描述 Description

AW39114 is a 4-bit high-performance voltage-level translator without direction control signal, which is a non-inverting converter ａｎｄ can be used to convertdigital 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 supportboth 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.
