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 main-
taining low static power dissipation over a very broad VCC
■ Space saving SOT23 or SC70 5-lead package
■ Ultra small MicroPak leadless package
■ Ultra High Speed; tPD 2.6 ns Typ into 50 pF at 5V VCC
■ High Output Drive; ±24 mA at 3V 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
■ Broad VCC Operating Range; 1.65V to 5.5V
■ Matches the performance of LCX when operated at
3.3V VCC
voltages up to 6V independent of VCC operating voltage.
The output tolerates voltages above VCC in the 3-STATE
condition.
■ Power down high impedance inputs/output
■ Overvoltage tolerant inputs facilitate 5V to 3V
translation
■ Patented noise/EMI reduction circuitry implemented
