Fairchild places 50 logic functions into MicroPaks

Fairchild Semiconductor International has released 50 single-, dual- and triple-input logic functions in its 1.45-by-1mm MicroPak chip-scale package, which is 65 percent smaller than an SC70.

Besides single-gate logic, 6-terminal MicroPak packages can accommodate more complex dual- and triple-input logic functions, including decoders, multiplexers, flip-flops, analog switches, and configurable logic. Performance levels include the TinyLogic High-Speed (HS and HST) and Ultra High-Speed (UHS) families.

All 50 functions are available in production volumes. In 1,000-piece quantities, a two-input AND gate (NC7SZ08-L6) is 16 cents and a three-state buffer (NC7SZ125L6X) is 20 cents. Targets include cell phones, PDAs, MP3 players, digital cameras, notebooks and other portable products.

The package's 0.2-by-0.3mm contact pads assure strong joint integrity, while its 0.5mm pitch spacing is said to facilitate high yield at mounting and to ease manufacturing handling. The packages are lead-free and rated MSL-1.

"By providing a large tool box of logic devices in MicroPaks, we are helping manufacturers upgrade designs and add features quickly and economically," said logic-product manager Ken Murphy. The packages "conserve board space, minimize trace lengths and minimize redesign," he said.
