Product details
Overview
DG507ACWI+ from Maxim Integrated is a monolithic CMOS differential 8-channel (2-of-16) analog multiplexer with break-before-make switching, ±4.5V to ±18V dual-supply operation, 270Ω typical on-resistance at ±15V, and <1µs switching transition time. It serves as a bidirectional signal routing device in precision data acquisition systems requiring low leakage and rail-to-rail analog signal handling.
For engineers reviewing the DG507ACWI+ datasheet, DG507ACWI+ pinout, DG507ACWI+ application, or DG507ACWI+ equivalent, key selection criteria include its differential channel architecture, guaranteed latch-up immunity under powered-off signal conditions, wide supply range compatibility, and drop-in replacement status for legacy IH6216 and HI507 devices.
Technical Context
The DG507ACWI+ implements a fully symmetrical, bidirectional analog switch matrix controlled by four TTL/CMOS-compatible address inputs (A0–A3) and an active-high enable input (EN). Its internal architecture enforces break-before-make timing (tOPEN = 0.2µs) to prevent signal shorting during channel transitions.
It features latch-up proof construction per JEDEC JESD78, operates with analog signal ranges spanning ±15V (VANALOG = –15V to +15V), and maintains channel-to-channel RDS(ON) matching within 6% across temperature. Off-isolation exceeds 68dB at 500kHz, supporting high-fidelity signal routing in mixed-signal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - Supports rail-to-rail input/output signals without clipping when V+ = +15V and V− = −15V. |
| On-Resistance (RDS(ON)) | 270Ω typ - Ensures minimal voltage drop and gain error in precision instrumentation paths. |
| Channel Leakage (ID(OFF)) | ±5nA max at +25°C - Enables accurate DC-coupled measurements in high-impedance sensor interfaces. |
| Switching Time (ttransition) | 0.6µs typ - Allows multiplexing of signals up to ~1.5MHz without significant settling distortion. |
| Supply Range | ±4.5V to ±18V - Permits direct integration into industrial ±12V or ±15V power domains without level-shifting. |
| Off-Isolation (OIRR) | 68dB at 500kHz - Suppresses crosstalk between inactive channels in multi-sensor data loggers. |
| Enable Timing (tON(EN)) | 1µs typ - Enables synchronized channel activation in time-critical control loops. |
Pinout & Package
Package: 28-pin Wide SO (W28-5), RoHS-compliant, surface-mount, 15.4mm × 7.6mm body, 1.27mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 27 | V+, V− | Positive and negative analog supply rails - Must be decoupled locally; define full analog signal swing. |
| 2, 3, 13, 14, 23 | N.C. | No internal connection - Leave unconnected; no PCB trace or thermal pad required. |
| 4–11, 19–26 | S1b–S8b, S1a–S8a | Differential analog I/O channels - Paired terminals (e.g., S1a/S1b) form one differential switch path. |
| 12 | GND | Analog ground reference - Connect directly to system AGND plane; isolate from digital ground. |
| 15–18 | A2, A1, A0, EN | Address and enable logic inputs - TTL/CMOS compatible; EN must be ≥2.4V to activate switching matrix. |
| 28 | Da | Differential output terminal a - Used with Db (Pin 2) to deliver selected differential pair to downstream circuitry. |
| 2 | Db | Differential output terminal b - Complementary output to Da; both required for differential signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 0.2µs minimum open interval prevents momentary shorting between channels during address changes. |
| Latch-up proof construction | Immune to destructive latch-up even when analog inputs remain active while supplies are off (per JEDEC JESD78). |
| Symmetrical bidirectional operation | Identical on-resistance and leakage performance regardless of signal flow direction - supports true analog mux/demux use. |
| Drop-in replacement capability | Pins, timing, and logic behavior match Intersil IH6216 and Harris HI507 - enables legacy design refresh without layout change. |
| Low power consumption | 0.13mA I+ and –0.15mA I− at +25°C - reduces thermal load and extends battery life in portable DAQ equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HI507CDW | Same 28-pin Wide SO package; higher RDS(ON) (450Ω typ); no guaranteed latch-up immunity. | Legacy aerospace designs where qualification pedigree outweighs leakage or power specs. | Select HI507CDW only if existing qualification documentation mandates Harris heritage parts. |
| IH6216CJ | 28-pin Plastic DIP; 1µs slower switching; ±12V max supply; requires external charge pump for ±15V operation. | Through-hole prototyping or repair of older industrial controllers with DIP footprints. | Choose IH6216CJ when board rework constraints prohibit SOIC footprint adoption. |
Compared with HI507CDW and IH6216CJ, the DG507ACWI+ delivers lower on-resistance, superior off-isolation, and verified latch-up immunity - making it the preferred choice for new designs demanding precision, reliability, and surface-mount manufacturability.

FAQ
What is the maximum analog signal voltage range supported by the DG507ACWI+?
The DG507ACWI+ supports an analog signal range of ±15V when operated with V+ = +15V and V− = −15V. This rail-to-rail capability allows direct interfacing with standard industrial ±10V or ±15V sensor outputs without external level-shifting circuitry. Absolute maximum ratings permit V+ up to +44V and V− down to –44V, but functional analog range remains bounded by the supply rails.
Does the DG507ACWI+ require external pull-up resistors on its address inputs (A0–A3)?
No, the DG507ACWI+ does not require external pull-up resistors on A0–A3. Its address inputs are TTL and CMOS compatible, with specified input current ≤ ±0.002µA at logic-high (2.4V) and logic-low (0.8V) levels. The internal input structure provides sufficient noise margin and drive capability for direct connection to FPGA or microcontroller GPIO pins without additional biasing components.
Can the DG507ACWI+ be used in single-supply configurations?
Yes, the DG507ACWI+ can operate from a single supply (e.g., +12V and GND), but its analog signal range becomes asymmetric: 0V to V+ minus headroom. For example, with V+ = +12V and V− = GND, the usable analog range is approximately 0V to +10.5V. Full bidirectional performance and rail-to-rail operation require dual ± supplies as specified in the datasheet.
What is the purpose of the break-before-make interval in the DG507ACWI+?
The break-before-make interval (tOPEN = 0.2µs min) ensures that one channel is fully disconnected before the next channel connects. This prevents momentary short circuits between analog sources - critical in applications like multiplexed sensor arrays where sources may have different output impedances or floating grounds. It eliminates cross-talk transients and protects upstream signal conditioners from overload.
How does the DG507ACWI+ achieve latch-up immunity when power is removed?
The DG507ACWI+ achieves latch-up immunity through proprietary CMOS process design and internal protection structures that prevent parasitic SCR activation. As confirmed in the datasheet, it will not latch-up even when analog inputs remain present while V+ and V− are powered down - provided absolute maximum ratings (e.g., input voltage clamping diodes not exceeded) are observed. This enables safe "hot-swap" operation in modular test equipment.
