74VCX16240 Low-Voltage 1.8/2.5/3.3V 16-Bit Buffer
With 3.6 VTolerant Inputs and Outputs (3State, Inverting)
The 74VCX16240 is an advanced performance, inverting 16bit buffer. It is designed for very highspeed, very lowpower operation in 1.8 V, 2.5 V or 3.3 V systems. When operating at 2.5 V (or 1.8 V) the part is designed to tolerate voltages it may encounter on either inputs or outputs when interfacing to 3.3 V busses. It is guaranteed to be overvoltage tolerant to 3.6 V. The 74VCX16240 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.

4. For CL = 50pF, add approximately 300ps to the AC maximum specification. 5. 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.
