Recommended die attach Epoxy die attach is recommended. Minimum quantity of electrically conductive epoxy must be used, with a narrow fillet around the die after contact Recommended bonding Bonding pads of the product are covered with aluminium metallic layer. Wedge or ball bonding can be used. Aluminium wire has be used if the assembly process is up to 250°C. Otherwise the use of gold wire is possible. The ground bounding length should be as short as possible to optimize the use of the product. The bonder should be properly grounded. Note 1: Vdd1 is used to connect the output buffers (on Q/QB) and can be applied separately from Vdd.
