FAST DTl QUAD
TWO-INPUT OR GATE
The ITT 1808 and 1809 elements are quad two
input positive ORI negative AND gates. In
addition to performing the OR function with full
fanout available, outputs can be connected
together to perform the wire-AND function,
thereby reducing system complexity.
Pinout: Dual In-Line and Flat Pack
The ITT1808 incorporate a 6K output pull-up
resistor which allows for a fan-bur of up to 8
DTL loads.
The ITT1809 incorporates a 2K output pull-up
resistor which typically results in a 30% faster
rise time with capacitive loads at a fan-out of
up to 7 DTL loads.

NOTES:
1. Above which useful life may be impaired.
2. Allow 300°C/Watt OJ-A for 1/4" x 1/4"
flatpack and dual in-line. Allow 50°C/Watt
OJ-C for TO-5; 180°C/Watt OJ-C for 1/4"
x 1/4" flatpack 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.
