Texas Instruments TXU0102 Dual-Bit Voltage-Level Translator

Texas Instruments TXU0102 Dual-Bit Fixed Direction Voltage-Level Translator features flexible pin configurations. The Ax pins are referenced to the V_CCA logic level, the OE pin can be referenced to either V_CCA or V_CCB logic levels, and Bx pins are referenced to V_CCB logic levels. The A port accepts input voltages ranging from 1.1V to 5.5V, while the B port also accepts input voltages from 1.1V to 5.5V. The fixed direction data transmission occurs 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.

FEATURES

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

Ioff 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: TXU0202
Operating temperature from –40°C to +125°C
Latch-up performance exceeds 100 mA per JESD 78, class II
ESD protection exceeds JESD 22
- 2500V human-body model
- 1500V charged-device model
