3 Description
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 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.
