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