Product details

Single 2:1 mux with wide supply tolerance

The SN74LVC2G157DCT3 is a single 2:1 data selector/multiplexer from the 74LVC family, packing one independent 2:1 circuit into an 8-pin SM8 package.

Output drive and temperature grade

Each output sinks or sources 32mA, enough to drive a standard logic input or a low-power LED indicator directly, though the total package dissipation at full drive across all outputs needs a quick thermal check against the board's copper area.

SM8 footprint and sourcing posture

Housed in the 8-LSSOP / 8-MSOP (0.110" width, 2.80mm wide) body, the SM8 package is a compact surface-mount profile suited for dense PCB layouts — the 0.65mm pin pitch is hand-solderable with care but reflow is the production method.

Frequently asked questions

What package does the SN74LVC2G157DCT3 use?

It comes in the SM8 package, which is an 8-lead LSSOP/MSOP body measuring 0.110" wide by 2.80mm wide. The mounting is surface-mount, suitable for reflow soldering.
