RS232 Transceivers circuits


Posted on Oct 18, 2012

Hand held computers are rapidly moving to 3V logic to save power. Yet higher voltage buses are still utilized elsewhere in the system for display driving and other functions. The LT1330 is functionally equivalent to the LT1237 but operates from 5V with a separate logic supply to interface directly with 3V logic.



Linear Technologys LT1237 addresses the above requirements. The LT1237 is a complete RS232 port, with three drivers, five receivers and a regulated charge pump. Supply current is typically 6mA, but the device can be shut down with two separate
