TL145406DWG4

RS-232接口集成电路 Tr RS-232 Drivers Receivers

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.
