Part Number: SN74CB3Q3257 The application is to mux an SD Card interface between two different processors using SN74CB3Q3257RGYR. The max clock speed will run at 33MHz. Wondering what is the impact of running the high-speed clock/data through the mux…
Part Number: SN74CB3Q3257 Other Parts Discussed in Thread: TMUX136 Hi
My customer tends to adopt SN74CB3Q3257 for EMMC5.1 scenario which is bidirectional 400MHz. Please help with below questions.
1.Is SN74CB3Q3257 ok for this scenario?
2. Customer…
Joyce,
What are you wanting to connect to the switch. You should be able to use this switch without any external components unless it is required by other devices in the signal path.
I believe the best explanation I can think of on why that 50…
Part Number: SN74CB3Q3257 The datasheet does not specify this. In general, if the datasheet does not indicate that a thermal pad should be floating, is it safe to connect to a ground layer.
Thanks.
Part Number: SN74CB3Q3257 Hi, for S(select pin) of SN74CB3Q3257, do we have any spec for rising time and falling time of S(select pin)? Thanks!
The concern is that if it is ok when S(select pin) stays between Vil max and Vih min too long.
Regards…
Other Parts Discussed in Thread: SN74CB3Q3257 Hi Sir,
Sorry to bother you.
We would like use SN74CB3Q3257 to switching LED.
What is the max passing ( A to B) current. 50mA??64mA?? or 100mA??
If our application need short B1 and B2, I think should…
Part Number: SN74CB3Q3257 Dear engineer;
Could you please provide the information of Thermal Resistance values for theta Jc, theta Jb and the maximum Junction Temperature value?
Best regards

Other Parts Discussed in Thread: SN74CB3Q3257 Team,
in SN74CB3Q3257 datasheet, I found a description at section 9.2.1 that
"Inputs and outputs are overvoltage tolerant slowing them to go as high as 4.6 V at any valid VCC"
I see all of this…
Other Parts Discussed in Thread: SN74CB3Q3257 Hello, I have big problem with SN74CB3Q3257 IC. I decided to use it like a digital MUX. When I connect to pin1B1 data from my AD converter (300kHz) and I connect switching signal to pin S (3MHz) I get return…
