Texas Instruments TXU0202 Voltage-Level Translator

Texas Instruments TXU0202 Voltage-Level Translator is a 2-bit, dual-supply non-inverting fixed-direction voltage level translation device. Ax pins are referenced to the V_CCA logic level, an OE pin can be referenced to either V_CCA or V_CCB logic levels, and a Bx pin is referenced to the V_CCB logic levels. The A port can 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 when OE is set to high in reference to either supply. When OE is set to low on the Texas Instruments TXU0202, all output pins are in the high-impedance state.

Features

• A fully configurable dual-rail design allows each port to operate from 1.1V to 5.5V
• Up to 200Mbps support for 3.3V to 5.0V
• Schmitt-trigger inputs allow for slow and noisy inputs
• Inputs with integrated static pull-down resistors prevent channels from floating
• High drive strength (up to 12mA at 5V)
• Low power consumption
  • 2.5µA maximum (25°C)
  • 6µA maximum (–40°C to 125°C)
• V_CC isolation and V_CC disconnect (I_off-float) feature
  • If either V_CC input is < 100mV or disconnected, all outputs are disabled and become high-impedance
• I_off supports partial-power-down mode operation
• Control logic (OE) with V_CC(MIN) circuitry allows for control from either A or B port
• Pinout compatible with TXB family level shifters
• Available in another variant that supports common applications: TXU0102
• Operating temperature from –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
