Dual-output buffer for DDR SDRAM modules

Bus hold makes logic more predictable
Fairchild Semiconductor has made a number of additions to its LCX family, the logic industry standard for 3.3V applications.
Building on its reputation for innovation, Fairchild has enhanced its ALVC product family to offer designers devices both with and without bushold.
Fairchild's product line provides designers power savings critical to applications such as PDAs and notebooks, where even slight power savings is important.
Using a device without bushold saves about 500uA per I/O on a 16bit device; this represents up to 8mA of current.
In traditional applications, the bushold circuit technique holds an IC device input in its last known state - high or low - regardless of fluctuating line-voltage episodes.
The internal bushold circuitry eliminates the need for an external pull-up resistor.
However, the same circuitry also dissipates power even when it's not needed.
Fairchild's solutions allow designers to choose between utilising the bushold function for traditional designs, or increasing power savings by selecting ALVC devices without bushold.
Fairchild's family of ALVC products also addresses the confusion often encountered in logic procurement.
Due to the variety of names used to identify logic families within the industry, this announcement enables simplified identification and ordering.
