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.
Their high performance ensures superior system reliability and energy efficiency when compared with similar HVICs on the market.
Fairchild's HVICs are the optimal solution for driving MOSFETs and IGBTs in a wide array of consumer and industrial applications up to 600V.
These include inverter motor drives, switch-mode power supplies (SMPS) and electronic ballasts.

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.
"Fairchild's latest half-bridge gate drivers offer designers the flexibility to optimise board space and system performance according to their application's specifications", said HK Kim, Fairchild's Vice president, Power Conversion product line.
"The feature set of these high-performance HVICs includes 8-DIP, 8-SOP and 14-SOP packages and also options for shut down, dead-time control and short-circuit protection".
Fairchild's HVICs feature advanced level-shift circuitry for industry-leading, high-side driver operation with negative VS swings of up to -9.8V (at VBS = 15V).
This results in the devices' unique ability to eliminate an extra diode, unlike other HVICs on the market.
In addition, Fairchild's HVICs provide excellent noise immunity by utilising a common-mode dv/dt noise-cancelling circuit.
These devices boast the industry's lowest quiescent currents for extremely low power consumption, a particularly important feature in motor applications.
Exhibiting the market's lowest temperature dependency, achieved by optimising the internal circuit design, these HVICs deliver full functionality at either cold or hot ambient temperatures, which guarantees stable performance in a wide range of applications.
To further enhance efficiency, these HVICs feature a floating channel designed for bootstrap operation to +600V.
They also increase reliability by providing undervoltage lockout (UVLO) on both channels, and an 11-20V supply range for VCC.
These lead (Pb)-free devices meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020C and are compliant with European Union regulations now in effect.
When combined with Fairchild's advanced MOSFETs, IGBTs and small-signal discretes, Fairchild's half-bridge gate drivers offer designers a complete half-bridge solution.
