TI TXU0202DCUR

TXU0202 is a 2-bit, dual-supply noninverting fixed direction voltage level translation device. Ax pins are referenced to VCCA logic level, OE pin can be referenced to either VCCA or VCCB logic levels, and Bx pins are referenced to VCCB logic levels. The A port is able to accept input voltages ranging from 1.1V to 5.5V, while the B port can also accept input voltages from 1.1V to 5.5V. Fixed direction data transmission can occur from A to B or B to A when OE is set to high in reference to either supply. When OE is set to low, all output pins are in the high-impedance state.

• Fully configurable dual-rail design allows each port to operate from 1.1V to 5.5V
• Up to 200 Mbps support for 3.3V to 5.0V
• Schmitt-trigger inputs allows for slow and noisy inputs
• Inputs with integrated static pull-down resistors prevent channels from floating
• High drive strength (up to 12 mA at 5V)
• Low power consumption: 2.5 μA maximum (25°C); 6 μA maximum (-40°C to 125°C)
• VCC isolation and VCC disconnect Δ(loff - float) feature. If either VCC input is < 100 mV or disconnected, all outputs are disabled and become high - impedance
• Ioff supports partial - power - down mode operation
• Control logic (OE) with VCC(MIN) circuitry allows for control from either A or B port
• Pinout compatible with TXB family level shifters
• Operating temperature from -40°C to +125°C
• Latch - up performance exceeds 100 mA per JESD 78, class II
• ESD protection exceeds JESD 22: 2500 - V human - body model; 1500 - V charged - device model

• Eliminate slow or noisy input signals
• Driving indicator LEDs or buzzers
• Debouncing a mechanical switch
• General purpose I/O level shifting
• Push - pull level shifting (UART, SPI, JTAG, and so forth)
