Texas Instruments  TXS0102QDCURQ1

The TXS0102-Q1 device connects an incompatible logic communication from chip-to-chip dueto voltage mismatch. This auto-direction translator can be conveniently used to bridge the gapwithout the need of direction control from the host. Each channel can be mixed and matched withdifferent output types (open-drain or push-pull) and mixed data flows (transmit or receive) withoutintervention from the host. This 4-bit noninverting translator uses two separate configurablepower-supply rails. The A and B ports are designed to track VCCA andVCCB respectively. The VCCB pin accepts any supplyvoltage from 2.3 V to 5.5 V while the VCCA pin accepts any supply voltagefrom 1.65 V to 3.6 V such that VCCA is less than or equal toVCCB. This tracking allows for low-voltage bidirectional translation betweenany 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-impedancestate.

The TXS0102-Q1 device is designed so that the OE input circuit is supplied byVCCA.

To assure the high-impedance state during power up or power down, the OE pin must be tiedto the GND pin through a pulldown resistor; the minimum value of the resistor is determined by thecurrent-sourcing capability of the driver.
