TXU0101DCKR

The TXU0101 is a 1-bit dual-supply non-inverting directional voltage-level translator. The A pin is referenced to VCCA logic levels, the OE pin can be referenced to either VCCA or VCCB logic levels, and the B pin is referenced to VCCB logic levels. The A port accepts input voltages from 1.1V to 5.5V, and the B port also accepts input voltages from 1.1V to 5.5V. When OE is driven high relative to either supply, directional data translation from A to B 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 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, supporting up to 200Mbps at 3.3V to 5.0V
• Schmitt-trigger inputs for slow and high-noise signals
• Inputs with integrated static pull-down resistors prevent channel flow
• High drive strength (up to 12mA at 5V)
• Low power – max xµA (25°C), max xµA (–40°C to 125°C)
• VCC isolation and VCC disconnect (Ioff-float) – 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 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 – 2500V Human Body Model, 1500V Charged Device Model
