Since an XOR gate is a three-pin deal, with two inputs and one output, only four XORs fit on the 14-pin chip instead of six inverters. By now, you’re entirely used to the 4000-series logic chips ...

The CMOS 4000 family can reliably sourceor sink 1 mA with a 5V supply. Low-speedTTL can source 0.4 mA and sink8 mA. A 0.4-mA logic-one drive issufficient for the base current, but thelogic zero at ...

Standard CMOS gates used in IC design are inverting for a variety of reasons, including lower area and delay compared to the non inverting versions. So, It would be inefficient to use an inverter when ...

Other logic gates include OR, NOR, XOR, and XNOR, each with different logical functions. Above, we can see how two basic gates are constructed from transistors: an inverter and a NAND gate.

The FET ON/OFF gate-source voltage level lies within the logic signal excursion, and The logic signal source has sufficient drive to cope with the paralleled FET input capacitances. Item 2 is ...
