st2149b description doc id 023310 rev 1 5/23 1 description the st2149b is a 4-bit dual supply level translator which provides the level shifting capability to allow data transfer in a mult i-voltage system. externa lly applied voltages, v cc and v l , set the logic levels on either side of the device. its architecture allows bi-directional level translation without a control pin. the st2149b accepts v l from 1.65 to 3.6 v and v cc from v l 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.

st2149b supplementary notes doc id 023310 rev 1 9/23 4 supplementary notes 4.1 driver requirement 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. 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 k resistor maintains the output logic state. so, a resistive load or pull-up resistor less than 50 k is not recommended for proper operation. 4.3 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)
