SN74CB3Q3253: p2p solution with SN74CB3Q3253 but can change source current ability

Passive switches like this are bidirectional. If you want to use the B pins as inputs and the A pins as outputs, then you can use a digital multiplexer like the SN74HC153; its pinout indeed is identical to that of the SN74CB3Q3253.

Hi Frank,

All of our analog switches are passive, meaning that they don't source/sink current , they just allow current to pass through the device. 

Like Clemens noted, the SN74HC153 is p2p and is a digital multiplexer. This means its unidirectional and does act as a current source or sink depending on the output state. 

Is your customer looking for something like this?

If possible, could you share what they are exactly looking to achieve with this part?

Best,

Hi team,

we have checked it with the customer, they need device 1 input 4 ouput, but SN74HC153 is 4 input 1 output. Do we have more suggestions. Thanks.
