SCES831F – SEPTEMBER 2011 – REVISED MAY 2016 TXB0304 4-Bit Bidirectional Level-Shifter/Voltage Translator with Automatic Direction
Sensing
1 Features 3 Description This 4-bit non-inverting translator uses two separate
configurable power-supply rails. The A port is
designed to track VCCA. VCCA accepts any supply
voltage from 0.9 V to 3.6 V. The B port is designed to
track VCCB. VCCB accepts any supply voltage from
0.9 V to 3.6 V. This allows for low Voltage
bidirectional translation between 1 V, 1.2 V, 1.5 V, 1.8
V, 2.5 V and 3.3 V voltage nodes. For the TXB0304,
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. The OE device control pin input circuit is …
