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 VCCA and
VCCB respectively. The VCCB pin accepts any supply
voltage from 2.3 V to 5.5 V while the VCCA pin accepts any supply voltage
from 1.65 V to 3.6 V such that VCCA is less than or equal to
VCCB. 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
The TXS0104E-Q1 device is designed so that the OE input circuit is supplied by
To ensure the high-impedance state during power up or power down, the OE pin must be tied
to the GND pin through a pulldown resistor; the minimum value of the resistor is determined by the
current-sourcing capability of the driver.
