Product details
Overview
DG413CY from Maxim Integrated is a quad SPST analog switch with two normally closed (NC) and two normally open (NO) channels, designed for precision signal routing in bipolar or single-supply systems. It delivers 35Ω max on-resistance, <5nA off-leakage at +85°C, and 10pC max charge injection-enabling low-distortion sample-and-hold and audio signal routing in battery-operated test equipment.
For engineers reviewing the DG413CY datasheet, DG413CY pinout, DG413CY application, or DG413CY equivalent, key selection criteria include guaranteed on-resistance flatness (Δ4Ω), rail-to-rail analog signal handling (±15.5V), TTL/CMOS logic compatibility, and ESD tolerance of 2000V per Method 3015.7.
Technical Context
The DG413CY implements four independent SPST switches fabricated in a 44V silicon-gate process, supporting dual ±4.5V to ±20V or single +10V to +30V operation. Its internal architecture ensures symmetrical conduction in both directions and guarantees matched on-resistance (≤3Ω) between channels under bipolar supply conditions.
Switch control uses standard TTL/CMOS-compatible inputs referenced to VL (typically +5V), with break-before-make timing (25ns typ.) confirmed for DG413 variants. Off-isolation exceeds 68dB and crosstalk remains below 85dB at 1MHz, enabling high-fidelity signal separation in communication and guidance systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(ON)) | 45Ω max at ±15V - ensures minimal signal attenuation in precision analog paths |
| On-Resistance Flatness (ΔRDS(ON)) | Δ4Ω max over full analog range - maintains consistent gain/attenuation across input voltage swing |
| Charge Injection | 10pC max - limits voltage glitch on sampled capacitors in S/H circuits |
| Off-Leakage Current | <5nA at +85°C - preserves accuracy in high-impedance sensor interfaces |
| Turn-On / Turn-Off Time | 175ns / 140ns max - supports sub-microsecond switching in real-time signal routing |
| Analog Signal Range | ±15.5V with ±16.5V supplies - enables rail-to-rail operation without clipping |
| ESD Tolerance | 2000V min per Method 3015.7 - provides robust handling during board assembly and field use |
Pinout & Package
DG413CY is housed in a 16-pin narrow SOIC (Small Outline Integrated Circuit) package, 3.9mm wide, with standard JEDEC MO-153 footprint and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control input | Active-high logic controls channel state; IN1/IN4 drive NC switches, IN2/IN3 drive NO switches |
| D1–D4 | Analog drain terminal | High-impedance side of SPST switch; connects to signal source or load depending on configuration |
| S1–S4 | Analog source terminal | Low-impedance side tied to common reference; bidirectional conduction allows flexible signal path design |
| V+ | Positive supply rail | Bias for P-channel MOSFETs; must be ≥|V−| + 9V for full ±15.5V analog range |
| V− | Negative supply rail | Bias for N-channel MOSFETs; substrate connection requires V+ tie for latch-up immunity |
| GND | Logic ground reference | Return path for digital control current; isolated from analog signal ground in mixed-signal layouts |
| VL | Logic supply voltage | Set to +5V for TTL compatibility or to V+ for CMOS-level inputs; defines logic threshold |
Key Features
| Feature | Design Value |
|---|---|
| Two NC + Two NO configuration | Enables simultaneous signal enable/disable in differential or redundant paths without external logic |
| Guaranteed RDS(ON) match ≤3Ω | Reduces gain mismatch in multi-channel instrumentation amplifiers and ADC front-ends |
| Rail-to-rail analog signal handling | Supports full ±15.5V input swing with ±16.5V supplies-critical for military radio and guidance system interfaces |
| Low power consumption (35µW max) | Extends battery life in portable test equipment and heads-up displays |
| TTL/CMOS logic compatibility | Eliminates level-shifting circuitry when interfacing with microcontrollers and FPGAs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG413BRZ | 44V abs max rating; 35Ω RDS(ON); 15pC charge injection; operates down to −40°C | Higher leakage (>10nA at +85°C); lower ESD rating (1500V) | Preferred for extended temperature industrial designs where leakage tolerance is relaxed |
| TS5A3157DCKR | Single-supply only (+1.65V to +5.5V); 0.75Ω RDS(ON); 3pC charge injection; 8-pin SC70 | Not suitable for ±15V signal routing; lacks NC/NO flexibility | Optimal for low-voltage portable audio where size and on-resistance dominate |
Compared with DG413CY, ADG413BRZ offers wider temperature support but trades off leakage and ESD robustness, while TS5A3157DCKR excels in low-voltage efficiency but cannot replace DG413CY in high-voltage bipolar signal paths.

FAQ
What is the maximum analog signal voltage range supported by DG413CY?
DG413CY supports an analog signal range of ±15.5V when operated with ±16.5V supplies. This rail-to-rail capability is achieved using its 44V silicon-gate process and internal level-shifting architecture. The device maintains specified performance across this full range, including guaranteed on-resistance flatness (Δ4Ω) and low charge injection (10pC max), making DG413CY suitable for high-fidelity signal routing in test and military applications.
Does DG413CY require separate logic and analog supply rails?
Yes, DG413CY requires three supply connections: V+ (positive analog), V− (negative analog), and VL (logic supply). VL must be set to +5V for TTL compatibility or tied to V+ for CMOS-level inputs. This separation ensures noise isolation between digital control and analog signal paths. The DG413CY datasheet specifies that improper VL biasing directly impacts switching thresholds and may cause erratic channel behavior-so correct VL configuration is essential for reliable DG413CY operation.
How does the two-NC/two-NO configuration of DG413CY differ from DG411CY and DG412CY?
DG413CY integrates two normally closed (IN1/IN4) and two normally open (IN2/IN3) SPST switches in one 16-pin SOIC package. In contrast, DG411CY contains four NC switches and DG412CY contains four NO switches. This hybrid topology enables unique functions such as simultaneous enable/disable of complementary signal paths-e.g., muting an audio output while activating a bypass loop-without adding external logic. The DG413CY pinout and truth table confirm distinct control mapping not shared by DG411CY or DG412CY.
Can DG413CY operate from a single +12V supply?
Yes, DG413CY supports single-supply operation from +10V to +30V, with V− connected to ground. At +12V, it delivers 100Ω typical on-resistance and maintains full rail-to-rail analog handling (0V to +12V). However, dynamic parameters shift: turn-on time increases to 250ns max and off-leakage rises slightly versus bipolar operation. The DG413CY electrical characteristics table explicitly lists single-supply test conditions (V+ = 12V, V− = 0V), confirming validated performance for battery-powered systems where dual supplies are impractical.
Is DG413CY pin-compatible with older industry-standard DG413 variants?
Yes, DG413CY is a plug-in upgrade for legacy DG413 devices, retaining identical 16-pin narrow SOIC pinout, logic interface, and functional diagram. Key improvements-including 3Ω max on-resistance matching, <5nA off-leakage at +85°C, and 2000V ESD rating-are implemented without altering pin assignments or timing behavior. The DG413CY datasheet explicitly states "Plug-In Upgrade for Industry-Standard DG411/DG412/DG413," confirming backward compatibility for drop-in replacement in existing PCB layouts.
