The 'ALVTH32244 devices are 32-bit buffers/line drivers designed for 2.5-V or 3.3-V VCC operation, but with the capability to provide a TTL interface to a 5-V system environment. These devices can be used as eight 4-bit buffers, four 8-bit buffers, two 16-bit buffers, or one 32-bit buffer. These devices provide true outputs and symmetrical active-low output-enable (OE\) inputs.

When VCC is between 0 and 1.2-V, the devices are in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.2-V, OE\ should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

These devices are fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down. The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down, which prevents driver conflict.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

The SN54ALVTH32244 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALVTH32244 is characterized for operation from -40°C to 85°C.
