Product details
Overview
DG419DY from Vishay Siliconix is a precision SPDT CMOS analog switch optimized for bidirectional signal routing in ±15 V dual-supply or 12 V single-supply systems. It delivers 20 Ω on-resistance, 100 ns turn-on time, break-before-make switching, and <0.75 nA off-leakage at full temperature range - enabling high-fidelity signal integrity in battery-powered instrumentation and military radios.
For engineers reviewing the DG419DY datasheet, DG419DY pinout, DG419DY application, or DG419DY equivalent, key selection criteria include guaranteed break-before-make timing (13 ns typ.), ultra-low 35 nW power dissipation, ±15 V analog signal range, SOIC-8 package compatibility, and HVSG process–enabled latchup immunity.
Technical Context
The DG419DY implements a monolithic SPDT switch architecture using Vishay's high-voltage silicon gate (HVSG) process, supporting true bidirectional conduction with symmetrical on-resistance and matched off-capacitance (CS(off) = CD(off) = 8 pF). Its control logic accepts TTL/CMOS-compatible inputs (0.8 V low / 2.4 V high) and drives two independent source terminals (S1, S2) from a single drain (D).
Break-before-make operation is electrically guaranteed across –40 °C to +85 °C, with 13 ns typical delay between switch transitions. An epitaxial layer prevents latchup, and internal clamping diodes protect against overvoltage transients up to ±2 V beyond supply rails.

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4619ESE+ | Higher RDS(on) (45 Ω), lower supply rating (±20 V), no guaranteed break-before-make | Less suitable for precision instrumentation requiring <0.01% linearity; acceptable for general-purpose multiplexing | Select when cost sensitivity outweighs need for guaranteed transition timing and ultra-low on-resistance |
| ADG1419BRMZ | Lower leakage (±0.1 nA), higher bandwidth (170 MHz), but larger 10-lead MSOP package | Better for high-frequency RF switching; less optimal for space-constrained SOIC layouts | Prefer for wideband applications above 10 MHz where DG419DY's 100 ns switching becomes limiting |
Compared with MAX4619ESE+ and ADG1419BRMZ, the DG419DY uniquely balances guaranteed break-before-make timing, SOIC-8 compactness, ±15 V signal range, and 20 Ω on-resistance - making it optimal for legacy-compatible, high-accuracy, low-power analog routing where board real estate and DC precision are critical.

FAQ
What is the guaranteed break-before-make time for DG419DY?
The DG419DY guarantees a minimum break-before-make time delay of 5 ns at room temperature and 13 ns typical under standard test conditions (RL = 300 Ω, CL = 35 pF, VS1 = VS2 = ±10 V). This timing is electrically ensured across the full –40 °C to +85 °C operating range, preventing simultaneous conduction between S1 and S2 in all qualified units of DG419DY.
Can DG419DY operate from a single 12 V supply?
Yes, DG419DY supports single-supply operation at 12 V (V+ = 12 V, V− = 0 V), delivering an analog signal range of 0 V to 12 V. In this configuration, turn-on time increases slightly to 110 ns typ., on-resistance rises to 40 Ω typ., and break-before-make delay extends to 60 ns typ. - all values confirmed in the unipolar supply section of the DG419DY datasheet.
What is the maximum allowable analog signal voltage for DG419DY?
The DG419DY supports analog signals up to ±15 V when operated with dual supplies (V+ = +15 V, V− = −15 V), and up to 0–12 V with single supply (V+ = 12 V, V− = 0 V). Signals exceeding these ranges are clamped by internal diodes; forward diode current must be limited to 30 mA continuous or 100 mA pulsed (1 ms, 10% duty cycle) per Absolute Maximum Ratings.
Does DG419DY require external decoupling on VL pin?
Yes, the VL pin (logic supply) requires a local 0.1 µF ceramic capacitor to ground, placed as close as possible to the DG419DY package. This decoupling suppresses digital switching noise from coupling into the analog signal path via the internal level shifter, which is essential to maintain <0.75 nA off-leakage and prevent false switching in noisy environments.
Is DG419DY RoHS-compliant?
The DG419DY-E3 and DG419DY-T1-E3 variants are RoHS-compliant and lead-free, as indicated by the "E3" suffix per Vishay's ordering information table. The base part number DG419DY may refer to non-RoHS versions with leaded terminations; only DG419DY-E3 and DG419DY-T1-E3 meet current EU RoHS Directive 2011/65/EU requirements.
