description
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. Thepinoutmatchestheflow-throughdesignoftheSN75C1406toreducetheboardspacerequired
and to 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 TIA/EIA-232-F and ITU (formerly CCITT) V.28 standards.
These standards are for data interchange between a host computer and peripheral at signaling rates up to
20 kbit/s. The switching speeds of the TL145406 are fast enough to support rates up to 120 kbit/s with lower
capacitive loads (shorter cables). Interoperability at the higher signaling rates cannot be assured unless the
designerhasdesigncontrolofthecableandoftheinterfacecircuitsatbothends. Forinteroperabilityatsignaling
rates to 120 kbit/s, use of TIA/EIA-423-B (ITU V.10) and TIA/EIA-422-B (ITU V.11) standards is recommended.
The TL145406 is characterized for operation from 0°C to 70°C.
