Analog Devices Inc./Maxim Integrated DG506ACJ+

Overview

DG506ACJ+ from Maxim Integrated is a monolithic CMOS 16-channel analog multiplexer (1-of-16) in a 28-pin plastic DIP package, operating from ±4.5V to ±18V dual supplies, with 270Ω typical on-resistance, <1nA off-leakage at +25°C, and 0.6μs switching transition time. It serves as a precision signal-routing switch in data acquisition systems requiring bidirectional analog channel selection.

For engineers reviewing the DG506ACJ+ datasheet, DG506ACJ+ pinout, DG506ACJ+ application, or DG506ACJ+ equivalent, key selection criteria include its break-before-make architecture, latch-up immunity under powered-off signal conditions, TTL/CMOS-compatible logic inputs, and guaranteed performance across 0°C to +70°C ambient.

Technical Context

The DG506ACJ+ implements a single-pole, 16-throw analog switch matrix controlled by four binary address lines (A0–A3) and an active-high enable input (EN). Its symmetrical, bidirectional operation supports equal analog signal integrity in either direction across all 16 channels.

It uses monolithic CMOS construction with internal clamping diodes to protect against overvoltage transients, and features guaranteed break-before-make timing (0.2μs minimum open interval) to prevent channel shorting during address transitions. Supply current remains below 0.25mA per rail under static conditions.

The DG506ACJ+ belongs to Maxim's legacy analog switch/multiplexer product line, designed specifically for precision, high-reliability signal routing in harsh or safety-critical environments where latch-up immunity and wide supply tolerance are mandatory.

FAQ

What is the maximum analog signal voltage range supported by the DG506ACJ+?

The DG506ACJ+ supports an analog signal range of ±15V when operated with ±15V supplies. This is specified in the Electrical Characteristics table under "Analog Signal Range" and applies across the full 0°C to +70°C operating temperature range. Signals beyond this range may forward-bias internal protection diodes, requiring external current limiting per Note 1 in the datasheet.

Does the DG506ACJ+ require external pull-up or pull-down resistors on its address inputs (A0–A3)?

No, the DG506ACJ+ does not require external biasing on A0–A3. Its address inputs are TTL- and CMOS-compatible with defined logic thresholds (VAL ≤ 0.8V for low, VAH ≥ 2.4V for high), and input currents are extremely low (±0.002μA typical), allowing direct connection to microcontroller GPIOs or FPGA outputs without additional components.

Is the DG506ACJ+ pin-compatible with the original Intersil IH6116 multiplexer?

Yes, the DG506ACJ+ is explicitly documented as a drop-in replacement for Intersil's IH6116. The pin configuration, electrical specifications, and truth table match identically, enabling direct substitution in existing designs without layout or firmware changes - confirmed in the General Description and Features sections of the Maxim datasheet.

What is the thermal derating factor for the DG506ACJ+ in its plastic DIP package?

The DG506ACJ+ in its 28-pin plastic DIP package has a continuous power dissipation rating of 1143mW at +70°C, with a derating factor of 14.3mW/°C above that temperature. This value is listed under Absolute Maximum Ratings and reflects the package's thermal resistance - critical for reliability in enclosed or high-ambient environments.

Can the DG506ACJ+ operate with asymmetric supply voltages, such as +12V and −5V?

Yes, the DG506ACJ+ can operate with asymmetric dual supplies, provided each rail stays within its absolute maximum ratings (V+ ≤ +44V, V− ≥ −44V referenced to GND) and the total differential voltage does not exceed the device's design limits. However, analog signal range becomes constrained by the smaller of |V+| or |V−|, and performance parameters like on-resistance may shift - verify against the Overtemperature Electrical Characteristics table.
