View All>> Product Description

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 V_CCA and V_CCB set at 1.65V to 5.5V. The A port is designed to track V_CCA. V_CCA accepts any supply voltage from 1.65V to 5.5V. The B port is designed to track V_CCB. V_CCB 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 I_CC and I_CCZ.
UM3608 is fully specified for partial power down applications using I_off. The I_off circuitry disables the outputs, preventing damaging the current back flow through the device when it is powered down. The V_CC isolation feature ensures that if either V_CC 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 V_CC through a pull up resistor. The UM3608 is designed so that the control pins (DIR and OE) are supplied by V_CCA.
