The 'LVTH16244A devices are 16-bit buffers and line drivers designed for low-voltage (3.3-V) V operation, butCCwith the capability to provide a TTL interface to a 5-V system environment. These devices can be used as four4-bit buffers, two 8-bit buffers, or one 16-bit buffer. These devices provide true outputs and symmetricalactive-low output-enable (OE) inputs.Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldownresistors with the bus-hold circuitry is not recommended.When V is between 0 and 1.5 V, the devices are in the high-impedance state during power up or power down.CCHowever, to ensure the high-impedance state above 1.5 V, OE should be tied to V through a pullup resistor;CCthe 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 I and power-up 3-state. The I circuitryoff offdisables 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.
