Product details

The Texas Instruments SN74LV157APW is a 4 x 2:1 multiplexer from the 74LV logic family. It selects one of two 4-bit data sources based on a single select input, making it a straightforward choice for data routing in mixed-voltage systems.

Package and field-swap reality

Housed in a 16-TSSOP (4.40 mm wide body), this is a surface-mount part. No socket option exists for this footprint, so swapping it on site means hot air or a fine-tipped iron — not a field-kit job unless you carry a hot-air station. MSL is not listed, but a 24-hour bake at 125°C before reflow is cheap insurance if the seal is broken.

The 74LV series is a mature logic family, but TI continues to support it.

Frequently asked questions

Is the SN74LV157APW RoHS compliant?

Yes, it is ROHS3 Compliant per the lifecycle record.

What is the function of the SN74LV157APW?

It is a 4 x 2:1 multiplexer — it selects one of two 4-bit data inputs and routes it to the output based on a single select line.

What is the difference between the SN74LV157APW and the 74LV157A?

The SN74LV157APW is a specific TI order code in the 74LV family; the 74LV157A is the generic base part number. The 'PW' suffix indicates the 16-TSSOP package and tube packaging. Functionally they are the same 4 x 2:1 multiplexer, but the 'APW' variant is the TI-specific ordering code for this package and temperature grade.
