Battery-powered computers and instrumentation are often subjected to severe electrical stress which imposes some stringent demands on serial communication interfaces. As always, operating from a battery mandates minimal power consumption. Transceivers must also tolerate repetitive electrostatic discharge (ESD) pulses because cable connections frequently come in contact with humans and other charged bodies.

Linear Technology’s LT1237 addresses the above requirements. The LT1237 is a complete RS232 ...
