JAJSH40F March 2009 – December 2021 TS3A27518E
PRODUCTION DATA
The TS3A27518E can be properly operated without any external components. However, TI recommends connecting unused pins to the ground through a 50-Ω resistor to prevent signal reflections back into the device. TI also recommends that the digital control pins (INX) be pulled up to VCC or down to GND to avoid undesired switch positions that could result from the floating pin. Refer to the Enabling SPI-Based Flash Memory Expansion by Using Multiplexers application brief for more information on using switches and multiplexers for SPI protocol expansion.
For the RTW package, connect the thermal pad to ground.
