INVERTER<br />

The <strong>ITT</strong>935, <strong>ITT</strong>936, and <strong>ITT</strong>937 elements are hex<br />

single-input inverters.<br />

The <strong>ITT</strong>935 is intended for use with discrete diode<br />

expansion <strong>of</strong> the input. When extending inputs with<br />

diodes, care should be taken to minimize<br />

capacitance on the input node.<br />

These inverter gates can be cross-coupled to form<br />

a flip-flop or the outputs can be tied together to<br />

perform the "wired OR" function.<br />

ThelTT936 incorporates a 6K output pull-up<br />

resistor which allows for a fan-out <strong>of</strong> up to 8 OTL<br />

loads.<br />

The <strong>ITT</strong>937 incorporates a 2K output pull-up<br />

resistor which typically results in a 30% faster rise<br />

time with capacitive loads at a fan-out <strong>of</strong> up to 7<br />

OTL loads.<br />

The <strong>ITT</strong>938 has uncommitted collector outputs,<br />

making the device useful as a lamp driver or other<br />

interface element.<br />

2. Allow 300·C/Watt OJ-A for 1/4" x 1/4"<br />

flatpack and dual in-line. Allow 50· C/Watt<br />

OJ-C for TO-5; 180·C/Watt OJ-C for 1/4"<br />

x 1/4" flatpack and dual in-line. Heat removal<br />

in 1/4" x 1/4" flatpack is highly dependent<br />

upon contact surfaces or air flow and on lead<br />

attachment and thermal paths thru leads, as<br />

well as number <strong>of</strong> soldered leads.<br />
