# TTL and CMOS logic gate types

ic types of logic gates. For practice or experiment using logic gate you can use logic gate made of switch, diode, relay and so on. This time the admin will explain the types of logic gate ic along with the schematics that can be used for practice. so after reading this article you will know what are the types of TTL logic gate and CMOS logic gate

Logic gates can be made from switches, diodes, relays and so on

But the above components have some shortcomings one of which is the speed when there is a change of condition from high to low and vice versa and large component size

For that use Ic is the right thing besides the price is cheaper and also relatively smaller

Example if we make nand gate using relay hence required component and also expensive price

To make a gate and required 2 relay components

Unlike the ic, in ic there are 4 pieces of logic gate that we can get with affordable price

## The following Types of Ic Gate Logic (TTL logic gate and CMOS logic gate)

Ic gate logic consists of 2 types

1. TTL type

Ic type TTL (transistor transistor logic) requires a maximum working voltage of 5 VDC. On ic ttl input pins are not connected everywhere considered logic

To make a power supply for IC type TTL you can read the article of 5v 1A stabilizer circuit

2. CMOS type

Ic CMOS using working voltage 3-15VDC. on ic cmos input PINs that are not in use must still be given a certain condition (0 or 1). If allowed to float then ic will quickly break down

## TTL logic gate

Here are the types of logic gate ic of type ttl

### TTL and gate

To make the and gate of TTL type can be used ic 7408. This IC consists of 4 pieces of and gate which has 2 inputs

The location of the legs as shown below

### TTL or gate

To make or gate from TTL type can be used ic 7432. This IC consists of 4 pieces of or gate which has 2 inputs. Read what is or gate and how does it work?

The location of the legs as shown below

### TTL not gate

To make the not gate of TTL type can be used ic 7404. This IC consists of 6 pieces of your gate

The location of the legs as shown below

### TTL nor gate

To make the nor gate of TTL type can be used ic 7402. This IC consists of 4 pieces of nor gate which has 2 inputs

Read the article on what is nor gate and how does it work?

The location of the legs as shown below

### TTL xor gate

To make the xor gate of TTL type can be used ic 7486. This IC consists of 4 pieces of xor gate which has 2 inputs

Read the article on what is xor gate and how does it work?

The location of the legs as shown below

All types of ICs above are TTL ICs so you should not be wrong when installing a voltage source

IC TTL requires 5VDC voltage. But if you do not find the TTL IC type above you can also use the type of ICMOS. ICMOS has a greater voltage range up to 15V

## CMOS logic gate

In addition to using TTL ic logic gate can also be made by using ICMOS. Here are the types of logic gate ic of cmos type

### CMOS and gate

To make the gate and of CMOS type can be used ic 4081. This IC consists of 4 pieces of your gate which has 2 inputs

The location of the legs as shown below

### CMOS or gate

To make a gate or of type CMOS can be used ic 4071. This IC consists of 4 pieces of gate or has 2 inputs

The location of the legs as shown below

### CMOS not gate

To make the gate not of TTL type can be used ic 4069. This IC consists of 6 pieces of gate notes

The location of the legs as shown below

### CMOS nand gate

To make the nand gate of CMOS type can be used ic 4011. This IC consists of 4 nand gates that have 2 inputs

The location of the legs as shown below

### CMOS nor gate
