Description

AI
The 'ALVTH16244 devices are 16-bit buffers/line drivers designed for 2.5-V or 3.3-V VCCoperation, but with the capability to provide a TTL interface to a 5-V system environment. These devices can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. When VCCis between 0 and 1.2 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.2 V, the output-enable (OE\) input should be tied to VCCthrough 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 Ioffand power-up 3-state. The Ioffcircuitry 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. The SN54ALVTH16244 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALVTH16244 is characterized for operation from -40°C to 85°C.
