Dual-Supply Level Shifters
With two separate VCC supplies, the dual-supply level shifters are suitable for communication between different interface voltages.
Toshiba offers a wide range of bit-width options in ultra-small, thin packages and industry-standard TSSOP.
Application example in which a bidirectional level shifter is needed
The dual-supply bidirectional level shifter is suitable for mixed-voltage systems and provides bidirectional voltage translation between a wide
range of voltage levels.
