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
• 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
TXU0101-Q1 is a 1-bit, dual-supply noninverting fixed
direction voltage level translation device. The A pin
is referenced to VCCA logic level, the OE pin can be
referenced to either VCCA or VCCB logic levels, and
the B pin is referenced to VCCB logic level. 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 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.
