FAIRCHILD Semiconductor, represented by Arrow Electronics , has announced the industry's first single-bit, dual-voltage translator buffer - the ultra low power FXLP34.

Useful in cell phones, PDAs, notebooks, digital cameras and other battery-powered portable devices, the FXLP34 translator allows designers to mix and match different voltage levels, thus providing a low-noise buffered interface between any 1.0-3.6V logic state, including 1.6V, 1.8V, 2.5V and 3.3V.

Fairchild's new CMOS-based ultra low power consumption technology enables nanosecond speed propagation delays along with ultra low power consumption.

The FXLP34 single-bit translator buffer utilises two separate supply voltages (VCC and VCC1) to translate between logic voltages within a 0.9V-3.6V range.

Translation propagation delays (tPD) vary according to supply voltage level-for example, VCC values of 3.0V-3.6V experience 4ns propagation delays; while VCC values of 1.4V-1.6V typically provide 7ns prop delays.

The FXLP34 device is available in either leadless chip-scale packaging (MicroPak) or 5-lead SC70. Either form factor provides a flexible design solution that meets the needs of battery-powered portables with limited space for new-feature circuitry.
