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
■ 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
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 oper-
