FXL4T245: Low Voltage Dual Supply 4-Bit Signal Translator with Configurable Voltage Supplies and Signal Levels and 3-STATE Outputs
Description: The FXL4T245 is a configurable dual-voltage-supply...
The FXL4T245 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 bi-directional 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/R#) input determines the direction of data flow through the device. The OE# input, when HIGH, disables both the A and B Ports by placing them in 3-STATE condition. The FXL4T245 is designed so that the control pins (T/R# and OE#) are supplied by VCCA.
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
Control inputs (T/R#, OE#) levels are referenced to VCCA voltage
