A new low-voltage 2bit logic-level translator from Fairchild Semiconductor combines a wide voltage range with ‘output enable’ (tristate) capability and ultracompact packaging. The FXL2T245L10X is ideal for use in digital circuits to translate from lower to higher logic levels or vice versa, especially 1.2, 1.5, 1.8, 2.5 and 3.3V. The translator’s 1.1 to 3.6V range provides a lower voltage threshold than most alternatives, allowing it to better accommodate the low voltage needs of ultraportable applications, including cellphones, digital cameras and notebooks.

Packaged in a space-efficient 10-terminal MicroPak, Fairchild’s FXL2T245L10X is especially useful for ‘transparently’ adding two additional bits to an existing bidirectional translation path, such as a higher-definition LCD or stand-alone 2bit translation solution for USB port data I/Os, including Memory Stick, and other memory modules.

‘The FXL2T245L10X represents Fairchild’s continuing commitment to provide designers with the flexibility to match microprocessor I/Os to a broad range of higher and lower voltage functions’, says Ken Murphy, Fairchild Marketing Manager for Logic Products.

‘As product features are added in ultraportable appliances, designers are increasingly utilising more logic devices to resolve the mix of operating voltages’.

‘Fairchild’s 1, 2, 4, 5, 8 and 16bit logic level translators in DQFN, BGA, and MicroPak provide solutions to such problems, while requiring the minimum amount of board space’.

Like other FXL series translators, the lead (Pb)-free FXL2T245L10X meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020B and is compliant with European Union requirements now in effect.
