Texas Instruments Inc. (TI) introduced what it claims as the world's first multiple-function, single-supply, logic level translator. Providing designers with PCB space savings and reduced BoM part count, the SN74AUP1T97/98 combines common Boolean logic functions and level translation into a single device. This new product offers up to 9 configurable gate logic functions, including 4 functional combinations not found in traditional logic gates. Utilizing TI's Low power AUP (Advanced Ultra Low Power) logic technology, this level translator offers very low static and dynamic power consumption for battery-operated end-equipments.

The new translator has a single supply-voltage pin, which simplifies trace routing and provides reduced power consumption. The device is optimized to accept 1.8V LVCMOS input signals, while operating from a single 3.3V Vcc supply (1.8V to 3.3V translation), and can also perform voltage translation from 1.8V to 2.5V, 2.5V to 3.3V and 3.3V to 2.5V. The AUP1T97/98 employs Schmitt Trigger Inputs, which eliminate input noise, improve output signal integrity, and allow slow transition of the input signal.

Both the SN74AUP1T97 and SN74AUP1T98 are offered in the 1.4-by-0.9mm Nanostar and NanoFree (Pb-free) wafer chip scale packages, as well as traditional SC-70 and SOT-23 packages. The devices are already available for sampling. Pricing for both the SN74AUP1T97DCKR and the SN74AUP1T98DCKR is set at 24 cents in quantities of 1,000.
