NC7WZ38 TinyLogic UHS Dual 2-Input NAND Gate (Open Drain Output)
April 2000 Revised January 2005
NC7WZ38 TinyLogic UHS Dual 2-Input NAND Gate (Open Drain Output)
General Description
The NC7WZ38 is a dual 2-Input NAND Gate with open drain output stage from Fairchild's Ultra High Speed Series of TinyLogic. The device is fabricated with advanced CMOS technology to achieve ultra high speed with high output drive while maintaining low static power dissipation over a very broad VCC operating range. The device is specified to operate over the 1.65V to 5.5V VCC range. The inputs and output are high impedance when VCC is 0V. Inputs tolerate voltages up to 7V independent of VCC operating voltage. The open drain output stage will tolerate voltages up to 7V independent of VCC when in the high impedance state.

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: Unused inputs must be held HIGH or LOW. They may not float.

Note 3: 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) + (ICC static).
