st2149 supplementary notes doc id 15949 rev 2 9/23 3 supplementary notes 3.1 driver requirements for proper operation, the driver from each side of the device must be able to source and sink a minimum of 1 ma current. the device architecture requires the driver to source/sink maximum current of (v cc /4) ma to/from the weak 4 k output buffer. 3.2 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 k resistor maintains the state. so, a resistive load or pull-up resistor less than 50 k is not recommended for proper operation. 3.3 power-off feature in some applications it may be required to turn off one of the power supplies powering up the level translator. the device is automatically disabled when v cc supply is turned off, even if the oe pin is set to high (enabled). in this mode, all i/os are in high impedance state. 3.4 truth table table 3. truth table enable bi-directional input/output oe i/o vcc i/o vl h (1) 1. high-level v l power supply referred. h (2) 2. high-level v cc power supply referred. h (1) h (1) ll lz (3) 3. z = high impedance. z (3)
