The TXS0104EPWR is a 4-bit Bidirectional Voltage-level Shifter for open-drain and push-pull applications. This non-inverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA and accepts any supply voltage from 1.65 to 3.6V. VCCA must be less than or equal to VCCB. The B port is designed to track VCCB and accepts any supply voltage from 2.3 to 5.5V. This allows for universal low-voltage bidirectional translation between any of the 1.2, 1.5, 1.8, 2.5, 3.3 and 5V voltage nodes. When the output-enable (OE) input is low, all outputs are placed in the high-impedance state. The TXS0104E is designed so that the OE input circuit is supplied by VCCA. 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.
- No direction-control signal needed
- Maximum data rates (24Mbps (push pull), 2Mbps (open drain))
- 1.65 to 3.6V on A port and 2.3 to 5.5V on B port (VCCA <= VCCB)
- No power-supply sequencing required, either VCCA or VCCB can be ramped first
- Latch-up performance exceeds 100mA per JESD 78, class II
- Green product and no Sb/Br
