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 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 state.
The TXS0104E-Q1 device is designed so that the OE
input circuit is supplied by VCCA.
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.
