Q1:

The term "hex inverter" refers to:

A an inverter that has six inputs

B six inverters in a single package

C a six-input symbolic logic device

D an inverter that has a history of failure

ANS:B - six inverters in a single package

The hex inverter is an integrated circuit that contains six (hexa-) inverters. For example, the 7404 TTL chip which has 14 pins and the 4049 CMOS chip which has 16 pins, 2 of which are used for power/referencing, and 12 of which are used by the inputs and outputs of the six inverters (the 4049 has 2 pins with no connection).
