What are the pin numbers of the outputs of the gates in a 7432 IC?
Answer: C
Correct answer: 3, 6, 8, and 11
The 7432 is a quad two-input OR in a 14-pin package, laid out so that each gate takes two adjacent input pins and the next pin is its output. That gives outputs at 3, 6, 8 and 11, with pin 14 for VCC and pin 7 for ground - the same pinout as the 7408 and 7400.

The output of an OR gate with three inputs, A, B, and C, is LOW when ________.
Answer: A
Correct answer: A = 0, B = 0, C = 0
An OR gate is LOW only when every input is LOW; a single 1 makes the output 1.
