5 TMUXBQB-DYYEVM Setup
Figure 5-1. DUT Footprint U1
The TMUXBQB-DYYEVM 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 TMUX device to this location,
which will serve as the Device Under Test (DUT). Compatible devices include 16-pin parts with PW, BQB or DYY
package names.
The headers of the TMUXBQB-DYYEVM can be easily connected to a power rail using 2.54 mm shunts on
J1-J16, not included with the board. Connecting the shunt between pin 4 of the header and pin 3 (GND) to
connect the corresponding pin of U1 to GND. Alternatively, the pins of U1 can be shorted to VDD or VSS by
connecting between pin 4 of the header and pin 2 or pin 6 respectively.
Figure 4-2 and Table 4-1 includes
detailed descriptions of the connections on J1 through J16.
Figure 5-2. Signal Line Circuitry (3D)
As shown in Figure 5-2 and Figure 5-3 as R21 and R22 on the J5 (pin 5 of U1) signal line, the TMUXBQB-
DYYEVM includes 0 Ω series resistors (0805 package) on each signal line.
