† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. This current flows only when the output is in the high state and V_O > V _CC. 3. The package thermal impedance is calculated in accordance with JESD 51.

The SN54ALVTH32244 is 32-bit buffers/line drivers designed for 2.5-V or 3.3-V V_CC 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. SN54ALVTH32244 provides true outputs and symmetrical active-low output-enable (OE) inputs.

When V_CC is between 0 and 1.2-V, the SN54ALVTH32244 is 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 V_CC through a pullup resistor; the minimum value of the resistor SN54ALVTH32244 is determined by the current-sinking capability of the driver.

SN54ALVTH32244 is fully specified for hot-insertion applications using Ioff and power-up 3-state. The I_off 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 of SN54ALVTH32244 in the high-impedance state during power up and power down, which prevents driver conflict.

Active bus-hold circuitry of SN54ALVTH32244 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.
