ST2129B Datasheet (STMicroelectronics) - 2-bit dual supply level translator

ST2129B, 2-bit dual supply level translator

The ST2129B device is a 2-bit dual supply level translator which provides the level shifting capability to allow data transfer in a multi-voltage system.

Externally applied voltages, VCC and VL, set the logic levels on either side of the device.

 Its architecture allows bi-directional level transla
