NXU0204GU12X

NXU0204GU12X is a 4bit, dual-supply level translating buffer with Schmitt-trigger inputs and 3-state outputs. It features four data inputs (A1, A2, B3 and B4), four data outputs (YB1, YB2, YA3 and YA4) and an output enable input (OE). This device facilitates asynchronous communication between data buses. Transmit data with a fixed direction (unidirectionally) from the A bus to the B bus on three channels and from the B bus to the A bus for one channel. This device ensures low static and dynamic power consumption across the entire supply range and is fully specified for partial power down applications using IOFF. The IOFF circuitry prevents potentially damaging backflow current through the device when it is powered down or if one of the power supplies is disconnected (floating). Typical applications include general purpose I/O level translation, noisy environments or slow input signals, supports push-pull voltage translation such as UART, SPI and JTAG protocols, consumer.

• Wide supply voltage range: 0.9V to 5.5V (VCCA/VCCB)
• Schmitt-trigger inputs with integrated static high ohmic pull-down resistor on the input
• Maximum data rate: 250Mbps (≥ 1.8V to 5V translation)
• Output enable (OE) allows connection to VCCA or VCCB domain
• Suspend mode when either one of the supply voltages is below 100mV or disconnected (floating)
• Low noise overshoot and undershoot <10% of VCCO
• IOFF circuitry provides partial power-down mode operation
• Latch-up performance exceeds 100mA per JESD78D Class II
• XQFN12 package
• Ambient temperature range from -40 to +125°C
