ST2189QTR

ST2189 8-bit dual supply level translator without direction control pin Features ■ 46 MHz: 92 Mbps data transfer when VCCA = 3.6 V ■ Bidirectional level translation without direction control pin ■ Wide voltage range of 1.65 V to 3.6 V for both VCCA and VCCB ■ Configurable voltage translation: – VCCA can be ≥ VCCB or VCCA can be ≤VCCB ■ Partial power down support - when VCCB is grounded, all the outputs will automatically go to high impedance. ■ Low quiescent current (5 µA) ■ ESD performance: – ±4 kV HBM (human body model) Applications ■ Low voltage system level translation ■ Mobile phones ■ Other mobile devices QFN20 (1.8 x 3.2 mm) Description The ST2189 is an 8-bit dual supply level translator which provides the level shifting capability to allow data transfer in a multi-voltage system. Externally applied voltages, VCCB and VCCA, set the logic levels on either side of the device. Its architecture allows bidirectional level translation without a control pin. The ST2189 accepts VCCA from 1.65 V to 3.6 V and VCCB from 1.65 V to 3.6 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. In power down mode feature - when VCCB supply is grounded, all I/Os go to high impedance automatically, with very low quiescent current on VCCA supply. Table 1.

The device requires the driver to source/sink a maximum current of (VCC/4) mA to/from the weak 4 kΩ output buffer in order to change the state of the output. 3.2 Load driving capability To support the level translation without direction pin architecture, the one-shot transistor at the output side is only turned ON during state transition. After the one-shot transistor is turned OFF, only the 4 kΩ pull-up/down resistor maintains the state of the output. As a result, resistive load or pull-up resistor less than 50 kΩ is not recommended. 3.3 Ensuring low current consumption during off state The OE pin can be tied to the enable signal which is driving the enable pin of the slave device to ensure that the device will turn off and put all I/Os to tri-state mode whenever the slave device is not needed. On the event that the enable signal driving into the slave device is active low, the signal going into the OE pin for ST2189 (active high) needs to be inverted accordingly. Alternatively, a pull-down resistor can be added to the VCCB supply. This will ensure that the VCCB supply does not float whenever the supply is turned off. All the I/Os go to high impedance automatically when this happens. 3.4 Truth table Table 3. Truth table Enable Bidirectional Input/Output OE I/OVCCB I/OVCCA H(1) H(2) H(1) H(1) L L (3) L High-Z 1.
