AS91L1006BU - 6-Port JTAG Gateway

General Description

The AS91L1006BU is a one to 6-port JTAG gateway.

It partitions a single JTAG chain into six separate chains.

These separate chains can be optionally configured to operate as a single chain.

www.DataSheet4U.com July 2004 AS91L1006BU 6-Port JTAG Gateway Description The AS91L1006BU is a one to 6-port JTAG gateway. It partitions a single JTAG chain into six separate chains. These separate chains can be optionally configured to operate as a single chain. The AS91L1006BU device is used to provide enhanced capabilities to the standard IEEE1149.1. It enables the IEEE1149.1 interface to be used in a true Multi-Drop environment without any additional signals. This Multi-Drop capability enables the standard IEEE1149.1 interface to be used not just for stand alone PCB (Printed Circuit Board) testing, but also for complete system testing including all PCBs within a system back plane environment.
