DESCRIPTION/ORDERING INFORMATION

The TRS232 is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/RS-232-F voltage

levels from a single 5-V supply. Each receiver converts TIA/RS-232-F inputs to 5-V TTL/CMOS levels. This

receiver has a typical threshold of 1.3 V, a typical hysteresis of 0.5 V, and can accept ±30-V inputs. Each driver

converts TTL/CMOS input levels into TIA/RS-232-F levels. The driver, receiver, and voltage-generator functions

are available as cells in the Texas Instruments LinASIC™ library.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

LinASIC is a trademark of Texas Instruments.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
