3 Description
This 4-bit non-inverting translator uses two separate
configurable power-supply rails. The A port is
designed to track VCCA. VCCA accepts any supply
voltage from 0.9 V to 3.6 V. The B port is designed to
track VCCB. VCCB accepts any supply voltage from
0.9 V to 3.6 V. This allows for low Voltage
bidirectional translation between 1 V, 1.2 V, 1.5 V, 1.8
V, 2.5 V and 3.3 V voltage nodes. For the TXB0304,
when the output-enable (OE) input is low, all outputs
are placed in the high-impedance state. To ensure
the high-impedance state during power up or power
down, OE should be tied to GND through a pull-down
resistor; the minimum value of the resistor is
determined by the current-sourcing capability of the
driver. The OE device control pin input circuit is
supplied by VCCA. This device is fully specified for
partial-power-down applications using Ioff. The Ioff
circuitry disables the outputs, preventing damaging
current backflow through the device when it is
powered down. The only difference between
TXB0304 and TXBN0304 is the OE signal being
active high and active low respectively.
