DUAL HIGH TO LOW INTERFACE<br />

SEMICONDUCTORS<br />

DUAL HIGH TO LOW INTERFACE<br />

The <strong>ITT</strong>361 directly converts HiN I L signal levels<br />

to DTL, TTL, and RTL levels. The 361 output<br />

is connected directly to the low level logic<br />

input, and the 361 low level Vee is connected<br />

to the low level power supply. The 361 can be<br />

used either as an inverting or non-inverting<br />

interface element, but only one <strong>of</strong> these functions<br />

should be used at a time, with the unused<br />

input disabled.<br />
