Dual-output buffer for DDR SDRAM modules
Fairchild Semiconductor has introduced a dual-output registered buffer for 184-pin, 2.5V PC200/PC266, 72bit-wide registered double data rate (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.
In addition, they are well suited for low-voltage inrush current control in telecomms/industrial equipment.
FPF200X devices' wide input voltage range of 1.8 to 5.5V is ideal for today's electronics with battery operating voltages that can dip as low as 1.8V.
Each IntelliMax load switch replaces multiple active and passive components used in traditional analogue IC control functions and MOSFET power switch approaches.

PLL clock drivers target high-speed clocking
Two low voltage PLL clock drivers designed for use in high-speed memory clocking applications are now available from Fairchild Semiconductor.
In addition to saving circuit board area, the IntelliMax integrated approach speeds time to market by providing the designer with a choice of products that enables total flexibility in implementing hardware or software control techniques.
The reduced number of components required to accomplish this also leads to substantial inventory and assembly cost-savings.
The FPF200X series offers a range of device options, providing designers with the flexibility to address a multitude of system architectures.
Each FPF200X load switch includes controlled switch turn-on, current-limiting with 50 or 100mA options, undervoltage lockout and thermal shutdown.
Also included are a flag for fault conditions with options for fault blanking; and auto-restart functions - all with 4kV ESD protection.
IntelliMax also features low-shutdown current (less than 1uA) to conserve battery life, and a fast current limit response time (3us for nominal overcurrent conditions, 20ns for hard short conditions) for safety/fault protection.
"The new FPF200X series of IntelliMax advanced load switches offer designers an off-the-shelf solution that greatly simplifies designs while delivering excellent power management, load-control and protection benefits", said Izak Bencuya, Chief Strategy Officer and Power Discrete Group Executive Vice President/general Manager for Fairchild Semiconductor.
"IntelliMax technology combines the best of low-voltage power semiconductors and analogue control circuitry with surface-mount packaging technology to optimise solutions for the latest ultraportable products".
"Our advanced FPF200X load switch products are the first in a series of single package, multifunction IntelliMax products".
These products are lead-free (Pb-free) and meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020B and are compliant with the European Union requirements that are now in effect.
