7406 HEX INVERTER
with OPEN-COLLECTOR HIGH VOLTAGE outputs

POSITIVE LOGIC





The 7406 IC package contains six independent positive logic NOT GATES (INVERTERS). Pins 14 and 7 provide power for all four logic gates. The Open-Collector outputs require pull-up resistors for proper logical operation. The outputs are rated for up to 30 VOLTS at 30mA.

These gates can be used to interface TTL to high-level circuits such as MOS. Inputs are diode clamped to minimize transmission effects.

NOT GATE Logic-Rules:

The output is the inverse of the input, in otherwords if the input is HIGH then the out put is LOW and if the input is LOW the output is HIGH.
