South Portland, Maine Fairchild Semiconductor's low-voltage 2-bit logic-level translator offers a wide voltage range, output enable capability, and tiny packaging.
This configurable, dual-supply voltage translator is practical for use in digital circuits to translate from lower to higher logic levels or vice versa, especially 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V. The device's 1.1 V to 3.6 V range provides a lower voltage threshold than most alternatives, allowing it to better accommodate the low voltage needs of ultra-portable applications, including cell phones, digital cameras and notebooks, the company said.
Packaged in a space-efficient 10-terminal MicroPak, the translator is especially designed for “transparently” adding two additional bits to an existing bidirectional translation path, such as a higher-definition LCD or stand-alone 2-bit translation solution for USB port data I/Os, including Memory Stick, and other memory modules.
Key performance benefits of the translator include increased functionality, miniaturization and improved reliability.
The output enable (3-state) function allows full reverse data flow without conflicts at the translator's opposing I/O terminals and eliminates the need for power-consuming bus hold operations or additional pull-up/-down resistors.
The MicroPak chip-scale package (1.6mm x 2.1mm) provides up to 45 percent printed-circuit board space savings over competing translators in leaded packages; and with up to 1.5 to 3 times the terminal contact area of bumped chips, for a rugged alternative to other wafer level chip scale packaging (WCSP).
