DG417L/DG418L/DG419L 35Ω, SPST/SPDT, +3V Logic-Compatible Analog Switches are precision CMOS analog switches from Maxim company, which features low on-resistance (RON = 35Ω), guaranteed RON matching between switches (3Ω max), and guaranteed RON flatness over the signal range (4Ω max).
The DG417L, DG418L, and DG419L are precision CMOS analog switches featuring low on‑resistance (R ON = 35 Ω) and guaranteed matching and flatness across channels. They operate with +3 V logic‑compatible digital inputs (VIL = 0.8 V, VIH = 2.0 V) and support both single‑supply (+9 V to +36 V) and dual‑supply (±4.5 V to ±20 V) configurations. Switching times are under 175 ns (turn‑on) and 185 ns (turn‑off), with off‑leakage currents below 5 nA at +85 °C.
The devices are offered in 8‑pin µMAX, 8‑pin SO, and 8‑pin plastic DIP packages and are rated for an operating temperature range of –40 °C to +85 °C. Typical applications include sample‑and‑hold circuits, communications systems, test equipment, and battery‑operated devices.
| On‑Resistance (R_ON) max | 35 Ω |
|---|---|
| Logic Input High Voltage (VIH) | 2.0 V |
| Logic Input Low Voltage (VIL) | 0.8 V |
| Supply Voltage Range (dual) | ±4.5 V to ±20 V |
| Supply Voltage Range (single) | +9 V to +36 V |
| Turn‑On Time (t_ON) | < 175 ns |

The switches accept +3 V logic with a low‑level threshold of 0.8 V and a high‑level threshold of 2.0 V.
They are offered in 8‑pin µMAX, 8‑pin SO, and 8‑pin plastic DIP packages.
The maximum on‑resistance is 35 Ω.
