Product details
Overview
DG413LDY from Vishay Siliconix is a precision monolithic quad SPST CMOS analog switch with two normally open (NO) and two normally closed (NC) channels, designed for high-speed, low-error switching of ±15 V analog signals in battery-powered test and data acquisition systems. It features 25 Ω on-resistance, 68 ns turn-on time, 0.35 µW ultra-low power dissipation, and 44 V supply rating.
For engineers reviewing the DG413LDY datasheet, DG413LDY pinout, DG413LDY application, or DG413LDY equivalent, key selection criteria include break-before-make timing (20 ns), channel-to-channel crosstalk (-88 dB), off-isolation (-91 dB), charge injection (22 pC), and compatibility with dual-supply (±15 V) or single-supply (12 V) operation.
Technical Context
The DG413LDY implements complementary MOSFET pairs per channel to enable bidirectional conduction with symmetrical on-resistance and low distortion. Its break-before-make architecture prevents signal shorting during channel transitions, critical for multiplexer and relay-replacement applications requiring signal integrity.
Control logic is TTL/CMOS-compatible with VL = 5 V reference; IN1/IN2 drive SW1/SW4 (NO), while IN3/IN4 drive SW2/SW3 (NC). The device uses Vishay's high-voltage silicon gate process with epitaxial layer latchup protection and operates across -40 °C to +85 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Higher RDS(on) (45 Ω), slower tON (120 ns), no break-before-make guarantee | Lower cost for non-critical multiplexing; unsuitable for glitch-sensitive sampling circuits | Select when budget constraints outweigh precision timing needs and ±15 V range is not required |
| ADG1414BRUZ | Lower RDS(on) (1.8 Ω), higher supply rating (±20 V), but larger 20-pin TSSOP package | Better performance in high-precision metrology; requires PCB redesign due to different footprint and pinout | Select when ultra-low on-resistance and enhanced voltage margin justify layout change and cost premium |
Compared with MAX4617ESE+ and ADG1414BRUZ, the DG413LDY uniquely balances 25 Ω on-resistance, 68 ns speed, and integrated break-before-make timing in a standard SOIC-16 package-making it optimal for space-constrained, battery-powered precision systems where signal integrity and power efficiency are co-prioritized.

FAQ
What is the operating temperature range for the DG413LDY?
The DG413LDY is rated for operation from -40 °C to +85 °C, matching the "D" temperature suffix in its ordering code. This range is validated per Vishay's specification tables and supports deployment in industrial environments, portable test gear, and outdoor instrumentation without thermal derating. The DG413LDY maintains specified RDS(on), tON, and leakage performance across this full range.
Does the DG413LDY support single-supply operation?
Yes, the DG413LDY supports single-supply operation with V+ = 12 V and V- = 0 V, delivering an analog signal range of 0 V to 12 V. In this configuration, RDS(on) increases to 49 Ω typical and tON extends to 95 ns, as confirmed in the unipolar supply specifications table. Logic interface remains 5 V compatible via VL pin.
How does the break-before-make function work in the DG413LDY?
The DG413LDY implements hardware-enforced break-before-make timing exclusively between its paired NO and NC switches (SW1/SW2 and SW3/SW4), with a guaranteed 20 ns minimum delay. This prevents simultaneous conduction during logic transitions, eliminating signal shorting in relay-replacement and fault-tolerant routing applications. The timing is intrinsic to the IC's internal control logic and requires no external circuitry.
What is the maximum analog input voltage the DG413LDY can handle?
The DG413LDY supports analog signals up to ±15 V when operated with dual supplies (V+ = +15 V, V- = -15 V), as specified in its analog signal range parameter. Absolute maximum ratings allow V+ to V- up to 44 V, but sustained analog signals must remain within the supply rails to avoid clamping by internal protection diodes and potential damage.
Is the DG413LDY RoHS compliant?
Yes, the DG413LDY is RoHS compliant with lead-free terminations, as indicated by the "-E3" suffix option in Vishay's ordering information and confirmed in the package documentation. The narrow SOIC package meets JEDEC MS-012 standards and carries no exemptions for lead content.
