STMicroelectronics ST2329B
The ST2329B device is a 2-bit dual supply level translator which provides the level shifting capability to allow data transfer in a multi-voltage system. It utilizes a transmission gate-based design that allows bi-directional level translation without a control pin. The ST2329B device accepts VL from 1.65 to 3.6 V and VCC from 1.80 to 5.5 V, making it ideal for data transfer between low-voltage ASICs/PLD and higher voltage systems.| Part No. | ST2329B |

DESCRIPTION
DESCRIPTION
Externally applied voltages, VCC and VL, set the logic levels on either side of the device. This device has a tristate output mode which can be used to disable all I/Os. The ST2329B device supports power-down mode when VCC is grounded/floating and the device is disabled via the OE pin. DocID023359 Rev 3 5/23 Pin settings 2 Pin settings 2.1 Pin connection Figure 1.
