TXU0204BQAR

The TXU0204 is a 4-bit, dual-supply, non-inverting, fixed-direction voltage-level translator. The Ax pins are referenced to VCCA logic levels, the OE pin can be referenced to either VCCA or VCCB logic levels, and the Bx pins are referenced to VCCB logic levels. The A port accepts input voltages ranging from 1.1 V to 5.5 V, and the B port also accepts input voltages from 1.1 V to 5.5 V. When OE is driven high relative to either supply, fixed-direction data transfer can occur from A to B or from B to A. When OE is driven low, all output pins enter a high-impedance state. For a summary of the control logic operation, refer to the Device Functional Modes.

Applications

• Eliminates slow or noisy input signals
• Drives indicator LEDs or buzzers
• Debounces mechanical switches
• General-purpose I/O level shifting
• Push-pull level translation (UART, SPI, JTAG, etc.)
