74LVC16244ADGGRG4

This 16-bit buffer/driver is designed for 1.65-V to 3.6-V VCC operation.The SN74LVC16244A device is designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.The SN74LVC16244A device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. The device provides true outputs and symmetrical active-low output-enable (OE) inputs.Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V and 5-V system environment.This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.To ensure the high-impedance state during power up or power down, 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.
