1 / 21 page August 2009 Doc ID 15918 Rev 1 1/21 21 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 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 tri- state 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. QFN20 (1.8 x 3.2 mm) Table 1.
