TXB0104
    发布时间: 2023-06-05 09:34    

Voltage-level translators address the challenges posed by simultaneous use of different supply-voltage levels on the same circuit board. 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 1.2 V to3.6 V. The B port is designed to track VccB. VccB accepts any supply voltage from 1.65 V to 5.5 V. This allows for univers allow-voltage bidirectional translation between any of the 1.2-V，1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. VccA should not exceed VccB. When the output-enable (OE) input is low, all outputsare 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 thedriver. The TXB0104 is designed so that the OE input circuitis supplied by VccA. This device is fully specified for partial-power-down applications using loff. The loff circuitry disables theoutputs, preventing damaging current back flow through the device when it is powered down.
