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.
