A MOSFET driver IC translates TTL or CMOS logical signals, to a higher voltage and higher current, with the goal of rapidly and completely switching the gate of a MOSFET. An output pin of a microcontroller is usually adequate to drive a small-signal logic level MOSFET. However driving larger MOSFETs is a different story. Large MOSFETs have.

Difference between TTL CMOS ECL | TTL vs CMOS vs ECL

These are logic familities used in IC (Integrated Circuit) designs.TTL (Transistor Transistor Logic) IC technology uses bipolar transistor as principal circuit element.CMOS (Complementary Metal Oxide Semiconductor) IC technology uses FET as principal circuit element.ECL (Emitter Coupled Logic) IC technology uses bipolar transistors configured as differential amplifier.Let us compare TTL vs CMOS vs ECL logic families in order to derive difference between TTL and CMOS and ECL basedon various parameters such as fan-out, power consumption, noise immunity etc.

TTL | Transistor Transistor Logic

This logic family basic TTL gate has improvement over standard DTL gate.TTL gate has three different types of output configurations:
• Open collector output
• Totem-pole output
• Three state (or tristate) output

Totem pole provides less power dissipation, higher speed of operationand high fanout.

Standard TTL series of logic family starts with suffix 74.
For example: 7404, 74S86 and 74ALS161

The other two families are for military and industrial applications.
54 - military
84 - Industrial (Discontinued)

ECL | Emitter Coupled Logic

ECL is based on use of current steering switch realised using differential transistor pair.ECL eliminates saturation and improves speed but uses more power than other logic familiessuch as TTL and CMOS.

ECL is fastest logic family among all and this is due toavoidance of saturation region for application.

Following are characteristics of ECL logic family.
• propagation rate is about 1 to 2ns
• Noise immunity and power dissipation is worst of all the logic families.
• High Level is -0.8V and Low Level is -1.8V
• It has differential input amplifier,Internal temperature and voltage compensated bias network, emitter follower outputs•

ECL gates provide both true as well as complemented outputs.

CMOS | Complementary Metal Oxide Semiconductor

MOS logic families has more delay as compared to transistor logic families.

Following are the typical features of CMOS logic family:
• lowest power dissipation
• Excellent noise immunity
• High packing density
• Wide range of supply voltage
• High speed
• Highest fan out among all logic families

N Mosfet Ttl

Hello I can make a circuit where the 2n2222 can drive the leds and the arduino can pwm them and it works great. I also can make a circuit with just a irf530 driving some leds on 12v and it also works great. My main goal is to power some resistance wire for a heat bender. I would like to use the 2n222 to push 12v to the irf50 so it fully turns on and off.

I cant get this to work. any tutorials on how to make a mosfet driver with all the talk of non ttl mosfets on here you would think it wouldnt be too hard to find but I cant find anything.

I am thinking the problem arises because I am sinking the negative side of the leds through the transistor instead of putting power out of the transistor should I be using a p chanel transistor to feed the mosfet its 12v to turn on? Or is this just not working because I am using the same 12v supply for both mosfet and transistor.

Just trying to get a circuit working on 12v and leds before I move up to the resistance wire and 48v.
