Product details
Overview
DG529CJ+ from Maxim Integrated is a differential 2-of-8 CMOS analog multiplexer with on-board address latches, break-before-make switching, ±4.5V to ±20V dual-supply or +5V to +30V single-supply operation, and TTL/CMOS-compatible digital inputs - designed for precision data-acquisition systems requiring channel isolation and microprocessor bus interfacing.
For engineers reviewing the DG529CJ+ datasheet, DG529CJ+ pinout, DG529CJ+ application, or DG529CJ+ equivalent, key selection criteria include its differential input architecture, 400Ω max rDS(ON), 0.2µs break-before-make interval, 4pC charge injection, and compatibility with legacy DG529 and ADG529 families in 18-pin plastic DIP packaging.
Technical Context
The DG529CJ+ implements a latch-based decoding architecture with A0/A1 address inputs, EN enable, WR write strobe, and RS reset control - enabling transparent or latched operation modes. Its internal parallel N/P MOSFET switch structure supports bidirectional analog signal routing across four differential pairs (IN1A/IN1B through IN4A/IN4B).
It features dual-mode digital interface logic: TTL-compatible thresholds (~1.6V) with -3mV/°C tempco, ESD protection via 30V zener clamps, and ±2V overvoltage tolerance on digital inputs. Analog signal range spans V– to V+, with guaranteed performance from 0°C to +70°C.

FAQ
What is the maximum analog signal voltage range supported by the DG529CJ+?
The DG529CJ+ supports an analog signal range from V– to V+. With ±15V supplies, it handles ±15V signals; with +15V/–5V asymmetrical supplies, it routes signals from –5V to +15V. The DG529CJ+ datasheet specifies absolute maximum analog voltage as ±15V under standard operating conditions, and the device maintains specified rDS(ON) and leakage performance across this full range when powered within its supply limits.
Does the DG529CJ+ require external latching circuitry when used with a microprocessor?
No, the DG529CJ+ does not require external latching circuitry. It integrates on-board address latches controlled by WR (write) and RS (reset) strobes, allowing it to retain channel selection independently of continuous address bus drive. This feature simplifies interface with 8080/8085-style microprocessors and eliminates the need for external 74HC373 or similar latch ICs in the DG529CJ+ signal path.
How does the break-before-make function operate in the DG529CJ+?
The DG529CJ+ guarantees a minimum 0.2µs break interval between channel disconnect and reconnect during address changes. This timing prevents momentary shorting between differential input pairs (e.g., IN1A/IN1B to IN2A/IN2B), preserving signal integrity in sensitive measurement circuits. The interval is internally generated and independent of external timing - no additional delay circuitry is needed to ensure safe switching in the DG529CJ+.
Can the DG529CJ+ operate from a single +5V supply?
Yes, the DG529CJ+ operates from a single +5V to +30V supply. When using +5V, connect V– to GND. Digital inputs remain TTL-compatible (threshold ~1.5V), and analog range becomes 0V to +5V. Note that rDS(ON) increases and switching speed decreases versus ±15V operation, but break-before-make action and latch functionality remain fully functional across the entire single-supply range for the DG529CJ+.
Is the DG529CJ+ pin-compatible with the ADG529 series?
Yes, the DG529CJ+ is pin and electrically compatible with the ADG529 family in 18-pin DIP packaging, as confirmed in the Maxim datasheet. Both share identical pinout, supply requirements, logic thresholds, and switching characteristics. However, ADG529 devices exhibit higher typical rDS(ON) (600Ω vs. 400Ω for DG529CJ+) and different charge injection (6pC vs. 4pC), so system-level validation is recommended before substitution in high-precision DG529CJ+ applications.
