What is the difference between VS and VSS?

What is the difference between VS and VSS?

Going back a ways, Vs refers to any (V)oltage (s)ource. For early logic ICs, which could use odd supply voltages, Vss stood for “substrate voltage”. Sometimes this meant ground, sometimes not.

Is VSS or VDD ground?

No, VDD is the positive power voltage and VSS is the 0 V (or “ground” voltage). D and S refer to “drain” and “source”, respectively. In a single supply circuit, VSS is usually the ground.

What does VSS mean in medical terms?

What is VCC and VSS?

VCC (Voltage Common Collector) is the higher voltage with respect to GND (ground). When the only positive power supply is used then VSS (Voltage Source Supply) means ground or zero. The Intel 8085 Microprocessor needs a power supply of +5 V DC for its working. Pin 40 of Intel 8085 is the Vcc pin.

What is the difference between the VCC and VEE pins on the LCD?

It made sense to call positive supply voltage VCC where the “C” stands for collector. The negative supply was called VEE where “E” stands for emitter. In practice today VCC/VDD means positive power supply voltage and VEE/VSS is for negative supply or ground.

What is VSS VDD and VEE in LCD?

The voltages VCC, VDD, VSS and VEE are used in describing voltages at various common power supply terminals. The differences between these voltages stem from their origins in the transistor circuits they were originally used for. In general VCC and VDD are used for positive voltage, and VSS and VEE are for ground.

What does VCC and VDD mean?

They are all supply voltages. Vcc = Collector supply voltage, Vee = Emitter supply, Vbb= Base supply voltage, Vdd = Drain supply , Vss = source supply. Whenever the supply to a Transistor (or TTL IC circuit) is connected between the collector and ground it is a standard to notify it as Vcc.

What is VCC and Vee?

The VCC and VEE are the notations used for the voltages at various common voltage terminals. VCC stands for Voltage at Common Collector that is the positive supply voltage. VEE stands for Voltage at Common Emitter that is the negative supply voltage.

The VCC, VSS, VDD, and VEE notation are use in naming the voltage at various common voltage power supply terminal only a wire that point between exist power source of specified circuit.

What does VCC mean in electronics?

VCC stands for “voltage at the common collector.”. The letter “V” on a circuit stands for the supply voltage. The letters “CC” indicate that the supply voltage is positive or negative.
