ST2189 8-bit dual supply level translator without direction control pin

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.

技术特性

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)
