TXB0108DQSR

The TXB0108DQSR is a 8-bit bidirectional Voltage Level Shifter with an auto direction sensing. This 8-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 to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 to 5.5V. VCCA should not exceed VCCB. When the OE input is low, all outputs are placed in the high-impedance state. The TXB0108 is designed so that the OE 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. To ensure the high-impedance state during power-up or power-down, OE should be tied to GND through a pull-down resistor.

• VCC Isolation - If either VCC input is at GND, all outputs are in the high-impedance state
• OE Input circuit referenced to VCCA
• 4µA Maximum low power consumption
• Ioff Supports partial-power-down mode operation
• Latch-up performance exceeds 100mA per JESD 78, Class II
• Green product and no Sb/Br
