1 Features
• Fully configurable dual-rail design allows each port
to operate from 1.1 V to 5.5 V
• Up to 200 Mbps support for 3.3 V to 5.0 V
• Schmitt-trigger inputs allows for slow and noisy
inputs
• Inputs with integrated static pull-down resistors
prevent channels from floating
• High drive strength (up to 12 mA at 5 V)
• Low power consumption
– 2.5 μA maximum (25°C)
– 6 μA maximum (–40°C to 125°C)
• VCC isolation and VCC disconnect (Ioff-float) feature
– If either VCC input is ;amplt;100 mV or
disconnected, all outputs are disabled and
become high-impedance
• Ioff supports partial-power-down mode operation
• Control logic (OE) with VCC(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
– 2500-V human-body model
– 1500-V charged-device model

2 Applications
• Eliminate slow or noisy input signals
• Driving indicator LEDs or buzzers
• Debouncing a mechanical switch
• General purpose I/O level shifting
• Push-pull level shifting (UART, SPI, JTAG, and so
forth)

3 Description
TXU0102-Q1 is a 2-bit, dual-supply noninverting fixed
direction voltage level translation device. The Ax pins
are referenced to VCCA logic level, the OE pin can be
referenced to either VCCA or VCCB logic levels, and
the Bx pins are referenced to VCCB logic levels. The A
port can accept input voltages ranging from 1.1 V to
5.5 V, while the B port can also accept input voltages
from 1.1 V to 5.5 V. Fixed direction data transmission
can occur 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.
See Device Functional Modes for a summary of the
operation of the control logic.
