TXU0202QDCURQ1

The TXU0202-Q1 is a 2-bit dual-supply non-inverting directional voltage-level translator with Schmitt-trigger inputs and 3-state outputs. 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. Port A accepts input voltages from 1.1V to 5.5V, and Port B also accepts input voltages from 1.1V to 5.5V. When OE is driven high with respect to either supply, directional data transfer from A to B or from B to A can occur. When OE is driven low, all output pins are in a high-impedance state. For all available packages, refer to the Orderable Product Addendum at the end of the datasheet.

Applications

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

Key features

• Fully configurable dual supply rail design allows each port to operate from 1.1V to 5.5V
• Supports data rates up to 200Mbps in the 3.3V to 5.0V range
• Schmitt-trigger inputs accommodate slow and noisy input signals
• Inputs with integrated static pull-down resistors prevent channel floating
• High drive strength (up to 12mA at 5V)
• Low power consumption: 2.5 μA max (25℃), 6 μA max (-40℃ to 125℃)
• VCC isolation and VCC disconnect (Ioff-float) feature: if either VCC input falls below 100mV or is disconnected, all outputs are disabled and placed in a high-impedance state
• Ioff supports partial power-down mode operation
• Control logic (OE) with VCC(MIN) circuit allows control from either Port A or Port B
• Pin-compatible with TXB series level translators
• TXU0102 is an alternative part available to support common applications
• Operating temperature range: -40℃ to +125℃
• Latch-up performance exceeds 100 mA per JESD 78 Class II
• ESD protection exceeds JESD 22 requirements, including 2500V Human Body Model and 1500V Charged Device Model
