Each receiver converts EIA-232 EIA-232 inputs to 5-V TTL/CMOS levels. These receivers have a typical threshold of 1.3 V and a typical hysteresis of 0.5 V, and can accept ± 30-V inputs. Each driver converts TTL/CMOS input levels into EIA-232 EIA-232 levels. The driver, receiver, and voltage-generator functions are available as cells in the Texas Instruments LinASICTM library. 1 T2IN R1OUT R2OUT 1 3 4 5 C1+ VCC C1­ 2VCC ­ 1.5 V C2+ ­2VCC + 1.5 V 2 V S+ 6 VS ­ C2­ 11 14 10 7 12 13 T1OUT T2OUT R1IN 8 9 0V R2IN 15 GND This symbol is in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12.
