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 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.

Features

■ 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

■ 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)
