TXS0104E-Q1에 대한 설명
The TXS0104E-Q1 device connects an incompatible logic communication from chip-to-chip due to voltage mismatch. This auto-direction translator can be conveniently used to bridge the gap without the need of direction control from the host. Each channel can be mixed and matched with different output types (open-drain or push-pull) and mixed data flows (transmit or receive) without intervention from the host. This 4-bit noninverting translator uses two separate configurable power-supply rails. The A and B ports are designed to track V CCA and V CCB respectively. The V CCB pin accepts any supply voltage from 2.3 V to 5.5 V while the V CCA pin accepts any supply voltage from 1.65 V to 3.6 V such that V CCA is less than or equal to V CCB. This tracking 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.
The TXS0104E-Q1 device is designed so that the OE input circuit is supplied by V CCA.
To be in the high-impedance state during power up or power down, the OE pin must be tied to the GND pin through a pull down resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
