TXS0102DQER

The TXS0102DQER is a 2-bit Bidirectional Voltage Level Shifter for open-drain and push-pull application. This non-inverting translator is a bidirectional voltage-level translator and can be used to establish digital switching compatibility between mixed-voltage systems. It uses two separate configurable power-supply rails, with the A ports supporting operating voltages from 1.65 to 3.6V while it tracks the VCCA supply and the B ports supporting operating voltages from 2.3 to 5.5V while it tracks the VCCB supply. This allows the support of both lower and higher logic signal levels while providing bidirectional translation capabilities between any of the 1.8, 2.5, 3.3 and 5V voltage nodes. When the OE input is low, all I/Os are placed in the high-impedance state, which significantly reduces the power-supply quiescent current consumption. To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pull-down resistor.

• No direction-control signal needed
• VCC Isolation feature - If either VCC input is at GND, both ports are in the high-impedance state
• No power-supply sequencing required - Either VCCA or VCCB can be ramped first
• Ioff Supports partial-power-down mode operation
• Latch-up performance exceeds 100mA per JESD 78, Class II
• 24Mbps (push pull) Maximum data rates
• 2Mbps (open drain) Maximum data rates
• Green product and no Sb/Br
