The A port is designed to track VCCA. VCCA accepts any supply voltage from 0.9 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 0.9 V to 3.6 V. This allows for low-voltage translation between 0.9-V, 1.2-V, 1.5-V, 1.8-V, 2.5-V and 3.6-V voltage nodes. For the SN74AVC2T244, when the output-enable ( OE) input is high, all outputs are placed in the high-impedance state. The SN74AVC2T244 is designed so that the OE input circuit is referenced to 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. • • • • • • Wide Operating VCC Range of 0.9 V to 3.6 V Low Static-Power Consumption, 6-µA Max ICC Output Enable Feature Allows User to Disable Outputs to Reduce Power Consumption ±24-mA Output Drive at 3.0 V Ioff Supports Partial Power-Down-Mode Operation Input Hysteresis Allows Slow Input Transition and Better Switching Noise Immunity at Input Maximum Data Rates – 380 Mbps (1.8-V to 3.3-V Translation) – 200 Mbps (
