ST2129B Overview
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.
ST2129B Key Features
- 45 MHz: 90 Mbps (max.) data rate at VL = 1.8 V, VCC = 3.3 V
- Bi-directional level translation without direction control pin
- Wide voltage range (VL ≤ VCC)
- VL ranges from 1.65 to 3.6 V
- VCC ranges from VL to 5.5 V
