Revised January 2005 NC7WZ38 TinyLogic UHS Dual 2-Input NAND Gate (Open Drain Output) General Description Features 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. ■ Space saving US8 surface mount package ■ MicroPak Pb-Free leadless package ■ Open Drain output stage for OR tied applications ■ Ultra High Speed; tPD 2.2 ns Typ into 50 pF at 5V VCC ■ High Output Sink Drive; 24 mA at 3V VCC ■ Broad VCC Operating Range; 1.65V to 5.5V ■ Matches the performance of LCX when operated at 3.3V VCC ■ Power down high impedance inputs/output ■ Overvoltage Tolerant inputs facilitate 5V to 3V translation ■ Patented noise/EMI reduction circuitry implemented Ordering Code: Product Order Package Code Number Number Top Mark NC7WZ38K8X MAB08A WZ38 NC7WZ38L8X MAC08A U5 Package Description Supplied As 8-Lead US8, JEDEC MO-187, Variation CA 3.1mm Wide 3k Units on Tape and Reel Pb-Free 8-Lead MicroPak, 1.6 mm Wide 5k Units on Tape and Reel Pb-Free package per JEDEC J-STD-020B.

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.
