Part Number: SN74CBT3257 Hi Team,
I just want to double check for customer's schematics.
One of the SN74CBT3257 were using 3 channel for SPI de-multiplexer, 1 channel for GPIO multiplexer in the same chip, I think it's ok, correct me if wrong.…
Part Number: SN74CBT3257 Other Parts Discussed in Thread: TS3USB3000 , TS3DV642 Hello,
i am using that multiplexer and makeing the pcb-layout, the question came up whether ther is another pin configuration available for that device.
The pin pattern In1A…
Part Number: SN74CBT3257 Hi Expert,
I saw the other vendor suggest SN74CBT3257 for the below application, but SN74CBT3257 datasheet shows the VIH min is 2.0V, it can't match AUX or DDC voltage level.
Do you have better suggestion for it? any reference…
Shu-cheng,
The SN74CBT3257PWR device is a bi-directional, passive FET switch, without any internal buffering. This simple switch does not have any drive current capability. The device can ideally be modeled as a 0 ohm wire that passes what ever signal…

The questions is a recommended treatment of unused xA and xBx pins of SN74CBT3257. Since SN74CBT3257 is an analog switch and those pins are bidirectional actually, I’d like to confirm…
Part Number: SN74CB3Q3257 Other Parts Discussed in Thread: SN74CBT3257 Hi,
As subject, could the device support both SPI and I3C? And what's the different between SN74CB3Q3257 and SN74CBT3257 Thanks.
This family's data sheets designate one side of each switch as an "input" and the other side as the "output". I understand (I think) the clamping action that limits the "output" to Vcc-1V. What's unclear to me is whether the input and output roles can…
Hi Kygo,
There are several alternative P2P parts I can suggest here. See below for list:
1) TMUX1574
2) SN74CBT3257
These two would act as your best bet as far as pin to pin replacements go.
Let me know if you have any questions on these!
Thanks!

Part Number: SN74AUC2G53 Other Parts Discussed in Thread: TMUX1219 , SN74LVC1G3157 , SN74CBT3257 Hi, Team,
We are considering using SN74AUC2G53 in a 3.3V system. As the recommended Vcc is 2.7V max , but the Absolute Maximum Ratings is limited to 3.6V, how…
Part Number: SN74CBT3257C Other Parts Discussed in Thread: SN74CBT3257 Hi team. When my customer uses SN74CBT3257 as follows, the voltage drops by 0.8V. VCC : 5V, A : Output , B1 : 5V(Input) , B2 : GND(Input) Could you tell me why the voltage drop? It seems…
