FXL4T245BQX

FXL4T245BQX 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 bidirectional voltage translation over a variety of voltage levels: 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. 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/active low R) input determines the direction of data flow through the device.

• Bi-directional interface between any 2 levels from 1.1V to 3.6V
• Fully configurable, inputs track VCC level
• Non-preferential power-up sequencing; either VCC may be powered-up first
• No power-up sequencing required, 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/R, active low OE) levels are referenced to VCCA voltage
• ESD protection exceeds 4kV HBM ESD (per JESD22-A114 & Mil Std 883e 3015.7)
• kV 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)
• 14 terminal DQFN package, -40 to +85°C free air operating temperature range
