Two-way voltage translator goes low

Single-bit bidirectional voltage translator is guaranteed to operate from 1.1 to 3.6V.

New from Fairchild Semiconductor, the FXLH1T45 is billed as the industry's only single-bit bidirectional voltage translator with guaranteed operation from 1.1 to 3.6V, providing ease of design for ultraportable computing, communication and industrial applications.

This single-bit bidirectional translator seamlessly interfaces processors to electronic subsystems operating at different voltage levels by providing both unidirectional and bidirectional translation between a variety of voltage levels.

Its 1.1V operation makes the FXLH1T45 ideal for the low-power requirements of ultraportable applications.

To conserve space and increase system reliability, the FXLH1T45 is available in Fairchild's ultracompact (1.0 x 1.45mm) 6-terminal MicroPak package, saving 65% more board space than translators in SC70 packages.

The MicroPak package's large 0.2 x 0.3mm land grid array (LGA) contact pads assure strong joint integrity essential for reliable operation under harsh environmental stressors, such as excessive jarring or stresses due to impact.

The FXLH1T45 provides the added benefit of being fully configurable for maximum design flexibility.

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 the user to select the translation levels and set the high side or low side as desired.

In addition to the rugged and compact packaging, the FXLH1T45's bushold on the data outputs eliminates the need for external pull-up or pull-down resistors, further saving board space.

The FXLH1T45 uses lead-free (Pb-free) terminals and has been characterised 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 RoHS Directive.

Samples are available now.
