The UM3302 is one channel level translator with auto direction sensing. This 2-channel non-inverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2V to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65V to 5.5V. This allows for universal low-voltage bidirectional translation between any of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V voltage nodes. Both I/O ports are auto-sensing, thus no direction control pin is required, making it ideal for data transfer between low-voltage ASICs/PLDs and higher voltage systems.
The UM3302 operates at a guaranteed data rate of 20Mbps over the entire specified operating voltage range. Within specific voltage domains, higher data rates are up to 100Mbps.
When the output-enable (OE) input is low, all outputs are placed in the high-impedance state. The UM3302 is designed so that the OE input circuit is designed to track VCCA. To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pull down resistor, the minimum value of the resistor is determined by the current-sourcing capability of the driver.
