DESCRIPTION/ORDERING INFORMATION

The MAX232E 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.
