Product details

Switch-detection interface in a 32-QFN package

The NXP MC34978AES is a specialized interface IC for multiple switch detection — think banked switch inputs on a control panel or automotive body module where you need to read a row of buttons or limit switches over a single serial link.

Package and board-fit details

Housed in a 32-VFQFN exposed-pad package (5x5 mm body, supplier device package 32-QFN-EP), the MC34978AES has a wettable flank option on the package terminals — this means the solder fillet climbs the side of the QFN, giving a visible joint after reflow that AOI can inspect, unlike a standard QFN where the joint is hidden under the body.

Lifecycle and compliance snapshot

RoHS3 compliant (2011/65/EU + 2015/863), with no exemptions claimed — no lead, mercury, cadmium, or phthalates above the threshold limits.
