intersil ISL83387E Manual
Update: 30 September, 2023
The ISL83387E is an Intersil-developed RS-232 transceiver that operates from 3.0V to 5.5V and meets EIA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. It also provides ±15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs and receiver inputs (RS-232 pins). Target applications are PDAs, Palmtops, and notebook and laptop computers where low operational, and even lower standby power consumption is critical. Efficient on-chip charge pumps, coupled with manual and enhanced automatic powerdown functions, reduce the standby supply current to a 1µA trickle. TSSOP packaging, and the use of small, low value capacitors also ensure board space savings. Data rates greater than 250kbps are guaranteed at worst case load conditions. The ISL83387E features a VL pin that adjusts the logic pin output levels and input thresholds to values compatible with the VCC powering the external logic (e.g., a UART). This device includes an enhanced automatic powerdown function which powers down the on-chip power-supply and driver circuits. This occurs when all receiver and transmitter inputs detect no signal transitions for a period of 30 seconds. It power back up, automatically, whenever it senses a transition on any transmitter or receiver input. Table 1 summarizes the features of the ISL83387E, while A section provides more details.
