Overview
LTC1318 Single 5V RS232/RS422/AppleTalk® DCE Transceiver FEATURES s s s s DESCRIPTION The LTC®1318 is a single 5V, RS232/RS422 transceiver for connection to the DCE, or peripheral side of an interface link.
It includes an on-board charge pump to generate a ± 8V supply which allows true RS232 output swings.
The charge pump requires only four external 0.
1µF capacitors.
The LTC1318 includes two RS232 drivers, a differential RS422 driver, a dedicated RS232 receiver, and a pin selectable RS232/RS422 receiver which can receive either single-ended or differential signals.
The LTC1318 features driver outputs which can be taken to common-mode voltages outside the power supply rails without damage.
Additionally, the driver outputs assume a high impedance state when the power is shut off, preventing externally applied signals from feeding back into the power supplies.
The RS232 devices will operate at speeds up to 100kbaud.
The RS422 devices will operate up to 2Mbaud.
The LTC1318 is available in a 24-lead SO Wide package.
