The ST2189 is an 8-bit dual supply level translator which provides the level shifting capability to allow data transfer in a multi-voltage system. It allows bidirectional level translation without a control pin. It accepts VCCA from 1.65 V to 3.6 V and VCCB from 1.65 V to 3.6 V, making it ideal for data transfer between low-voltage ASICs/PLD and higher voltage systems.
The ST2189 is an 8-bit dual supply level translator designed to facilitate data transfer in multi-voltage systems. It supports bidirectional level translation without a direction control pin and operates with a wide voltage range of 1.65 V to 3.6 V for both VCCA and VCCB supplies. The device features a tri-state output mode and partial power-down support, where grounding VCCB automatically places all outputs in high impedance with low quiescent current.
