The ISL54050 is a low ON-resistance, low voltage, bidirectional, dual single-pole/double-throw (SPDT) analog switch designed to operate from a single +1.65V to +4.5V supply.
The ISL54050 is a bidirectional dual single‑pole/double‑throw (SPDT) analog switch that operates from a single +1.65 V to +4.5 V supply. It offers ultra‑low ON‑resistance (≈0.29 Ω) and fast switching (ton ≈ 40 ns, torr ≈ 20 ns), making it suitable for battery‑powered portable equipment such as cell phones, laptops, and medical devices.
The datasheet details electrical characteristics, absolute maximum ratings, package dimensions (10‑lead UTQFN 1.8 mm × 1.4 mm × 0.5 mm), pinout, test circuits, and protection features. Ordering information, RoHS compliance, and recommended handling procedures are also included.
