Product details
Overview
DG423DJ from Maxim Integrated is a dual, single-pole/double-throw (SPDT) CMOS analog switch with latchable TTL/CMOS-compatible control inputs, designed for precision signal routing in mixed-signal systems. It features 20Ω typical on-resistance, 3Ω maximum on-resistance matching between channels, 15pC maximum charge injection, rail-to-rail analog signal handling (±15V), and operates from ±4.5V to ±20V bipolar or +10V to +30V single supply - ideal for battery-powered test equipment and telecom interface modules.
For engineers reviewing the DG423DJ datasheet, DG423DJ pinout, DG423DJ application, or DG423DJ equivalent, key selection criteria include guaranteed rDS(ON) match (≤3Ω), break-before-make timing (10–15ns), low leakage (<5nA at +85°C), latch-controlled logic interface, and 16-pin plastic DIP packaging for through-hole prototyping and industrial control boards.
Technical Context
The DG423DJ implements two independent SPDT switches with integrated transparent latches controlled by WR (Write) and RS (Reset) signals, enabling microprocessor-compatible operation without external clocking. Each switch supports bidirectional analog conduction, exhibits <4Ω on-resistance flatness over full signal range, and maintains guaranteed performance across –40°C to +85°C.
Its internal architecture uses silicon-gate CMOS process with substrate tied to V+, delivering 2000V ESD tolerance (per Method 3015.7), 35µW max power consumption, and 175ns tON/145ns tOFF switching - optimized for sample-and-hold circuits and audio multiplexing where timing integrity and signal fidelity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| rDS(ON) (typ) | 20Ω - ensures minimal signal attenuation and distortion in precision analog paths |
| ∆rDS(ON) (max) | 3Ω - guarantees matched gain/phase response between dual SPDT channels |
| Charge injection (max) | 15pC - limits voltage glitch in sample-and-hold and ADC front-end applications |
| tON/tOFF | 175ns/145ns - enables fast channel switching in real-time signal routing systems |
| Analog signal range | ±15V - supports rail-to-rail operation with ±15V supplies, preserving dynamic range |
| Off leakage (max @ +85°C) | 5nA - maintains high isolation in high-impedance sensor interfaces and PBX line cards |
| Supply range | ±4.5V to ±20V bipolar or +10V to +30V single - simplifies power architecture in multi-rail systems |
Pinout & Package
Package: 16-pin plastic DIP (0.300" wide), -40°C to +85°C operating temperature range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | D1, D2 | Drain terminals - bidirectional analog outputs for SPDT switch 1 and 2 |
| 2 | WR | Write select - latches IN1/IN2 states into internal flip-flops on rising edge |
| 3, 4, 5, 6 | N.C. | No internal connection - unconnected pins; must remain floating or grounded per layout best practice |
| 7 | RS | Reset select - forces both switches to OFF state (IN = 0) when asserted high |
| 9, 16 | S1, S2 | Source terminals - common analog inputs for SPDT switch 1 and 2 |
| 10, 15 | IN1, IN2 | Control inputs - determine NO/NC path selection for each SPDT switch (TTL/CMOS compatible) |
| 11 | V+ | Positive supply - powers analog switch core; must be sequenced first during power-up |
| 12 | VL | Logic supply - fixed +5V reference for input threshold definition and latch operation |
| 13 | GND | Ground - reference for VL and digital logic; separate from analog return in mixed-signal layouts |
| 14 | V- | Negative supply - completes bipolar supply rail; enables true rail-to-rail analog swing |
Key Features
| Feature | Design Value |
|---|---|
| Latchable digital interface | WR/RS control eliminates need for continuous µP bus hold; reduces system timing overhead |
| Guaranteed rDS(ON) match | ≤3Ω between channels ensures balanced differential signal paths in instrumentation front-ends |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - preserves full dynamic range in ±15V op-amp systems |
| Low charge injection | 15pC max minimizes sampling error in precision data acquisition and audio switching |
| ESD robustness | 2000V HBM rating enables reliable handling in automated assembly and field-repair environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG423BRZ | Single-supply only (+3V to +16V); no bipolar support; 4.5Ω rDS(ON) match; 16-pin SOIC package | Lacks latch logic; requires continuous control bus drive; better suited for low-voltage portable designs | Select when system uses only positive supply and space-constrained PCB layout favors SOIC |
| MAX4623ESE+ | CMOS SPDT with enable (no latch); 3.5Ω rDS(ON) match; 16-pin QSOP; RoHS-compliant | Non-latching interface increases µP I/O demand; lower 12V max supply limits high-voltage signal handling | Choose for cost-sensitive industrial controls needing RoHS compliance and simplified logic interface |
Compared with DG423DJ, ADG423BRZ offers smaller footprint but sacrifices bipolar operation and latch functionality, while MAX4623ESE+ provides RoHS compliance and tighter rDS(ON) match yet lacks the microprocessor-friendly latch architecture essential for burst-mode signal routing.

FAQ
What is the operating temperature range for the DG423DJ?
The DG423DJ is rated for –40°C to +85°C operation, validated across its full electrical specification range including on-resistance, leakage, and switching timing. This makes DG423DJ suitable for industrial control panels and outdoor telecom equipment where ambient thermal stress exceeds commercial-grade limits.
Does the DG423DJ require a separate logic supply voltage?
Yes, the DG423DJ requires VL = +5V as a dedicated logic supply to define TTL-compatible input thresholds and power internal latches. Connecting VL to V+ or other voltages disables guaranteed logic-level compatibility - DG423DJ functionality depends on this fixed +5V reference for correct WR/RS/IN interpretation.
How does the latch function work on the DG423DJ?
The DG423DJ uses WR (Write) and RS (Reset) inputs to control transparent latching: asserting WR captures the current IN1/IN2 states into internal flip-flops, while asserting RS forces both switches OFF regardless of IN state. This allows DG423DJ to maintain channel configuration without continuous µP bus activity - critical for low-power wake-on-event systems.
Can the DG423DJ operate from a single +12V supply?
Yes, the DG423DJ supports single-supply operation from +10V to +30V. With V+ = +12V and V− tied to GND, DG423DJ delivers rail-to-rail analog switching from 0V to +12V. However, bipolar operation (e.g., ±15V) is required to guarantee ∆rDS(ON) ≤3Ω and rFLAT(ON) ≤4Ω per datasheet specifications.
What is the maximum analog signal voltage the DG423DJ can handle?
The DG423DJ supports analog signals from V− to V+, with absolute maximum ratings of V+ ≤ +44V and V− ≥ –44V relative to GND. Under standard ±15V operation, DG423DJ handles ±15V signals with full specification compliance - exceeding typical op-amp output rails and enabling direct interfacing with industrial transducers.
