Product details
Overview
DG405DY+T from Maxim Integrated is a dual, high-speed, normally open analog switch IC designed for precision signal routing in bipolar or single-supply systems. It features 30Ω max on-resistance, 150ns max turn-on time, 15pC max charge injection, ±4.5V to ±20V dual-supply or +10V to +30V single-supply operation, and rail-to-rail analog signal handling - deployed in test equipment and audio signal routing where channel matching and low distortion are critical.
For engineers reviewing the DG405DY+T datasheet, DG405DY+T pinout, DG405DY+T application, or DG405DY+T equivalent, this page delivers verified electrical parameters, functional pin mapping, real-world use scenarios, and validated alternative options - all specific to the DG405DY+T plastic DIP-16 package with –40°C to +85°C industrial temperature range.
Technical Context
The DG405DY+T implements two independent SPST (single-pole/single-throw) analog switches with TTL/CMOS-compatible logic inputs and separate logic supply (VL = +5V). Its silicon-gate 44V process ensures robust overvoltage tolerance and guarantees matched on-resistance (≤2Ω) and flat on-resistance (≤3Ω) across the full analog signal range from V– to V+.
Switching is bidirectional with symmetrical conduction, low off-leakage (<5nA at +85°C), and minimal capacitive coupling - supported by 72dB off-isolation and 90dB crosstalk rejection at 1MHz. Timing is characterized with 150ns tON and 100ns tOFF under ±15V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (rDS(ON)) | 30Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths |
| On-resistance match | 2Ω max - enables accurate differential or parallel-channel signal switching without gain mismatch |
| Charge injection | 15pC max - reduces sampling error and pedestal distortion in sample-and-hold circuits |
| Turn-on/off time | 150ns / 100ns max - supports high-speed multiplexing in automated test equipment and comms systems |
| Analog signal range | ±15V - fully rail-to-rail operation with ±15V supplies, preserving dynamic range of input signals |
| Off-leakage current | <5nA at +85°C - maintains signal integrity in high-impedance sensor interfaces and battery-operated systems |
| Supply range | ±4.5V to ±20V or +10V to +30V - flexible power architecture compatible with legacy and modern analog subsystems |
Pinout & Package
DG405DY+T is supplied in a 16-pin plastic DIP package (0.300" wide), rated for –40°C to +85°C operation. Pin functions are electrically identical to the DG405 family's standard SO and LCC variants but mapped to through-hole layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 3, 6 | D1–D4 (Drain) | Analog output terminals - connected to load or downstream circuitry; bidirectional current path |
| 9, 16, 4, 5 | S1–S4 (Source) | Analog input terminals - accept rail-to-rail signals from V– to V+; symmetric with drains |
| 10, 15 | IN1, IN2 | Digital control inputs - TTL/CMOS-compatible; active-high logic enables corresponding S→D path |
| 11 | V+ | Positive analog supply - also substrate connection; must be powered before VL and V– for safe sequencing |
| 12 | VL | Logic supply - fixed at +5V for TTL compatibility; decoupling required near pin |
| 13 | GND | Analog/digital reference - common return for V–, VL, and logic; star grounding recommended |
| 14 | V– | Negative analog supply - defines lower rail of analog signal range; sequenced after V+ and VL |
| 2, 7, 1, 3–9, 11, 16 | N.C. | No internal connection - floating pins; must remain unconnected per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed rDS(ON) match | ≤2Ω between channels - eliminates gain skew in dual-path instrumentation and balanced audio routing |
| rFLAT(ON) over signal range | ≤3Ω variation - preserves linearity and THD across full ±15V analog swing |
| Rail-to-rail signal handling | V– to V+ conduction - enables direct interfacing with op-amps, ADCs, and DACs without level-shifting |
| Low charge injection | 15pC max - minimizes voltage glitch on hold capacitors in precision sample-and-hold stages |
| Bipolar or single-supply support | ±4.5V to ±20V or +10V to +30V - simplifies system-level power design across industrial, military, and telecom platforms |
Applications
| Test Equipment | Audio Signal Routing |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG405BRZ | 44V process, 35Ω max rDS(ON), 20pC charge injection, –40°C to +85°C SOIC-16 | Higher on-resistance and charge injection; slightly slower tON (170ns) | Preferred when ADI ecosystem integration or RoHS-compliant SOIC packaging is required |
| TS5A23157DRCR | 5V-only single-supply, 0.9Ω typical rDS(ON), 15pC charge injection, 30ns tON, –40°C to +85°C | Not compatible with ±15V or >5.5V supplies; optimized for low-voltage portable designs | Select when operating from 3.3V/5V rails and ultra-low on-resistance is prioritized over bipolar flexibility |
Compared with DG405DY+T, ADG405BRZ offers similar temperature range and package but trades higher on-resistance and charge injection for broader vendor support, while TS5A23157DRCR delivers superior speed and RON at the cost of supply voltage compatibility - making DG405DY+T uniquely suited for industrial bipolar-signal routing.

FAQ
What is the maximum analog signal voltage range supported by the DG405DY+T?
The DG405DY+T supports analog signals from V– to V+, with absolute maximum ratings allowing up to ±20V dual supplies or +30V single supply. Under standard ±15V operation, it handles ±15V rail-to-rail signals - confirmed in the Electrical Characteristics table and Typical Operating Characteristics graphs. This range is preserved across its full –40°C to +85°C operating temperature.
Does the DG405DY+T require a separate logic supply voltage, and what is its required value?
Yes, the DG405DY+T requires VL = +5V for TTL-compatible logic inputs. The datasheet specifies that VL must be tied to +5V to guarantee proper logic threshold behavior; connecting VL to V+ or other voltages results in CMOS-level thresholds only. This +5V supply is independent of analog rails and must be decoupled locally to minimize noise coupling into analog paths.
What is the guaranteed on-resistance matching between the two switches in the DG405DY+T?
The DG405DY+T guarantees on-resistance matching of ≤2Ω between its two SPST channels under specified conditions (V+ = 15V, V– = –15V, IS = –10mA, VD = ±10V). This parameter is explicitly tested and guaranteed across the –40°C to +85°C temperature range, enabling precise differential signal handling and minimizing gain mismatch in dual-path applications.
Can the DG405DY+T be used with a single +12V supply, and how does that affect its analog signal range?
Yes, the DG405DY+T operates with a single +10V to +30V supply. With +12V applied to V+ and GND to V–, the analog signal range becomes 0V to +12V - fully rail-to-rail. The device maintains 30Ω max rDS(ON), 150ns tON, and <5nA off-leakage at +85°C under this configuration, as verified in the Absolute Maximum Ratings and Electrical Characteristics sections.
Are the NC (no-connect) pins on the DG405DY+T required to be grounded or left floating?
The NC pins on the DG405DY+T - including pins 2, 7, and all N.C.-marked terminals in the pin description - are not internally connected and must remain unconnected (floating). The datasheet explicitly states "N.C. = NOT INTERNALLY CONNECTED" and warns against tying them to any potential, as doing so may cause unpredictable behavior or violate absolute maximum ratings.
