SN74LVTH16244ADGGR Buffer, Non-Inverting 4 Element 4 Bit per Element 3-State Output 48-TSSOP

DESCRIPTION

The 'LVTH16244A devices are 16-bit buffers and line drivers designed for low-voltage (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 four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. These devices provide true outputs and symmetrical active-low output-enable (OE) inputs.Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended.When VCC is between 0 and 1.5 V, the devices are in the high-impedance state during power up or power down.However, to ensure the high-impedance state above 1.5 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 circuitrydisables 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.
