Product details
Overview
DG418CJ+ from Maxim Integrated is a precision CMOS single-pole/single-throw (SPST) analog switch with normally open configuration, 35Ω max on-resistance, <5nA off-leakage at +85°C, and 2000V ESD tolerance. It operates from ±4.5V to ±20V bipolar or +10V to +30V single supply and is used in battery-operated systems, test equipment, and audio signal routing where rail-to-rail signal handling and low charge injection (10pC max) are critical.
For engineers reviewing the DG418CJ+ datasheet, DG418CJ+ pinout, DG418CJ+ application, or DG418CJ+ equivalent, this page delivers verified electrical parameters, package mapping to 8-pin plastic DIP, truth-table–confirmed logic behavior, and two validated alternative parts for SPST analog switching in industrial and communications designs.
Technical Context
The DG418CJ+ implements a silicon-gate CMOS transmission gate architecture optimized for bidirectional analog conduction with guaranteed on-resistance matching (3Ω max) and flatness (4Ω max) under bipolar supply operation. Its TTL/CMOS-compatible control input drives an internal level-shifter referenced to VL, enabling reliable switching across its full ±15.5V analog signal range.
Switching performance is characterized by tON < 175ns and tOFF < 145ns at ±15V supplies, with break-before-make timing absent (SPST topology). Charge injection is tightly controlled at ≤10pC, and off-isolation exceeds 68dB at 1MHz - critical for sample-and-hold and multiplexed data acquisition circuits requiring minimal signal corruption.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(ON)) | 35Ω max at +25°C; ensures minimal voltage drop and gain error in precision signal paths |
| On-Resistance Match | 3Ω max between channels; enables matched gain/attenuation in differential or dual-path circuits |
| Charge Injection | 10pC max; limits voltage glitch on hold capacitors in sample-and-hold applications |
| Off-Leakage Current | <5nA at +85°C; preserves capacitor charge integrity over temperature in low-power systems |
| Supply Range | ±4.5V to ±20V bipolar or +10V to +30V single; supports wide dynamic range signal conditioning |
| ESD Tolerance | 2000V min per Method 3015.7; enhances robustness during board handling and system integration |
| Switching Time (tON/tOFF) | <175ns / <145ns; enables high-speed multiplexing up to ~2MHz without significant settling delay |
Pinout & Package
Package: 8-pin plastic DIP (0.300" width), JEDEC MS-001, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Analog Drain (D) | Switch output terminal; connects to load or downstream circuitry; bidirectional conduction path |
| 2 | No Internal Connection (N.C.) | Unbonded pad; must remain unconnected to avoid parasitic coupling or mechanical stress |
| 3 | GND | Logic ground reference; decoupling capacitor required near pin for stable digital interface |
| 4 | V+ | Analog positive supply; sets upper rail of signal range; must be ≥|V−| for symmetric operation |
| 5 | VL | Logic supply input; tied to +5V for TTL compatibility or to V+ for CMOS-level inputs |
| 6 | IN | Control input; active-high logic; opens switch when high (DG418 is NO configuration) |
| 7 | V− | Analog negative supply; sets lower rail; determines minimum signal swing and leakage behavior |
| 8 | S | Analog Source (input); normally open terminal; connects to signal source when IN = high |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping, enabling full-supply-range instrumentation interfaces |
| Guaranteed RFLAT(ON) | 4Ω max variation across signal range ensures consistent gain/attenuation in precision amplifiers and filters |
| TTL/CMOS logic compatibility | Accepts standard 0.8V/2.4V thresholds with VL = +5V, simplifying integration with microcontrollers and FPGAs |
| Low power consumption | 35µW max total supply current enables use in always-on battery-powered measurement nodes |
| Bidirectional conduction | Identical on-resistance regardless of signal direction, essential for AC-coupled and symmetrical signal paths |
Applications
| Sample-and-Hold Circuits | Test Equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRZ | Higher on-resistance (4.7Ω typ), wider supply range (±5V to ±22V), but requires external level-shifter for TTL logic | Better suited for high-precision, low-distortion audio where on-resistance flatness is less critical than absolute value | Select ADG1419BRZ only if supply flexibility and lower RDS(ON) outweigh need for integrated logic-level translation |
| TS5A23157DCUR | Lower voltage rating (+5.5V max), higher off-leakage (>100nA at +85°C), but smaller 6-pin SC70 package | Targeted at space-constrained consumer electronics, not industrial test or battery-backed systems | Choose TS5A23157DCUR only for cost-sensitive, low-voltage, high-volume applications where leakage and ESD specs are relaxed |
Compared with DG418CJ+, ADG1419BRZ offers superior on-resistance but lacks integrated TTL compatibility, while TS5A23157DCUR sacrifices voltage range and leakage performance for footprint reduction - making DG418CJ+ the optimal choice for rugged, wide-supply, precision analog routing.

FAQ
What is the maximum analog signal range supported by DG418CJ+?
The DG418CJ+ supports an analog signal range from V− to V+, with guaranteed operation up to ±15.5V when V+ = +16.5V and V− = −16.5V. This rail-to-rail capability allows full utilization of the supply rails in both bipolar and single-supply configurations, making DG418CJ+ suitable for high-dynamic-range instrumentation where signal headroom is critical.
Does DG418CJ+ require external level-shifting for TTL logic inputs?
No, DG418CJ+ does not require external level-shifting for TTL logic inputs. When VL is connected to +5V, the IN pin accepts standard TTL thresholds (0.8V low, 2.4V high), and the internal level-shifter ensures proper gate drive across the full analog supply range. This integrated logic interface eliminates external components and simplifies design around DG418CJ+ in mixed-signal systems.
What is the guaranteed on-resistance match specification for DG418CJ+?
The DG418CJ+ guarantees on-resistance match of 3Ω maximum between channels under bipolar supply operation. This parameter is explicitly tested and specified in the datasheet for the DG417/DG418/DG419 family, ensuring predictable gain tracking in dual-path or differential configurations where DG418CJ+ is deployed as one half of a matched pair.
Can DG418CJ+ operate from a single +12V supply?
Yes, DG418CJ+ can operate from a single +12V supply by connecting V− to ground (0V). In this configuration, the analog signal range is 0V to +12V, and all electrical characteristics-including on-resistance (40Ω max), leakage (<5nA at +85°C), and switching time-remain valid per the single-supply specifications table. DG418CJ+ maintains full functionality without modification in such setups.
Is DG418CJ+ pin-compatible with legacy DG418 variants?
Yes, DG418CJ+ is pin-compatible with other DG418 variants in the same package type, including DG418C/D and DG418DJ. The 8-pin DIP footprint, pin functions (IN, S, D, V+, V−, GND, VL, N.C.), and thermal/mounting dimensions are identical across all C-grade and D-grade DG418 parts, enabling direct replacement in existing designs without PCB changes.
