Part Number: TMUX1109 Other Parts Discussed in Thread: TMUX7219 , I am using this 4-channel multiplexer to switch my UART connection to an MC upon insertion of a USB for firmware uploads. Previously I was using two distinct 1 channel multiplexers but decided…
Part Number: TMUX1109 I have a question about the TMUX1109.
If some kind of ESD event triggers the switch into a conducting state, will it stay in that conducting state?
I am referencing this documentation (TI white paper)
"Latch-Up is not a risk if the…
Part Number: TMUX1109 Hi,
designing an embedded Linux system with a of-the-shelf Linux module, we face lack of UART connections.
We need to communicate at 9600 baud with
- RF MCU
- BLE module
- Debug
- another RF module
Having only 2 UARTs, it's going…
Part Number: TMUX1109 Other Parts Discussed in Thread: TMUX1574 We are considering using the TMUX1109 for multiplexing various digital interface signals including I2C, SPI bus, I2S digital audio, SWD (for programming ARM microcontroller) and UART at 1…
Part Number: TMUX1109 Other Parts Discussed in Thread: TVS2701 We want to use TMUX1109 in a project and the TMUX has VS, VD max of VDD+0.5V. Is there any internal clamp-diodes on the input of the TMUX1109?
We have 6.8kohm in series with the input and…
Part Number: TMUX1109 Dear Team,
My customer found there has an inrush current pass to mosfet of TMUX1109 when power on.
They would like to know what would be the impact of this symptom.
The inrush current is over 30mA. But there is only continuous current…
Thanks for the detailed responses. The link you sent was excellent.
My application is for bipolar square waves between 0.1-10kHz, which are then rectified and lowpass filtered to DC.
My latest version MUXes one of four RG resistors using 1/2 of the T…
Part Number: TMUX1109 We are considering using the TMUX1109 with 1.8V supply. The ON resistance (Ron) goes up dramatically for 1.8V supply operation (40 Ohm at 25 C temp). The Ron is 4 Ohms max for 2.5V supply. Is there any typo about this on the datasheets…
Part Number: TMUX1109
Dear technical support team,
I have a question about appropriate supply voltage range and mux for small input signal.
For example, input voltage range is very small such as 10mV, then which supply voltage is better, ±2.5V(max range…
Part Number: TMUX1109
Dear Sirs
I'm going to use the TMUX1109 analog multiplexer but find the timing in the data sheet to be unclear. For example, what is the address stable time before applying the enable? What is the settling time of the switch …
