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. The pinout matches the flow-through design of the SN75C1406 to reduce the board space required

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

designer has design control of the cable and of the interface circuits at both ends. For interoperability at signaling

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.
