The ISL83384E is a ±15kV ESD protected RS-232 transmitter/receiver, with a power supply voltage range of +3V to +5.5V, a current consumption of 1 microamp, and a data transmission rate of 250Kbps. This product is suitable for low power applications such as PDAs, palmtops, and notebook computers, and it features small size, low power consumption, and good compatibility.
The Intersil ISL83384E RS‑232 transceiver is designed for battery‑powered, handheld and portable equipment such as PDAs, palmtops, notebooks and mobile phones. It features on‑chip charge pumps, a single‑pin power‑down function, and requires only four 0.1 µF external capacitors, enabling a very small footprint and low standby current.
The device meets EIA/TIA‑232 and V.28/V.24 specifications, offers +15 kV ESD protection on its RS‑232 pins, and operates over a wide supply range of +3 V to +5.5 V. It includes separate transmitter and receiver sections, each with built‑in hysteresis for improved noise immunity.
| Supply Voltage Range | +3 V to +5.5 V |
|---|---|
| Minimum Data Rate | 250 kbps |
| Power‑down Supply Current | < 1 pA |
| ESD Protection (RS‑232 pins) | +15 kV |
| Maximum Junction Temperature | 150 °C |
The SHDN pin disables all transmitters and receivers and shuts down the on‑chip charge pump, placing the device in a low‑power mode.
The device guarantees a minimum data rate of 250 kbps under worst‑case load conditions.
The RS‑232 pins are protected against up to +15 kV ESD events.
