SCES638C – OCTOBER 2007 – REVISED DECEMBER 2015
TXS0101 1-Bit Bidirectional Level-Shifting, Voltage-Level Translator With Auto-Direction-
Sensing for Open-Drain and Push-Pull Applications
1 Features
•1 No Direction-Control Signal Needed
• Maximum Data Rates
– 24 Mbps (Push Pull)
– 2 Mbps (Open Drain)

3 Description
This one-bit non-inverting translator uses two
separate configurable power-supply rails. The A port
is designed to track V_CCA. V_CCA accepts any supply
voltage from 1.65 V to 3.6 V. The B port is designed
to track V_CCB. V_CCA must be less than or equal to
V_CCB. V_CCB accepts any supply voltage from 2.3 V to
5.5 V. This allows for low voltage bidirectional
translation between any of the 1.8 V, 2.5 V, 3.3 V,
and 5 V voltage nodes.
When the output-enable (OE) input is low, all outputs
are placed in the high-impedance state.
To ensure the high-impedance state during power up
or power down, OE should be tied to GND through a
pull-down resistor; the minimum value of the resistor
is determined by the current-sourcing capability of the
driver.
