The QS3253QG8 is a Renesas multiplexer/demultiplexer with two independent 4:1 circuits — each selects one of four inputs to a common output, or routes a single input to one of four outputs depending on direction.
Pin 1 is marked by a chamfer on the top-left corner; the orientation mark is clear enough that you won't flip it during hand assembly.
The QS3253QG8 is a 2 x 4:1 multiplexer/demultiplexer, while the QS3244QG is a 4 x 1:1 bus switch. The circuit configuration and function differ — the QS3253QG8 routes one of four signals per channel, whereas the QS3244QG passes four independent signals straight through. They are not pin-compatible drops.
The QS3253QG8 is RoHS3 compliant.
