Revised February 2005 NC7SZ126 TinyLogic£ UHS Buffer with 3-STATE Output General Description Features The NC7SZ126 is a single buffer with 3-STATE output 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 range. The inputs and output are high impedance above ground when VCC is 0V. Inputs tolerate voltages up to 6V independent of VCC operating voltage. The output tolerates voltages above VCC in the 3-STATE condition. ■ Space saving SOT23 or SC70 5-lead package ■ Ultra small MicroPak¥ Pb-Free leadless package ■ Ultra High Speed; tPD 2.6 ns Typ into 50 pF at 5V VCC ■ High Output Drive; r24 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 NC7SZ126M5X MA05B 7Z26 5-Lead SOT23, JEDEC MO-178, 1.6mm 3k Units on Tape and Reel NC7SZ126P5X MAA05A Z26 5-Lead SC70, EIAJ SC-88a, 1.25mm Wide 3k Units on Tape and Reel NC7SZ126P5X_NL (Note 1) MAA05A Z26 Pb-Free 5-Lead SC70, EIAJ SC-88a, 1.25mm Wide 3k Units on Tape and Reel NC7SZ126L6X MAC06A FF Pb-Free 6-Lead MicroPak, 1.0mm Wide 5k Units on Tape and Reel Package Description Supplied As 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 3: Unused inputs must be held HIGH or LOW. They may not float.
