Level Translator 20-Pin QFN T/R

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.

46 MHz: 92 Mbps data transfer when V_CCA = 3.6 V

Bidirectional level translation without direction control pin

Wide voltage range of 1.65 V to 3.6 V for both V_CCA and V_CCB

Configurable voltage translation: V_CCA can be = V_CCB or V_CCA can be = V_CCB

Partial power down support - when V_CCB is grounded, all the outputs will automatically go to high impedance.

Low quiescent current (5 µA)

ESD performance: ±4 kV HBM (human body model)
