Figure 6-1. DUT Footprint U1
The TMUXRTJ-RRQEVM will not have any device connected at footprint U1, and there are not any devices
included with the EVM for this footprint. Attach any compatible Texas Instruments 20-pin TMUX device to this
location, which will serve as the Device Under Test (DUT). Compatible devices include parts with RTJ or RRQ
package names.
By default, the TMUXRTJ-RRQEVM will have 2.54 mm shunts on headers J1 through J20 connected such
that the pins of U1 are connected to GND. Remove these shunts from J1 through J20 as necessary if these
connections are not desired. Alternatively, the pins of U1 can be shorted to V
DD
or V
SS
by connecting between
pin 4 of the header and one of the other pins on the header.
