Features
Bi-directional interface between any 2 levels from 1.1V to 3.6V Fully configurable: Inputs track V CC level Non-preferential power-up sequencing; either V CC may be powered-up first Outputs remain in 3-STATE until active V CC level is reached Outputs switch to 3-STATE if either V CC is at GND Power-off protection Control inputs (T/R n , OE) levels are referenced to V CCA 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) General Description The FXL4TD245 is a configurable 4-bit dual-voltage- supply translator designed for both uni-directional and bi-directional voltage translation between two logic lev- els. The device allows translation between voltages as high as 3.6V to as low as 1.1V. The A Port tracks the V CCA level, and the B Port tracks the V CCB level. This allows for bi-directional voltage translation over a variety The device remains in 3-STATE until both V CC s reach active levels allowing either V CC to be powered-up first. Internal power down control circuits place the device in 3-STATE if either V CC is removed. The Transmit/Receive (T/R) inputs independently deter- mine 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 V CCA

This benefit derives from the chip design. When either V CC is at 0 volts, outputs are in a HIGH-Impedance state. The control inputs (T/R n and OE) are designed to track the V CCA supply. A pull-up resistor tying OE to V CCA 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 the following: 1. Apply power to either V CC 2. Apply power to the T/R n 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 V CC 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 V CC 3. Remove power from other V CC Pin Number Terminal Name CCA
