Nexperia shrinks logic packaging for smaller designs
Smallest and thinnest standard logic DHXQFN packages for logic from Nexperia have 14, 16, 20 and 24 pins on a 0.4mm pitch

Nexperia has launched a series of logic packages that it says is the smallest and thinnest in the world.

The 16 pin DHXQFN package is 45 percent smaller than the industry-standard DQFN16 leadless device, saving 25 percent in PCB area. Measuring just 2 mm x 2 mm (14 pin), 2 mm x 2.4 mm (16 pin), 2 mm x 3.2 mm (20 pin) and 2 mm x 4 mm (24 pin), the 0.4 mm pitch DHXQFN packages are only 0.45 mm high.

The parts in the new package include larger logic funcitons such as hex inverting Schmitt-triggers, 8-bit SIPO shift registers with output latches, 4bit dual supply translating transceivers, octal buffer/line drivers and bus transceivers as well as 8bit dual supply translating transceivers.

“Previously, incorporating large logic functions into a system with a small form factor was unthinkable,” said Ashish Jha, Nexperia’s product manager. “However, our new DHXQFN package enables complex functions such as 74HC595 shift registers to fit into space-sensitive applications like smartwatches, mobile devices and internet connected industrial devices.”

The small footprint of DHXQFN package enables devices to be placed closer to the bypass capacitor, providing an advantage in designs with limited board space for glue logic parts. This also boots performance in high frequency applications since the traces between logic device and capacitor are shorter.
