The ISL83220E is a 3 V‑to‑5.5 V RS‑232 transceiver with ±15 kV ESD protection and 1 µA power‑down current.
The ISL83220E operates from a single +3 V to +5.5 V supply and guarantees a minimum data rate of 250 kbps while consuming only 1 µA in power‑down mode. It features on‑chip charge pumps, manual power‑down control, and full ESD protection on all RS‑232 pins.
The device is offered in a 16‑lead TSSOP package, requires four 0.1 µF external capacitors, and is compatible with 3.3 V, 5 V, and mixed‑voltage systems. Detailed electrical specifications, pin descriptions, and absolute maximum ratings are provided for design reference.
