TXS0102DCUR-HXY

This 2-bit non-inverting translator is a bidirectional voltage-level translator designed to establish digital switching compatibility between multi-voltage systems. The IC features two independently configurable supply rails: Port A supports an operating voltage of 1.65 V to 3.6 V and tracks the VccA supply; Port B supports an operating voltage of 2.3 V to 5.5 V and tracks the VccB supply. These features provide support for both lower and higher logic-level signals while enabling bidirectional translation between 1.8 V, 2.5 V, 3.3 V, and 5 V voltage nodes. When the output enable (OE) input is driven low, all I/O ports are forced into a high-impedance state, significantly reducing quiescent current consumption. To maintain the high-impedance state during power-up or power-down, the OE pin should be connected to GND through a pull-down resistor; the minimum value of this resistor is determined by the current-sourcing capability of the driver.

Applications

• Mobile Phone/Smartphone
• MART
• IPC
• GPIO

Key features

• No direction control required
• Data rate: 24 Mbps (push-pull), 2 Mbps (open-drain)
• Port A voltage range 1.65V to 3.6V, Port B voltage range 2.3V to 5.5V (VCCA ≤ VCCB)
• VCC isolation feature: if either VCC input is at GND, both ports are in high-impedance state
• No power sequencing required: VCCA or VCCB can power up first
• IOFF supports partial power-down mode operation
• Operating temperature range: -40°C to +85°C
