FXMA108 Datasheet | Fairchild Semiconductor

Features - Bi-Directional Interface between Two Levels from 1.65V to 5.5V - Fully Configurable: Inputs and Outputs Track VCC - Non-Preferential Power-Up; 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 - Bus Hold On Data Inputs Eliminates the Need for Pull-Up Resistors - Control Input (/OE) is Referenced to VCCA Voltage - Packaged in 20-Terminal DQFN - Direction Control Not Needed - 80Mbps Throughput when Translating between 2.5V and 5.0V - ESD Protection Exceeds: - 8k V Human Body Model (B Port I/O to GND) (JESD22-A114 & Mil Std 883e 3015.7) - 5k V Human Body Model (A Port I/O to GND) (JESD22-A114 & Mil Std 883e 3015.7) - 2k V Charged Device Model (ESD STM 5.3) (JESD22-C101) Description The FXMA108 is a configurable dual-voltage supply translator designed for both uni-directional and bidirectional voltage translation between two logic levels. The device allows translation between voltages as high as 5.5V to as low as 1.65V. 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: 1.8V, 2.5V, 3.3V, and 5.0V. 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 /OE input, when high, disables both the A and B Side by placing them in a 3-state condition. The /OE input is supplied by VCCA. The FXMA108 supports bi-directional translation without the need for a direction control pin. The two sides of the device have auto-direction-sense capability. Either port may sense an input signal and transfer it as an output signal to the other port.
