Revised May 2003 NC7SZ38 TinyLogic UHS 2-Input NAND Gate (Open Drain Output) General Description Features The NC7SZ38 is a single 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 6V independent of VCC operating voltage. The open drain output stage will tolerate voltages up to 6V independent of VCC when in the high impedance state. ■ Space saving SOT23 or SC70 5-lead package ■ Ultra small MicroPak leadless package ■ Open Drain output stage for OR tied applications ■ Ultra High Speed; tPD 2.4 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: Order Package Product Code Number Number Top Mark NC7SZ38M5X MA05B 7Z38 5-Lead SOT23, JEDEC MO-178, 1.6mm NC7SZ38P5X MAA05A Z38 5-Lead SC70, EIAJ SC-88a, 1.25mm Wide 3k Units on Tape and Reel NC7SZ38L6X MAC06A A6 6-Lead MicroPak, 1.0mm Wide 5k Units on Tape and Reel Package Description Pin Descriptions Supplied As 3k Units on Tape and Reel Logic Symbol Pin Names Description A, B Inputs Y Output NC No Connect Function Table Connection Diagrams Pin Assignments for SC70 and SOT23 Y = AB Inputs IEEE/IEC Output A B Y L L *H L H *H H L *H H H L (Top View) Pad Assignment for MicroPak H = HIGH Logic Level L = LOW Logic Level *H = HIGH Impedance output state (Open Drain) (Top Thru View) TinyLogic is a registered trademark of Fairchild Semiconductor Corporation.

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. Power Dissipation (PD) @ +85°C SOT23-5 200 mW SC70-5 150 mW Note 2: Unused inputs must be held HIGH or LOW.
