To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers.

Description

The FXLH42245 is a configurable dual-voltage-supply translator designed for bi-directional voltage translation of signals between two voltage levels. The device allows translation between voltages as high as 3.6V to as low as 1.1V. The A port tracks the VCCA level and the B port tracks the VCCB level. Both ports are designed to accept supply voltage levels from 1.1V to 3.6V. This allows for bi-directional voltage translation over a variety The device remains in 3-state until both VCC s reach active levels, allowing either VCC to be powered-up first. The device also contains power-down control circuits that place the device in 3-state if either VCC is removed. The Transmit/Receive (T/R) input determines the direction of data flow through the device. The OE input, when HIGH, disables both the A and B ports by placing them in a 3-state condition. The FXLH42245 is designed with the control pins (T/R and OE) supplied by VCCA .

This benefit derives from the chip design. When either VCC is at 0V, outputs are in a High-impedance state. The control inputs (T/R and OE) are designed to track the VCCA supply. A pull-up resistor tying OE to VCCA should be used to ensure that bus contention, excessive currents, or oscillations do not occur during power-up/power-down. The size of the pull-up resistor is based upon the current-sinking capability of the OE driver. The recommended power-up sequence is: 1. Apply power to either VCC . 2. Apply power to the T/R input (logic HIGH for A-to-B operation; logic LOW for B-to-A operation) and to the respective data inputs (A port or B port). This may occur at the same time as step 1. 3. Apply power to the other VCC . 4. Drive the OE input LOW to enable the device. The recommended power-down sequence is: 1. Drive OE input HIGH to disable the device. 2. Remove power from either VCC . 3. Remove power from the other VCC .
