What is a function of IC 7402?
7402 IC is a device containing four independent gates each of which performs the logic NOR function. 7402 package options include: plastic small outline, ceramic chip carriers, flat packages, plastic and ceramic DIPs. The SN7402, SN74LS02 and SN74S02 are characterized for operation from 0°C to 70°C.
What is NOR gate IC?
The NOR gate is a digital logic gate that implements logical NOR – it behaves according to the truth table to the right. A HIGH output (1) results if both the inputs to the gate are LOW (0); if one or both input is HIGH (1), a LOW output (0) results. NOR is the result of the negation of the OR operator.
What is the output pin of IC 7402?
Pin 13 will be used as the output pin for the final NOR gate of the IC.
What is 74HC02?
The 74HC02; 74HCT02 is a quad 2-input NOR gate. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of V CC.
What is NOR and NAND gate?
The NAND and NOR gates are universal gates. In practice, this is advantageous since NAND and NOR gates are economical and easier to fabricate and are the basic gates used in all IC digital logic families. In fact, an AND gate is typically implemented as a NAND gate followed by an inverter not the other way around!!
How many transistors are in a 7402 chip?
There are four NOR gates in the IC and each gate has two inputs, hence the name QUADRUPLE TWO INPUT NOR GATE. The gates in the chip are designed by low power SCHOTTKY TRANSISTORS….74LS02 Pin configuration.
| Pin Number | Description |
|---|---|
| 4 | 2Y-OUTPUT of GATE2 |
| NORGATE 3 | |
| 8 | 3A-INPUT1 of GATE 3 |
| 9 | 3B-INPUT2 of GATE 3 |
What is 74HC32?
The 74HC32 is a 14 Pin Quad 2-Input OR Gate IC. The 74HC32 provides four independent 2-input OR gates with standard push-pull outputs. The device is designed for operation with a power supply range of 2.0V to 6.0V. Inputs include clamp diodes.
What does a XOR gate do?
It is used in simple digital addition circuits which calculate the sum and carry of two (half-adder) or three (full-adder) bit numbers. XOR gates are also used to determine the parity of a binary number, i.e., if the total number of 1’s in the number is odd or even.
What is ex nor?
1. The XNOR gate (sometimes ENOR, EXNOR or NXOR and pronounced as Exclusive NOR. Alternatively XAND, pronounced Exclusive AND) is a digital logic gate whose function is the logical complement of the Exclusive OR (XOR) gate. It is equivalent to the logical connective (
