General Description
The NC7SZ38 is a single 2-Input NAND Gate with open
drain output stage from Fairchild’s Ultra High Speed Series
of TinyLogic
CMOS technology to achie ve ultra high speed with high
output drive while maintaining low static power dissipation
over a very broad V
specified to operate over the 1.65V to 5.5V V
inputs and output are high impedance when V
Inputs tolerate voltages up to 6V inde pe nde nt o f V
ating voltage. The open drain output stage will tolerate volt-
ages up to 6V independent of V
impedance state.
