FXL4TD245 is the industry’s first four-bit, low-voltage dual-supply voltage translator with independent-direction controls. The unique control feature increases design flexibility by allowing designers to control the direction of each bit individually compared with typical configurations that control the direction of bidirectional voltage translators in groups of four, eight, or 16 bits. The translator’s wide voltage range of 1.1 to 3.6 V simplifies designs and accommodates the voltage requirements of a variety of consumer and industrial applications. In addition, the voltage translator’s ultracompact (2.5 × 3.5 mm) DQFN package provides 65% board space savings versus TSSOP packaging, making it suitable for space-constrained, ultraportable computing and consumer applications. The voltage translator is fully configurable: 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 designers to select the translation levels and set the high side or low side according to their specifications.
