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. The ST2149B 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 tri-state output mode which can be used to disable all I/Os. Doc ID 023310 Rev 1 5/23 Pin settings ST2149B 2 Pin settings 2.1 Pin connection Figure 1.

The device architecture requires the driver to source/sink maximum current of (VCC/4) mA to/from the weak 4 kΩ output buffer. 4.2 Load driving capability To support the architecture that allows level translation without the direction pin, the one-shot transistor is turned ON only during state transition at the output side. After the one-shot transistor is turned OFF, only the 4 kΩ resistor maintains the output logic state. So, a resistive load or pull-up resistor less than 50 kΩ is not recommended for proper operation. 4.3 Truth table Table 3.
