Voltage Level Translator Without Direction Control Signal Maximum Data Rates 24Mbps (Push Pull) 2Mbps (Open Drain) Power Supply Range: A Port and VCCA: 1.1V to 3.6 V B Port and VCCB: 1.65 V to 5.5 V VCCA ≤ VCCB Pull Up Resistors are Integrated in A Port and B Port No Power-Supply Sequencing Required: Either VCCA or VCCB Can be Ramped First Support Ultra-Low Power Consumption Mode with OE Pin is Low Voltage Level Latch -Up Performance Exceeds ±200mA Under JESD 78 Standard DFN 1.4mm×1.0mm×0.37mm.8L Package FOWLP 0.928mm×1.928mm×0.463mm-8B Package AW39112 is a 2-bit high-performance voltage-level translator without direction control signal, which is a non-inverting converter and can be used to convert digital signal with mixed-voltage systems. It needs two separate power supply rails, with the A ports tracks the VCCA ranging from 1.1V to 3.6 V, and the B ports tracks the VCCB ranging from 1.65 V to 5.5 V. This makes the chip has capabilities of support both lower and higher logic signal levels translation between any of the 1.2V, 1.8 V, 2.5 V, 3.3 V, and 5 V voltage nodes. The OE input circuit is supplied by VCCA. Meanwhile, OE is recommended to be tied to GND through an external pull-down resistor to ensure all I/O to be pulled to the supply voltage. No power supply sequencing requirements means either VCCA or VCCB can be powered up first, and OE should be enabled after both VCCA and VCCB are established. AW39112 is a 2-bit high-performance voltage-level translator without direction control signal, which is a noninverting converter and can be used to convert digital signal with mixed-voltage systems. Port A can support I/O voltages from 1.1V to 3.6 V, while Port B is able to support I/O voltage range from 1.65 V to 5.5 V. The chip uses a transmission gate architecture with an rising edge rate accelerator (one-shot), to increase overall data rate.
