2-Bit Bidirectional Voltage-Level Translator with Automatic Direction Sensing

Check for Samples: TXB0302

FEATURES

DESCRIPTION

This 2-bit noninverting translator uses two separate

configurable power-supply rails. The

voltage from 0.9 V to 3.6 V. The B port is designed to

track VCCB. VCCB accepts any supply voltage from

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

TXB0302, 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

pulldown resistor; the minimum value of the resistor is

determined by the current-sourcing capability of the

driver. The TXB0302 is designed so that the OE input

circuit is supplied by VCCA. This device is fully

specified for partial-power-down applications using

I_off. The I_offcircuitry disables the outputs, preventing

damaging current backflow through the device when

it is powered down.

A. Pull up resistors are not required on both sides for Logic I/O.

B. If pull up or pull down resistors are needed, the resistor value must be over 20 kΩ.

C. 20 kΩ is a safe recommended value, if the customer can accept higher Vol or lower Voh, smaller pull up or pull down

resistor is allowed, the draft estimation is Vol = Vccout × 1.5k/(1.5k + Rpu) and Voh = Vccout × Rdw/(1.5k + Rdw).

D. If pull up resistors are needed, please refer to the TXS0102 or contact TI.

E. For detailed information, please refer to application note SCEA043.
