description  
The TUSB2046A is a 3.3-V CMOS hub device that provides one upstream port and four downstream ports in  
compliance with the 1.1 Universal Serial Bus (USB) specification. Because this device is implemented with a  
digital state machine instead of a microcontroller, no firmware programming is required. Fully compliant USB  
transceiversareintegratedintotheASICforallupstreamanddownstreamports. Thedownstreamportssupport  
both full-speed and low-speed devices by automatically setting the slew rate according to the speed of the  
device attached to the ports. The configuration of the BUSPWR pin selects either the bus-powered or the  
self-powered mode.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
