TXU0102DCUR

The TXU0102 is a 2-bit dual-supply non-inverting directional 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. 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 relative to either supply, directional data transfer from A to B or B to A can occur. When OE is driven low, all output pins are placed in a high-impedance state.

Applications

• Eliminates slow or noisy input signals
• Drives indicator LEDs or buzzers
• Mechanical switch debouncing
• General-purpose I/O level translation
• 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, supporting up to 200Mbps at 3.3V to 5.0V
• Schmitt-trigger inputs for slow and noisy input signals
• Input with integrated static pull-down resistors to prevent bus current flow
• High drive strength (up to 12mA at 5V)
• Low power consumption:
• 2.5μA max (25°C)
• 6μA max (−40°C to 125°C)
• VCC isolation and VCC disconnect (Ioff-float) feature: if either VCC input drops 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 port A or B
• Pin-compatible with TXB series level translators
• Operating temperature range: −40°C to +125°C
• Latch-up performance exceeds 100mA per JESD 78 Class II
• ESD protection exceeds JESD 22 specifications:
• 2500V Human Body Model
• 1500V Charged Device Model
