Original Press Release:

Fairchild Semiconductor Introduces the Industry's First 4-Bit, Low-Voltage Dual-Supply Voltage Translator with Independent-Direction Controls

The FXL4TD245 provides design flexibility and reduces board space in computing, communications, industrial and ultra-portable applications

San Jose, California - July 31, 2007 - Fairchild Semiconductor (NYSE: FCS) announces the FXL4TD245, the industry's first 4-bit, low-voltage dual-supply voltage translator with independent-direction controls. This unique control feature increases design flexibility by allowing designers to control the direction of each bit individually compared to typical configurations that control the direction of bi-directional voltage translators in groups of four, eight or sixteen bits. The FXL4TD245's wide voltage range of 1.1V to 3.6V simplifies designs and accommodates the voltage requirements of a variety of consumer and industrial applications. In addition, the FXL4TD245's ultra-compact (2.5mm x 3.5mm) DQFN package provides 65 percent board space savings versus TSSOP packaging, making it ideal for space-constrained ultra-portable, computing and consumer applications.

"Fairchild's FXL4TD245 is the first translator to allow designers to choose the configuration that makes sense for their specific design rather than being limited by the translator's architecture," said Gary O'Donnell, Fairchild's technical marketing manager for Logic Products. "This one-of-a-kind independent-direction control feature allows this translator to be configured for a wide array of designs, giving designers a level of flexibility unattainable by using previous solutions."

The FXL4TD245 is fully configurable: The A port tracks the level of the VCCA supply and the B port tracks the level of the VCCB supply. Both supplies are independent, allowing designers to select the translation levels and set the high side or low side according to their specifications. Other translator solutions force designers to use a preset high side or low side and to determine what the voltage needs to be.

Key advantages of the FXL4TD245 include:
Simplified design and design flexibility:
Independent-direction control for each bit.
Bi-directional interface between any two levels from 1.1V to 3.6V.
Fully configurable: Inputs track VCC level.
Minimal board space requirements:
Ultra-compact 16-terminal DQFN packaging.

Fairchild Semiconductor's growing FXL portfolio of logic translators offers designers a range of device options to better optimize their specific applications. For more information about these products, please go to Fairchild's logic-level translator webpage at: fairchildsemi.com/translator.

The FXL4TD245 utilizes lead-free (Pb-free) terminals and has been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. All Fairchild products are designed to meet the requirements of the European Union Directive on the restriction of the use of certain hazardous substances (RoHS).
