Overview
DS36950 Quad Differential Bus Transceiver July 1998 DS36950 Quad Differential Bus Transceiver General Description The DS36950 is a low power, space-saving quad EIA-485 differential bus transceiver especially suited for high speed, parallel, multipoint, computer I/O bus applications.
A compact 20-pin surface mount PLCC package provides high transceiver integration and a very small PC board footprint.
Timing uncertainty across an interface using multiple devices, a typical problem in a parallel interface, is specified — minimum and maximum propagation delay times are guaranteed.
Six devices can implement a complete IPI master or slave interface.
Three transceivers in a package are pinned out for connection to a parallel databus.
The fourth transceiver, with the flexibility provided by its individual enables, can serve as a control bus transceiver.
Features n n n n n Pinout for IPI interface Compact 20-pin PLCC package Meets EIA-485 standard for multipoint bus transmission Greater than 60 mA source/sink Thermal Shutdown Protection Pinout and Logic Diagram DS010602-1 Order Number DS36950 See NS Package Number V20A DS010602-2 TRI-STATE ® is a registered trademark of National Semiconductor Corporation.
