74ALVC16244 Low-Voltage 1.8/2.5/3.3 V 16-Bit Buffer
With 3.6 VTolerant Inputs and Outputs (3State, NonInverting)
The 74ALVC16244 is an advanced performance, noninverting 16bit buffer. It is designed for very highspeed, very lowpower operation in 1.8 V, 2.5 V or 3.3 V systems. T h e 74ALVC16244 is nibble controlled with each nibble functioning identically, but independently. The control pins may be tied together to obtain full 16bit operation. The 3state outputs are controlled by an Output Enable (OEn) input for each nibble. When OEn is LOW, the outputs are on. When OEn is HIGH, the outputs are in the high impedance state.

To ensure the outputs activate in the 3state condition, the output enable pins should be connected to VCC through a pullup resistor. The value of the resistor is determined by the current sinking capability of the output connected to the OE pin.

Maximum Ratings are those values beyond which damage to the device may occur. Exposure to these conditions or conditions beyond those indicated may adversely affect device reliability. Functional operation under absolute maximumrated conditions is not implied. Functional operation should be restricted to the Recommended Operating Conditions. 1. IO absolute maximum rating must be observed. 2. Measured with minimum pad spacing on an FR4 board, using 10 mmby1 inch, 2ounce copper trace with no air flow. 3. Tested to EIA/JESD22A114A. 4. Tested to EIA/JESD22A115A. 5. Tested to JESD22C101A. 6. Tested to EIA/JESD78.

10. For CL = 50 pF, add approximately 300 ps to the AC maximum specification. 11. Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The specification applies to any outputs switching in the same direction, either HIGHtoLOW (tOSHL) or LOWtoHIGH (tOSLH); parameter guaranteed by design.
