RS232 Transceivers for Hand Held Computers
Withstand 10kV ESD -Design Note 64
Sean Gold
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.
В® Linear TechnologyвЂ™s LT 1237 addresses the above
requirements. The LT1237 is a complete RS232 port,
with three drivers, п¬Ѓve receivers and a regulated charge
pump. Supply current is typically 6mA, but the device can
be shut down with two separate logic controls. The driver
disable pin shuts off the charge pump and the drivers вЂ“
leaving all receivers active, ISUPPLY = 4mA. The ON/OFF
pin shuts down all circuitry except for one micropower
receiver, ISUPPLY = 60ОјA. The active receiver is useful
for detecting start-up signals. The LT1237 operates up
to 120kBaud and is fully compliant with all RS232 speciп¬Ѓcations. Connections to the RS232 cable are protected
with internal ESD structures that can withstand repetitive
В±10kV human body model ESD pulses. …
