UM3608 are octal bus transceivers that utilize deep micron CMOS Technology are intended for bus oriented application. This 8-bit non-inverting bus transceiver uses two separate configurable power-supply rails to implement universal low voltage bidirectional translation between any of the 1.8V,2.5V,3.3V and 5.5V voltage nodes. The UM3608 is  optimized  to  operate  with  VCCA and  VCCB  set  at  1.65V  to  5.5V.  The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.65V to 5.5V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65V to 5.5 V.
The UM3608 is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) input and the output-enable (OE) input activate either the B-port outputs or the A-port outputs or place both output ports into the high-impedance mode. The device transmits data from the A bus to the B bus when the B-port outputs are activated, and from the B bus to the A bus when the A-port outputs are activated. The input circuitry on both A and B ports must have a logic HIGH or LOW level applied to prevent excess ICC and ICCZ.
UM3608 is fully specified for partial power down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging the current back flow through the device when it is powered down. The VCC isolation feature ensures that if either VCC Input is at GND, all outputs are in the high impedance state. To ensure the high impedance state during power up or power down. OE should be tied to VCC through a pull up resistor. The UM3608 is designed so that the control pins (DIR and OE) are supplied by VCCA.
