FXL4TD245 tm Low Voltage Dual Supply 4-Bit Signal Translator with Configurable Voltage Supplies and Signal Levels and 3-STATE Outputs and Independent Direction Controls Features General Description ■ Bi-directional interface between any 2 levels The FXL4TD245 is a configurable 4-bit dual-voltagesupply translator designed for both uni-directional and bi-directional voltage translation between two logic 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. This allows for bi-directional voltage translation over a variety of voltage levels: 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. ■ ■ ■ ■ ■ ■ ■ ■ from 1.1V to 3.6V Fully configurable: Inputs track VCC level Non-preferential power-up sequencing; either VCC may be powered-up first Outputs remain in 3-STATE until active VCC level is reached Outputs switch to 3-STATE if either VCC is at GND Power-off protection Control inputs (T/Rn, OE) levels are referenced to VCCA voltage Packaged in 16-Terminal DQFN (2.5mm x 3.5mm) ESD protections exceeds: – 4kV HBM ESD (per JESD22-A114 & Mil Std 883e 3015.7) – 8kV HBM I/O to GND ESD (per JESD22-A114 & Mil Std 883e 3015.7) – 1kV CDM ESD (per ESD STM 5.3) – 200V MM ESD (per JESD22-A115 & ESD STM5.2) The device remains in 3-STATE until both VCCs reach active levels allowing either VCC to be powered-up first. Internal power down control circuits place the device in 3-STATE if either VCC is removed. The Transmit/Receive (T/R) inputs independently determine the direction of data through each of the four bits. The OE input, when HIGH, disables both the A and B Ports by placing them in a 3-STATE condition. The FXL4TD245 is designed so that the control pins (T/R and OE) are supplied by VCCA.

This benefit derives from the chip design. When either VCC is at 0 volts, outputs are in a HIGH-Impedance state. The control inputs (T/Rn 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 pullup resistor is based upon the current-sinking capability of the OE driver. Pin Assignment Pin Number Terminal Name 1 VCCA 2 T/R0 3–6 A0–A3 7 T/R3 8 GND 9 OE 10 T/R2 11–14 B3–B0 15 T/R1 16 VCCB The recommended power-up sequence is the following: 1. Apply power to either VCC. 2. Apply power to the T/Rn inputs (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 other VCC. 4. Drive the OE input LOW to enable the device. The recommended power-down sequence is the following: 1. Drive OE input HIGH to disable the device. 2. Remove power from either VCC. 3. Remove power from other VCC. ©2006 Fairchild Semiconductor Corporation FXL4TD245 Rev. 1.0.4 www.fairchildsemi.com 2 FXL4TD245 Low Voltage Dual Supply 4-Bit Signal Translator with Configurable Voltage Supplies and Signal Levels and 3-STATE Outputs and Independent Direction Controls Functional Diagram The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed.
