Hi Frank,
It sounds like you are asking if SN74CBTLV3253 can back-power the supply rail when VI or VI/O is greater than VCC. I found this tech article that provides more information on how to determine if a device is capable of back-powering . The article…
Hi Sandesh,
Thanks for your explanation!
About your sentence 'If the I2C line is corrupted, it will not allow switch selection in the beginning ', it well explained the TCA9545A problem that my customers met before. So TCA9545A may not be suitable…
Part Number: SN74CB3Q3251 Other Parts Discussed in Thread: SN74CB3Q3253 , e2e,
I'm looking for an 8:1 and 4:1 LVDS mux capable of handling 500MHz signaling speeds. I’ve found the below devices and they look appropriate, will these work at 500MHz?…

Do unused analog inputs need to be pulled to GND or VCC via resistor (fro SN74CB3Q3251 and SN74CB3Q3253)
If so is this required for
a) Device protection e.g.…
Louis,
What application are you using the CD4052B device? It may help other people on the forum if you post a schematic or diagram.
The CD4052 will have a higher series resistance with lower power supply voltage.
If you use the 5 V spec…
Part Number: SN74LV4052A Other Parts Discussed in Thread: SN74CB3Q3253 , CD4052B Tool/software: Code Composer Studio Dear TI Support Team,
My design contains an MSP430 MCU with one UART, I would like to communicate with external modules(BLE, 2G, GPS…
Hirotaka-san,
The pull-up resistors on the I2C bus should be at the level of your master and slave. If the SN74CBTLV3253 devices is used with VCC = 3.3 V and 5V signals are applied to it, it will violate the abs max rating in the datasheet.
If…
Part Number: DRV110 Other Parts Discussed in Thread: SN74CB3Q3253 Hi, Our plan is to set Ipeak and Ihold of the DRV110 with a SN74CB3Q3253 (Dual 1-of-4 FET Mux/Demux). This device is supplied with a 3.3V supply allowing switching voltage to be up to 5V…
Hi,
You are correct that that CPLD does not support the open drain protocol of I2C, so I2C should connect directly from C5509A to both codecs.
The Chip select (CS) pin of the AIC23 when used in 2-wire (I2C) mode, simply determines seventh bit in…
Hi Naveen,
A mux can be used to drive multiple steppers. Using the DRV8835 as an example, there are a few recommendations.
1) Use separate FETs to control VCC on each of the DRV8835. This will minimize power when not in use.
2) When not in use,…
