STMicroelectronics ST2129B
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. Its architecture allows bi-directional level translation without a control pin. The ST2129B device accepts VL from 1.65 to 3.6 V and VCC from VL to 5.5 V, making it ideal for data transfer between low-voltage ASICs/PLD and higher voltage systems.| Part No. | ST2129B |

DESCRIPTION
Externally applied voltages, VCC and VL, set the logic levels on either side of the device. The ST2129B device accepts VL from 1.65 to 3.6 V and VCC from VL to 5.5 V, making it ideal for data transfer between low-voltage ASICs/PLD and higher voltage systems. This device has a tristate output mode which can be used to disable all I/Os. Order code ST2129BQTR Table 1.
