The ISL83220E is a 3.0V to 5.5V powered RS-232 transmitter/receiver that meets ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. Additionally, it provides ±15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs and receiver inputs (RS-232 pins).
The ISL83220E is a 3.0 V to 5.5 V powered RS‑232 transmitter/receiver that meets EIA/TIA‑232 specifications and provides up to +15 kV ESD protection on its I/O pins. It features a manual power‑down function, low standby current, and requires only four external 0.1 µF capacitors for its on‑chip charge pumps.
The document includes pinout tables, absolute maximum ratings, electrical and timing specifications, ESD performance data, and package dimensions for the 16‑lead TSSOP version. It also describes power‑down control via the SHDN pin and optional receiver enable (EN) pin for further current reduction.
| Supply Voltage Range | 3.0 V to 5.5 V |
|---|---|
| Minimum Data Rate | 250 kbps |
| ESD Protection (RS‑232 pins) | +15 kV |
| Package Type | TSSOP 16‑lead thin shrink small outline plastic package |
It operates from a single supply of 3.0 V to 5.5 V.
The RS‑232 pins are protected up to +15 kV ESD.
Driving the SHDN pin low shuts down the transmitters and on‑chip power supply, entering power‑down.
The device guarantees a minimum data rate of 250 kbps.
