CMOS Logic Packages Are Getting Smaller

The Bus Switch, 74VHC, 74VHCT, 74LCX, and 74VCX are the first logic product families to offer what's claimed as the world's smallest and thinnest 16-pin and 20-pin CMOS logic packaging. The 16-pin and 20-pin packages boast a footprint that's 30% smaller than similar packages such as TVSOPs and TSSOPs. The new package makes for more compact and lighter portable products, such as notebook and sub-notebook PCs, PDAs, cell phones, other handheld products and LCDs. The thin packaging measures 3 mm x 4 mm x 1 mm for the US16 and 3 mm x 5 mm x 1mm for the US20. Both feature a 0.5-mm pin pitch supporting simpler assembly. They're supplied on an embossed tape-and-reel with 2500 parts per reel.
