SCDS423A October 2020 – May 2024 TMUX1575
PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The TMUX1575 can be operated without any external components except for the supply decoupling capacitors. The TMUX1575 has internal weak pull-down resistors (6 MΩ) to GND so that it powers-on with the switches in a known state. All inputs signals passing through the switch must fall within the recommend operating conditions of the TMUX1575 including signal range and continuous current. For this design example, with a supply of 3.3V, the signals can range from 0V to 3.3V when the device is powered. This example can also utilize the Powered-off protection feature where the inputs can range from 0V to 3.6V when VDD = 0V. Due to the voltage range and high speed capability, the TMUX1575 example is suitable for use in SPI, JTAG, eMMC, and I2S applications.
