- No direction-control - Data rates 24 Mbps (Push Pull) 2 Mbps (Open Drain)

- 1.65V to 3.6V on A port and 2.3V to 5.5V on B port (VCCA ≤ VCCB)

- VCC isolation feature:If either VCC input is at GND,both ports are in the high-impedance state

- No power-supply sequencing required:either VCCA or VCCB can be ramped first

- Ioff supports partial-power-down mode operation

- Operating temperature range:-40℃ to +85℃

This 8-bit non-inverting translator which is a bidirectional voltage-level translator and can be used to build digital switching compatibility between multi voltage systems.This IC uses two separate configurable power supply tracks that including A ports supporting operating voltages from 1.65V to 3.6V with tracking VCCA supply,and also including B ports supporting operating voltages from 2.3V to 5.5V with tracking VCCB supply.The advantage above provides the support of both lower and higher logic signal levels while providing bidirectional translation capabilities between any of the 1.8-V, 2.5-V, 3.3-V, and 5-V voltage circuit points.Placing output-enable (OE) input to low level,all I/Os are forced to high-impedance state that significantly lower the quiescent current consumption.In order to ensure the high-impedance state during power up or power down,OE pin should be tied to GND via a pulldown resistor;the minimum value of the resistor is determined by the current-sourcing capability of the driver.
