SLLS185A - DECEMBER 1994 - REVISED MARCH 1995
The TL145406 is a bipolar device containing three independent drivers and receivers that are used to interface data terminal equipment (DTE) with data circuit-terminating equipment (DCE). The drivers and receivers of the TL145406 are similar to those of the SN75188 quadruple driver and SN75189A quadruple receiver, respectively. The pinout matches the flow-through design of the SN75C1406 to reduce the board space required and allow easy interconnection. The bipolar circuits and processing of the TL145406 provide a rugged low-cost solution for this function at the expense of quiescent power and external passive components relative to the SN75C1406.
The TL145406 complies with the requirements of the EIA/TIA 232-E and ITU (formerly CCITT) V.28 standards. These standards are for data interchange between a host computer and peripheral at signalling rates up to 20 kbits/s. The switching speeds of the TL145406 are fast enough to support rates up to 120 kbits/s with lower capacitive loads (shorter cables). Interoperabilityat the higher signalling rates cannot be assured unless the designer has design control of the cable and the interface circuits at both ends. For interoperability at signalling rates to 120 kbits/s, use of EIA/TIA-423-B (ITU V.10) and EIA/TIA-422-B (ITU V.11) standards are recommended.
The TL145406 is characterized for operation from 0°C to 70°C.
