Bus-Hold Option Available
Translator Nomenclature
Features
- Fully-configurable, bi-directional translation to/from all voltages between 1.2-V and 3.6-V (AVC devices) and 1.65-V and 5.5-V (LVC devices) on either port
- If either VCC is turned off, then both ports are in the Hi-Z mode, no power sequencing concerns
- Bus-hold circuitry available
- Ioff feature allows partial power-down operation
Benefits
- Flexible Voltage Translation Range
- Low-power Operation
- Eliminates the need for external Pull-up/down Resistors
End Equipment
- Handsets
- PDAs
- Digital Cameras
Applications
- LCD Interface (16-32 Bit)
- SPI-Bus Voltage Translation (1 - 2 Bit)
- Clock Buffering and Level Shifting (1 Bit)
- Mixed-Voltage I/O’s (8 - 16 Bit)
