Part Number: SN74CB3Q3257 hi All Customers are using SN74CB3Q3257 to design a SIM card selector switch.
Power needs to be transmitted together. The power current is about 50mA. Can the IO of SN74CB3Q3257 support such a large current? If not, do we have…
Part Number: SN74CB3Q3257 Other Parts Discussed in Thread: TMUX1574 , SN3257-Q1 Hi,
We are using the SN74CB3Q3257 (4 channels ,2:1, Multiplexer) in our application.
The supply voltage is 3.3V, so the Vs must >2V to control. But the Vs voltage from MCU…
Part Number: SN74CB3Q3257 In SN74CB3Q3257 datasheet that doesn't list "SEL" pin VIH and VIL.
Could you tell me the VIH & VIL specification in Vcc=3.3V design?
Part Number: SN74CB3Q3257 We are using SN74CB3Q3257 as aSPI Mux. The B side connected to BMC and CPLD and A side connected to Flash,.
Pin-14 (4B1) and Pin-13 (4B2) are shorted together and used for CS# driven by CPLD (Max10)
We see the logic low is offset…
Part Number: SN74CB3Q3257 Other Parts Discussed in Thread: SN3257-Q1 Hi Sir,
Did we have the automotive grade AEC Q100/Q200 for SN74CB3Q3257?
Or if we have other suggestion parts to customer please share to me.
Thanks,
George
Part Number: SN74CB3Q3257 Hi team,
My customer is using the IBIS model for the bus switch "sn74cb3q3257" in the HyperLynx program to simulate the signal integrity of our PCB Layout and for some reason I cannot configure the model as an output. It only…
Part Number: SN74CB3Q3257 Hello Guys,
Good day.
Our customer is using four SN74CB3Q3257PWG4 in their design. Pin 10 of the parts have been lifted and not connected to the PCB pad. He then measure the PCB pad to VCC and it is open. When he measure the lifted…
Part Number: SN74CB3Q3257 Hi Sir,
Could you please check what will happen if SN74CB3Q3257DGVR pin7 short to ground?
Will it result in system/board damage or burn out issue?
Thank you.
Hi Ambroise,
I have used the attached IBIS model for SI simulation in Allegro SI.
While importing this file. I got following model(please find in the 1st snapshot)
Here all the models are like input and in out, but what I required is a series model(input…
Part Number: SN74CB3Q3257 hi dear supporting team,
in customer's p/l, they recently found several failure cases on SN74CB3Q3257. they use PIN5,PIN6 and PIN7 for bi-directional I2C data write and read.
the phenomenon is the for failed chip:PIN7 output…
