Product overview
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, VCCand VL,set the logic levels on either side of the device. Its architecture allows bi-directional level translation without a control pin.
The ST2129B device accepts VLfrom 1.65 to 3.6 V and VCCfrom VLto 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.
