STMicroelectronics ST2149B Datasheet
The ST2149B is a 4-bit dual supply level translator designed to facilitate data transfer in multi-voltage systems. It allows bi-directional level translation without a direction control pin, accepting input voltages (VL) from 1.65V to 3.6V and output voltages (Voc) up to 5.5V. The device features a tri-state output mode controlled by an enable pin and is available in a small QFN12 package.
