NC7SZ38
TinyLogic UHS 2-Input NAND Gate (Open Drain Output)
General Description
Features
■ Space saving SOT23 or SC70 5-lead package
■ Open Drain output stage for OR tied applications
■ Ultra High Speed; tPD 2.4 ns Typ into 50 pF at 5V VCC
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
■ 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-
■ Matches the performance of LCX when operated at
3.3V VCC
■ Power down high impedance inputs/output
ating voltage. The open drain output stage will tolerate volt-
ages up to 6V independent of VCC when in the high
■ Overvoltage Tolerant inputs facilitate 5V to 3V
translation
impedance state.
■ Patented noise/EMI reduction circuitry implemented
