FXLH42245 Low-Voltage, Dual-Supply, 8-Bit, Signal Translator with Configurable Voltage Supplies, Bushold Data Inputs, 3-State Outputs and 26Ω Series Resistors in the B-Port Outputs Features Description Bi-Directional Interface between Two Levels from 1.1V to 3.6V Fully Configurable, Inputs Track VCC Level Outputs Remain in 3-State until Active VCC Level is Reached 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 of voltage levels: 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. Outputs Switch to 3-State if Either VCC is at GND 26W Output Series Resistors on the B Port to Reduce Line Noise Power-Off Protection Packaged in 24-Pin MLP Non-Preferential Power-up; Either VCC May Be Powered-up First Bushold on Data Inputs Eliminates the need for External Pull-Up / Pull-Down Resistors Control Inputs (T/R, OE) Levels are Referenced To VCCA Voltage The device remains in 3-state until both VCCs 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. 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: © 2004 Fairchild Semiconductor Corporation FXLH42245 • Rev. 1.0.3 1. Drive OE input HIGH to disable the device. 2. Remove power from either VCC. 3. Remove power from the other VCC.
