ST2129B Description

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 translation without a control pin.
