The logical sum is the same as the "arithmetic sum"

F

Not every chip requires power and ground

F

The NOT function has one input and one output

T

TTL and CMOS devices differ not in their logic functions, but in their construction and electrical characteristics

T

For the NAND gate we can say all inputs HIGH make the output HIGH

F

How many basic logic functions are there that can be combined to make any other logic?

Three

NAND

An _______ is shown by a bubble or an arrow symbol on the affected terminal.

active LOW

When inverting gates such as NAND and NOR are enabled, they will invert an input signal passing it to the
gate output; in other words, they transmit the signal in _______.

complement form

________ is a sophisticated technology that relies on automatic placement of chips and soldering of pins onto the surface of a circuit board, not through holes in the board

SMT

Digital data are transferred from more than one source to one or more destinations along a common wire or
_____.

Bus

___________, also called a NOT gate, is a logic gate that changes its input logic level to the opposite state

inverting buffer

A _______________ is a list of all possible input values to a digital circuit, listed in ascending binary order, and the output response for each input combination
