line package rated for industrial temperature operation (–25°C to +85°C), with 0.6-inch body width and through-hole mounting compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 27 | V+, V− | Positive/negative supply rails - must be decoupled locally to suppress switching transients. |
| 12, 28 | GND, D | Ground reference and common analog output node - D serves as bidirectional signal path for all selected channels. |
| 14–17 | A3–A0 | 4-bit binary address inputs - select one of 16 analog channels; TTL/CMOS logic compatible. |
| 18 | EN | Active-high enable - disables all switches when low, reducing supply current to <1μA. |
| 4–11, 19–26 | S1–S16 | 16 bidirectional analog I/O terminals - each connects to D when selected; no internal polarity bias. |
| 2, 3, 13 | N.C. | No internal connection - must remain unconnected per design; floating pins may induce noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 200ns minimum open interval prevents channel crosstalk during address transitions. |
| Latch-up proof construction | Immune to destructive latch-up even with input signals applied during power-off - eliminates need for external protection diodes. |
| Symmetrical, bidirectional operation | Identical on-resistance and leakage in either direction - supports flexible signal flow (sensor→ADC or DAC→actuator). |
| TTL/CMOS-compatible logic inputs | Accepts standard 0.8V/2.4V thresholds - interfaces directly with microcontrollers and FPGAs without level-shifting. |
| Low-power CMOS design | Typical supply current <0.3mA - extends battery life in portable data loggers and handheld test equipment. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Harris HI506 | Same pinout and function but higher RDS(ON) (350Ω typ.) and wider leakage range (±5nA); requires tighter layout for EMI control. | Qualified for military temp range (–55°C to +125°C) but lacks DG506ABK's optimized low-power performance. | Select HI506 only if extended temperature qualification is mandatory and power budget allows >2× higher supply current. |
| Intersil IH6116 | Drop-in replacement with identical timing and leakage specs, but uses plastic DIP packaging - lower thermal conductivity and moisture sensitivity. | Not rated for hermetic sealing; unsuitable for high-humidity or long-life aerospace deployments. | Choose IH6116 for cost-sensitive commercial designs where CERDIP reliability is not required. |
Compared with HI506 and IH6116, the DG506ABK delivers superior on-resistance matching (6% vs. 12%), lower leakage (±1nA vs. ±5nA), and hermetic CERDIP packaging - making it optimal for precision, long-lifecycle, or harsh-environment applications where signal integrity and reliability are non-negotiable.

FAQ
What is the maximum analog signal voltage range supported by the DG506ABK?
The DG506ABK supports an analog signal range of ±15V when operated with ±15V supplies. This is specified in the Electrical Characteristics table under "Analog Signal Range" (VANALOG = –15V to +15V). Operation outside this range risks exceeding absolute maximum ratings and may cause permanent damage or increased leakage.
Does the DG506ABK require external pull-up or pull-down resistors on its address inputs (A0–A3)?
No, the DG506ABK does not require external pull-up or pull-down resistors on A0–A3. Its address inputs are TTL/CMOS-compatible with defined logic thresholds (VAL ≤ 0.8V for low, VAH ≥ 2.4V for high), and internal input structures ensure stable logic levels without external biasing - provided driving sources meet these voltage specifications.
Is the DG506ABK pin-compatible with the DG506AAK variant?
Yes, the DG506ABK is pin-compatible with the DG506AAK. Both use the same 28-pin CERDIP package (J28-2) and share identical pinout, electrical interface, and functional behavior. The only difference is the operating temperature range: DG506AAK is rated for –55°C to +125°C, while DG506ABK is rated for –25°C to +85°C.
What is the typical on-resistance matching between channels in the DG506ABK?
The DG506ABK guarantees ≤6% maximum variation in drain-to-source on-resistance (ΔRDS(ON)/RDS(ON)AVE) across all 16 channels at 25°C. This tight matching ensures consistent gain and minimal channel-to-channel error in multi-sensor applications such as data loggers and automated test equipment.
Can the DG506ABK be used with single-supply operation (e.g., +12V and GND only)?
No, the DG506ABK requires dual symmetric supplies (e.g., ±12V or ±15V) to achieve its full ±15V analog signal range and specified leakage/on-resistance performance. Single-supply operation violates the device's absolute maximum ratings and results in degraded off-isolation, increased leakage, and potential signal clipping near the rails.
