Revised April 2003 NC7WZ240 TinyLogic UHS Dual Inverting Buffer with 3-STATE Outputs General Description Features The NC7WZ240 is a Dual Inverting Buffer with independent active LOW enables for the 3-STATE outputs. The Ultra High Speed device is fabricated with advanced CMOS technology to achieve superior switching performance with high output drive while maintaining low static power dissipation over a broad VCC operating range. The device is specified to operate over the 1.65V to 5.5V VCC operating range. The inputs and outputs are high impedance when VCC is 0V. Inputs tolerate voltages up to 5.5V independent of VCC operating range. Outputs tolerate voltages above VCC when in the 3-STATE condition.

The datasheet specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation outside datasheet specifications. Note 2: The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed. Note 3: Unused inputs must be held HIGH or LOW. They may not float.

Note 6: C PD is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption (ICCD ) at no output loading and operating at 50% duty cycle. (See Figure 2.) CPD is related to ICCD dynamic operating current by the expression: ICCD = (CPD)(VCC)(fIN) + (ICCstatic). www.fairchildsemi.com 4 NC7WZ240 AC Loading and Waveforms CL includes load and stray capacitance Input PRR = 1.0 MHz; tw = 500 ns FIGURE 1.
