WebEmitter Coupled Logic (ECL) Unipolar Logic Families: It mainly uses Unipolar devices like MOSFETs in addition to passive elements like resistors and capacitors. These logic families have the advantages of high speed and lower power consumption than Bipolar families. These are classified as: PMOS or P-Channel MOS Logic Family WebThe AND of two bits is a logic '1', if and only if both the input bits are also logic '1'. AND logic is very helpful in implementing 'inhibit' functions. A common TTL IC with AND gate function is the 7408. This IC contains four 2 input AND gates. = Where A and B are inputs and X is the output.

WebA differential amplifier is used as the input stage emitter coupled logic gates and as switch. When used as a switch, the "left" base/grid is used as signal input and the "right" base/grid is grounded; output is taken from the right collector/plate. When the input is zero or negative, the output is close to zero (but can be not saturated); when ...
