Measuring just 2 mm x 2 mm (14 pins), 2 mm x 2.4 mm (16 pins), 2 mm x 3.2 mm (20 pins), and 2 mm x 4 mm (24 pins), the 0.4 mm pitch DHXQFN packages are only 0.45 mm high. The components include: hex invert Schmitt triggers; 8-bit SIPO shift registers with output latches; 4-bit dual-supply translation transceivers; octal buffer/line controllers; octal bus transceivers; and 8-bit dual-supply translation transceivers.
Ashish Jha, product manager at Nexperia, comments: “Nexperia has a history of over 50 years developing standard logic components, and we aspire to become the undisputed market leader within the next three years. These new packages are an example of the innovation we are bringing. Previously, incorporating large logic functions into a small form factor system was unthinkable. However, our new DHXQFN package allows complex functions like the 74HC595 shift registers to fit into space-sensitive applications such as smartwatches, mobile devices, and internet-connected industrial devices.”
Furthermore, the reduced size of the DHXQFN package allows devices to be placed closer to the shunt capacitor. This can be a significant advantage in designs with limited board space for glued logic components, and also results in improved performance in high-frequency applications, as the traces between the logic device and the capacitor are shorter.
