Descripción de TXB0304
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.
