Product details
Overview
DG528CJ+ from Maxim Integrated is a monolithic, single-ended 1-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 logic inputs-designed for microprocessor-controlled data-acquisition systems requiring channel selection stability and low on-resistance (rDS(ON) < 400Ω).
For engineers reviewing the DG528CJ+ datasheet, DG528CJ+ pinout, DG528CJ+ application, or DG528CJ+ equivalent, key selection considerations include latchable address control, analog signal range (±15V), charge injection (4pC), off-isolation (68dB), and compatibility with industry-standard DG528/DG529 footprints and timing.
Technical Context
The DG528CJ+ integrates parallel N- and P-MOSFET switch structures with level-shifted digital translators, a 3-bit BCD decoder, and transparent/latched mode control via WR (write strobe) and RS (reset) inputs. It supports both microprocessor-bus interfacing and standalone analog routing.
Its internal architecture enables stable channel hold without continuous address bus driving, with guaranteed break-before-make interval of 0.2µs and switching times under 1µs (tON/tOFF). Logic thresholds remain stable across supply voltages (1.5V–1.6V typical), ensuring reliable TTL compatibility even at ±5V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports full-rail switching in dual-supply configurations without clipping |
| rDS(ON) | < 400Ω - ensures minimal voltage drop and signal distortion for precision analog signals |
| Off Isolation | 68dB - suppresses crosstalk between unselected channels up to 500kHz |
| Charge Injection | 4pC - limits output voltage glitch during channel switching in high-impedance circuits |
| Break-Before-Make Interval | 0.2µs - prevents momentary shorting of input sources during channel transitions |
| Supply Range | ±4.5V to ±20V dual or +5V to +30V single - enables flexible system-level power architecture |
| Logic Compatibility | TTL and CMOS - interfaces directly with standard microprocessor address/data buses without level shifters |
Pinout & Package
Package: 18-pin plastic DIP (0.300" wide), operating temperature range 0°C to +70°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RS) | Reset Strobe Input | Active-low signal that clears all latches and disables all channels simultaneously |
| 2 (A1) | Address Bit 1 Input | BCD address line selecting one of eight analog channels in latched mode |

| 4 (V+) | Positive Supply Rail | Accepts +5V to +30V (single) or up to +20V (dual); powers analog switches and logic |
| 5–12 (S1B–S4B, S1A–S4A) | Analog Switch Outputs | DG528CJ+ uses S1–S8 as single-ended outputs; this pinout confirms S1–S8 are channel outputs (not inputs) |
| 13 (WR) | Write Strobe Input | Latches current A2/A1/A0 address on falling edge; enables transparent mode when low |
| 14 (A0) | Address Bit 0 Input | LSB of 3-bit BCD address; determines channel selection with A1 and A2 |
| 15 (EN) | Enable Input | Active-high control enabling/disabling all switches under program control |
| 16 (V−) | Negative Supply Rail | Accepts −4.5V to −20V; required for bipolar analog signal handling |
| 17–18 (S1–S8) | Analog Switch Inputs | Eight single-ended analog inputs routed to common output D (pin 18) |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG528AKRZ | Pin-compatible 8-channel CMOS MUX; rDS(ON) = 470Ω (max), 70dB off-isolation, −40°C to +125°C rating | Better isolation and wider temp range; higher rDS(ON) increases voltage drop in high-current paths | Select for enhanced noise immunity and extended temperature operation where on-resistance tolerance allows |
| MAX4617ESA+ | Single-supply only (+2.7V to +12V); no dual-supply support; 300Ω rDS(ON); smaller 8-pin SO package | Not suitable for ±15V signal routing; optimized for low-voltage portable instrumentation | Select when system uses only positive rails and board space is constrained, but avoid for bipolar analog signal paths |
Compared with DG528CJ+, ADG528AKRZ offers superior off-isolation and extended temperature capability but trades higher on-resistance, while MAX4617ESA+ reduces footprint and supply complexity at the cost of dual-supply flexibility and reduced analog voltage range.

FAQ
What is the maximum analog signal voltage range supported by the DG528CJ+?
The DG528CJ+ supports an analog signal range of ±15V when operated with ±15V dual supplies. With single-supply configurations, it handles signals from 0V to V+, up to +30V. The device guarantees safe operation within ±4.5V to ±20V dual-supply or +5V to +30V single-supply ranges, and its analog inputs remain functional across the full rail span without damage or performance degradation-critical for the DG528CJ+ in precision data-acquisition front-ends.
Does the DG528CJ+ require external latching circuitry when used with a microprocessor?
No, the DG528CJ+ does not require external latching circuitry. It integrates on-board address latches controlled by the WR (write strobe) and RS (reset) inputs. When WR goes high, the current A2/A1/A0 address is latched and held indefinitely until reset or re-latched-enabling direct µP bus interfacing without additional ICs. This feature is intrinsic to the DG528CJ+ architecture and eliminates timing-critical glue logic in embedded systems.
What is the purpose of the break-before-make function in the DG528CJ+?
Break-before-make in the DG528CJ+ ensures that one analog channel is fully disconnected before the next is connected, preventing momentary shorting between input sources. With a guaranteed 0.2µs open interval, this function protects sensitive signal sources-such as sensors or transducers-from cross-talk, loading, or damage during switching. It is a hardwired characteristic of the DG528CJ+'s internal MOSFET gate timing and requires no external configuration.
Can the DG528CJ+ operate with TTL-level logic inputs while powered from ±5V supplies?
Yes, the DG528CJ+ maintains TTL compatibility across its full supply range, including ±5V operation. Its logic threshold remains stable at ~1.6V (with −3mV/°C tempco), well within TTL's 0.8V/2.4V VIH/VIL spec. Digital input current stays below 1µA, and inputs tolerate ±2V beyond supplies. This behavior is verified for the DG528CJ+ in both datasheet electrical characteristics and dynamic timing tables.
How does the EN (enable) pin function in the DG528CJ+?
The EN pin on the DG528CJ+ is an active-high control that globally disables all eight analog switches when low, forcing them into high-impedance off-state regardless of address or latch status. This enables software-controlled signal path isolation-especially useful when cascading multiple DG528CJ+ devices to build larger multiplexers or implementing fail-safe shutdown. EN functionality is confirmed in DG528CJ+ truth tables and timing diagrams.
