描述 Description

The UTC ULSF010X family supports up to 100MHz uptranslation and greater than 100MHz down translation at≤30pF capload and up to 40MHz up/down translation at 50pF cap load whichallows the UTC ULSF010X family to support more consumer ortelecom interfaces (MDIO or SDIO). The UTC ULSF010X familyhas bidirectional voltage translation without the need for DIR pinwhich minimizes system effort(for PM Bus, I2C, or SM Bus).The UTC ULSF010X family supports 5V tolerance on I/O portwhich makes it compatible with TTL levels in industrial and telecomapplications. The UTC ULSF010X family is able to setup differentvoltage translation levels on each channel which makes it veryflexible.

特性 Features

Provides bidirectional voltage translation with no direction pin Supports up to 100MHz up translation and greater than 100MHzdown translation at ≤ 30pF cap load and up to 40MHz up/downtranslation at 50pF cap load. Allow bidirectional voltage level translation between– 0.95V?1.8/2.5/3.3/5V– 1.2V?1.8/2.5/3.3/5V– 1.8V?2.5/3.3/5V– 2.5V?3.3/5V– 3.3V?5V Low standby current 5V tolerance I/O port to support TTL Low RON provides less signal distortion High-Impedance I/O pins for EN=Low
