NC7WZ240 TinyLogic UHS Dual Inverting Buffer with 3-STATE Outputs
March 2001 Revised April 2003
NC7WZ240 TinyLogic UHS Dual Inverting Buffer with 3-STATE Outputs
General Description
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.

Note 1: Absolute maximum ratings are DC values beyond which the device may be damaged or have its useful life impaired. 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 5: Parameter guaranteed by design. tOSLH = |tPLHmax - tPLHmin|; tOSHL = |tPHLmax - tPHLmin|. 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).
