description

The TUSB2046 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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
