DTL DUAL FIVE
INPUT GATE
The ITT1800 is a dual five input NAND/NOR gate.
The device is similar to the ITT930 in all respects,
except for the replacement of the expander node
with a standard input diode.

NOTES:
1. Above which useful life may be impaired.
2. Allow 300·e/Watt OJ-A for 1/4" x 1/4"
flatpack and dual in-line. Allow 50·e/Watt
OJ-C for TO-5; lBO·e/Watt OJ-C for 1/4"
x 1/4" flat pack and dual in-line. Heat removal
in 1/4" x 1/4" flatpack is highly dependent
upon contact surfaces or air flow and on lead
attachment and thermal paths thru leads, as
well as number of soldered leads.
