Product details
Overview
DG406DJ from Intersil is a single 16-channel CMOS analog multiplexer with TTL/CMOS-compatible digital control, ±15V dual-supply operation, <100Ω ON-resistance, <300ns transition time, and low charge injection (40pC). It serves as a drop-in replacement for DG506A in data acquisition systems requiring high channel count and bidirectional signal routing.
For engineers reviewing the DG406DJ datasheet, DG406DJ pinout, DG406DJ application, or DG406DJ equivalent, key selection criteria include its 16:1 analog switching capability, 44V max supply range, -40°C to +85°C operating temperature, and PDIP-28 package compatibility with legacy test equipment layouts.
Technical Context
The DG406DJ integrates a 4-bit binary decoder driving 16 bilateral analog switches, with internal voltage reference for stable logic thresholds across supply variations. Its silicon-gate process enables latch-up immunity and supports ±15V supplies while maintaining low rDS(ON) variation (<5% matching) over ±5V analog input range.
It features active-high ENABLE control, no-connect pins for package flexibility, and operates with single (0–12V) or split (±15V) supplies. Charge injection reduction simplifies sample-and-hold design, and OFF-isolation exceeds -69dB at 100kHz - critical for high-precision multiplexed ADC front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | 16-channel single-ended (1-of-16) analog multiplexer - routes one of sixteen bidirectional analog signals to common drain D. |
| ON-Resistance (rDS(ON)) | Max 100Ω at ±10V signal, 25°C - ensures minimal gain error and channel-to-channel crosstalk in precision sensor multiplexing. |
| Transition Time (tTRANS) | Max 300ns (bipolar), 450ns (single-supply) - enables >1MHz multiplexing rates in automated test equipment. |
| Charge Injection | Typ 40pC - reduces hold capacitor settling error, easing design of 12-bit+ sample-and-hold circuits. |
| Supply Voltage Range | ±15V max (44V V+ to V−), or 0–12V single supply - supports industrial ±10V signal ranges and battery-powered 5V/12V systems. |
| Logic Compatibility | TTL and CMOS inputs (VINH ≥ 2.4V, VINL ≤ 0.8V) - interfaces directly with microcontrollers and FPGAs without level-shifting. |
| Operating Temperature | -40°C to +85°C - qualified for medical instrumentation and industrial embedded environments. |
Pinout & Package
Package: 28-lead PDIP (Plastic Dual-In-Line), JEDEC MS-011-AB, body size 1.380" × 0.600", lead pitch 0.100". RoHS-compliant matte tin plating.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive power supply rail - must be ≥ |V−| and ≤ 44V above V−; powers analog switches and decode logic. |
| 2, 3, 13 | NC | No internal connection - left unconnected; electrically isolated per datasheet pin description. |
| 4–11 | S16–S9 | Analog source terminals - bidirectional; accept or deliver analog signals up to ±15V when V+ = +15V, V− = −15V. |
| 12 | GND | Ground reference - connects to system 0V plane; required for logic threshold stability and noise immunity. |
| 14–17 | A3–A0 | 4-bit address inputs - binary-encoded channel select (A3 MSB); A0 LSB determines S1/S2 activation per truth table. |
| 18 | EN | Active-high enable - drives all switches OFF when low; enables decoding only when high. |
| 19–26 | S1–S8 | Analog source terminals - identical function to S9–S16; completes full 16-channel set. |
| 27 | V− | Negative power supply rail - referenced to GND in single-supply mode (tie to 0V); sets lower analog signal limit. |
| 28 | D | Common drain terminal - bidirectional analog I/O node; connected to ADC input or buffer output in typical applications. |
Key Features
| Feature | Design Value |
|---|---|
| Bilateral analog switching | 16 fully bidirectional channels support AC-coupled and DC-coupled signals equally - eliminates polarity constraints in mixed-signal routing. |
| Low ON-resistance variation | ΔrDS(ON) ≤ 5% between channels - maintains consistent gain and offset across all 16 paths in multi-sensor systems. |
| Latch-up immunity | Epitaxial layer prevents SCR-triggered latch-up - enables robust operation in noisy industrial environments with supply transients. |
| Low leakage current | ID(OFF) ≤ 40nA (max, full temp range) - minimizes signal corruption in high-impedance sensor interfaces (e.g., thermocouples, pH electrodes). |
| Pb-free / RoHS compliant | Matte tin (e3) termination, MSL3 rated - supports lead-free wave soldering and meets global environmental compliance requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX306CPN | 16-channel, ±20V max supply, 120Ω rDS(ON), 400ns tTRANS, SOIC-28 only | Higher ON-resistance and slower switching; requires PCB redesign for SOIC footprint | Select for wider supply range where 120Ω rDS(ON) is acceptable and PDIP layout change is not feasible. |
| ADG506AKNZ | 16-channel, ±15V supply, 125Ω rDS(ON), 350ns tTRANS, 28-lead PDIP, higher leakage (100nA ID(OFF)) | Higher leakage and resistance degrade accuracy in high-Z sensor applications | Prefer when sourcing ADI ecosystem compatibility is prioritized over lowest leakage or fastest switching. |
Compared with DG406DJ, MAX306CPN offers extended voltage range but sacrifices speed and resistance performance, while ADG506AKNZ matches the PDIP package but trades off leakage and ON-resistance - making DG406DJ optimal for precision, low-leakage, and fast-switching 16:1 multiplexing in legacy PDIP designs.

FAQ
What is the maximum analog signal voltage range supported by the DG406DJ?
The DG406DJ supports analog signals from V− to V+, with absolute maximum V+ to V− rating of 44V. When operated at ±15V supplies, it handles ±15V (30VP-P) analog signals. In single-supply mode (e.g., V+ = 12V, V− = 0V), the usable analog range is 0V to 12V. Exceeding these limits risks damage or degraded rDS(ON) performance.
Does the DG406DJ require external level-shifting for TTL-compatible microcontroller control?
No. The DG406DJ has native TTL/CMOS-compatible logic inputs: VINH ≥ 2.4V and VINL ≤ 0.8V, matching standard 5V TTL and 3.3V/5V CMOS outputs. No external level shifters are needed when interfacing with common MCUs, FPGAs, or CPLDs operating at those logic levels.
How does the DG406DJ handle power supply sequencing during startup?
The DG406DJ has no strict sequencing requirement. Its internal voltage reference and logic circuitry operate correctly as long as V+ and V− stabilize within specification before applying digital control signals. However, applying EN or address inputs before supplies settle may cause undefined channel states - best practice is to assert EN only after V+ and V− are stable.
Can the DG406DJ be used in single-supply configurations with ground-referenced signals?
Yes. Tie V− to GND and apply V+ = 5V, 12V, or up to 24V (within 44V V+–V− limit). Analog inputs then swing from 0V to V+. The device maintains <120Ω rDS(ON) and low leakage in this mode, as verified in single-supply electrical specs (e.g., rDS(ON) = 90–120Ω at V+ = 12V).
What is the thermal resistance (θJA) of the DG406DJ in its PDIP package?
The DG406DJ in 28-lead PDIP has θJA = 60°C/W under JEDEC low-thermal-conductivity board conditions. This value assumes free-air convection and standard PCB mounting; actual junction temperature rise depends on copper area, airflow, and ambient conditions. Maximum junction temperature is +150°C.
