The Logic Gate NAND 74HC10 is CMOS ( triple 3-input NAND gate). It is a 14 pin package that contains 3 individual NAND gates in it. The IC power source has been limited to a MAXIMUM OF 6V
you can convert the 3 inputs into 2 inputs by connecting any 2 inputs together thus we get 2 inputs.
|1||A Input Gate 1|
|2||B Input Gate 1|
|3||A Input Gate 2|
|4||B Input Gate 2|
|5||C Input Gate 2|
|6||Y Output Gate 2|
|8||Y Output Gate 3|
|9||A Input Gate 3|
|10||B Input Gate 3|
|11||C Input Gate 3|
|12||Y Output Gate 1|
|13||C Input Gate 1|
|14||Vcc - Positive Supply|
While the IC 7410 features only NAND gates, it is possible to connect the NAND gates in a number of ways.
This allows us to convert them into other forms of the gate like:
(1) an inverter or "NOT" gate
(2) an AND gate
(3) an OR gate
(4) NOR gate.
The 7400 is an extremely adaptable IC, And this is the Truth Table of the 74HC10 treble Nand IC:
In order to check a 74HC10 IC, you can apply power across pins 14 and 7. Keep pins 1 and 2 connected to the positive supply, this will show the output as 0.
Next, without changing the pin 2 connection, connect pin 1 to 0 volts. This will enable the inputs to become 1, 0. This will cause the output to turn 1, illuminating the LED. Now simply, swap pin 1 and pin 2 connections, so that the Inputs become 0, 1, this will switch the output to logic 1, shutting off the LED.
In the final step, connect both the input pins 1 and 2 to ground or 0 volts so that the Inputs are at logic 0, 0. This will yet again turns output to logic high or 1, switching ON the LED. The glowing of the LED signifies the logic level 1.
When LED is OFF this suggests logic level 0. The analysis could be repeated for gates B, C, and D.
Note: each of the circuits proven here works with 1/4W 5% resistors
If a circuit fails to work, you may look at the connections, the possibility of a faulty IC may be highly unlikely compared to an incorrect connection of the pins. This connection of a NAND gate shown below may be the most basic and works by using only 1 gate of a 7410.
When the input pins a of a NAND gate are shorted with each other the circuit then works as an inverter, meaning the output logic shows always the opposite of the input.
When the shorted input pins of the gate are connected to 0V, the output will turn into 1 and vice versa. Because the "NOT" configuration provides an opposing response across the input and the output pins, hence the name NOT gate. This phrase is actually a technically appropriate one.
Since a NAND gate is also a kind of a "NOT AND" gate, therefore in case a "NOT" gate is introduced after a NAND gate, the circuit turns into a "NOT NOT AND" gate.
A couple of negatives produce a positive (a notion that's popular in math concepts too). The circuit has now become an "AND" gate as shown above.
Inserting a NOT gate before each NAND gate inputs generates an OR gate as demonstrated above. This is usually a 2 -input OR gate.
In the previous design, we created an OR gate from NAND gates. A NOR gate in fact becomes a NOT OR gate when we add an extra NOT gate just after an OR gate as shown above.
