NTE9949 fiche technique
NTE9946 & NTE9949
Integrated Circuit
DTL, Quad, 2Input NAND Gate
Description:
The NTE9946 and NTE9949 are DTL integrated circuits in a 14Lead DIP type package consisting
of four 2input NAND gate circuits. These devices can be used as dual 2input noninverting gates
or as two bistable circuits when two dual 2input gates are crosscoupled.
Features:
D PullUp Resistor:
NTE9946 6kΩ
NTE9949 2kΩ
