ISL84521, ISL84522, ISL84523 Low-Voltage, Single and Dual Supply, Quad SPST, Analog Switches
The Intersil ISL84521, ISL84522 and ISL84523 are CMOS quad analog switches available in single‑supply (+2 V to +12 V) or dual‑supply (+2 V to +6 V) configurations. They offer low on‑resistance, fast switching (45 ns turn‑on, 15 ns turn‑off) and ultra‑low leakage (1 nA max) for battery‑powered and high‑frequency applications.
The datasheet provides detailed electrical specifications, absolute maximum ratings, pin‑out diagrams, package dimensions (SOIC and TSSOP), test circuit examples, and recommended protection methods such as series resistors and over‑voltage diodes. It also includes application notes on supply sequencing, ESD protection, and high‑frequency performance.
| Supply Voltage Range | +2 V to +12 V (single) or +2 V to +6 V (dual) |
|---|---|
| Turn‑On Time (ton) | 45 ns |
| ESD Protection | ≥2000 V per MIL‑STD‑883 Method 3015.7 |
They can operate from a single +2 V to +12 V supply or from a dual +2 V to +6 V supply.
The typical turn‑on time is 45 ns.
They provide at least 2000 V ESD protection per MIL‑STD‑883 Method 3015.7.
