Description

The DS26900 is a JTAG signal multiplexer providing connectivity between one of three master ports and up to 18 (36 in cascade configuration) secondary ports. The device is fully configurable from any one of the three master ports. The DS26900 can automatically detect the presence JTAG devices on the secondary ports. The DS26900 can be used in multiple configurations including as a single device, two cascaded devices, or two redundant devices. All device control and configuration is accomplished through standard JTAG operations via the selected master port.
