DS3691 - (RS-422/RS-423) Line Drivers

General Description

The DS1691A/DS3691 are low power Schottky TTL line drivers designed to meet the requirements of EIA standards RS-422 and RS-423.

They feature 4 buffered outputs with high source and sink current capability with internal short circuit protection.

Key Features

  • n Dual RS-422 line driver with mode pin low, or quad RS-423 line driver with mode pin high n TRI-STATE outputs in RS-422 mode n Short circuit protection for both source and sink outputs n Outputs will not clamp line with power off or in TRI-STATE n 100Ω transmission line drive capability n Low ICC and IEE power consumption RS-422: ICC = 9 mA/driver typ RS-423: ICC = 4.5 mA/driver typ: I EE = 2.5 mA/driver typ n Low current PNP inputs compatible with TTL, MOS and CMOS n Pin compatible with AM26LS.

DS1691A/DS3691 (RS-422/RS-423) Line Drivers with TRI-STATE Outputs July 1998 DS1691A/DS3691 (RS-422/RS-423) Line Drivers with TRI-STATE® Outputs General Description The DS1691A/DS3691 are low power Schottky TTL line drivers designed to meet the requirements of EIA standards RS-422 and RS-423. They feature 4 buffered outputs with high source and sink current capability with internal short circuit protection. A mode control input provides a choice of operation either as 4 single-ended line drivers or 2 differential line drivers. A rise time control pin allows the use of an external capacitor to slow the rise time for suppression of near end crosstalk to other receivers in the cable.
