Introduction of ST2329B 2-bit dual supply level translator without direction control pin, open drain output
The ST2329B is a 2-bit dual supply level translator designed for data transfer in multi-voltage systems. It utilizes a transmission gate-based design to provide bi-directional level translation without a direction control pin. The device accepts a low voltage supply (VL) ranging from 1.65 to 3.6 V and a high voltage supply (VCC) from 1.80 to 5.5 V, making it suitable for interfacing low-voltage ASICs/PLDs with higher voltage systems.
