NC7SZ27
TinyLogic UHS 3-Input NOR Gate
General Description
Features
■ Space saving SC70 6-lead package
The NC7SZ27 is
a
single 3-Input NOR Gate 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
■ Ultra small MicroPak leadless package
■ Ultra High Speed: tPD 2.4 ns typ into 50 pF at 5V VCC
■ High Output Drive: ±24 mA at 3V VCC
■ Broad VCC Operating Range: 1.65V–5.5V
■ Power down high impedance inputs/output
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.
■ Overvoltage tolerant inputs facilitate 5V to 3V
translation
■ Patented noise/EMI reduction circuitry implemented
