What is the meaning of 7400 Series?
7400-series meaning Filters. The designation for more than 400 different digital logic integrated circuits, including NAND and NOR gates, inverters, buffers, decoders, frequency dividers, shift registers, flip-flops and binary adders.
What is a function of IC 7400?
7400 IC is the most widely used TTL (Transistor-Transistor Logic) device in the world. It contains four independent two-input NAND gates. Its popularity is based on the fact that any logic gate function can be created using only NAND gates.
What does 74 mean in IC?
Two digits, where “74” denotes a commercial temperature range device and “54” denotes a military temperature range. Historically, “64” denoted a short-lived series with an intermediate “industrial” temperature range.
What are the different CMOS series available?
Quad 2-input gates
- 4001 quad 2-input NOR.
- 4011 quad 2-input NAND.
- 4030 quad 2-input EX-OR (now obsolete)
- 4070 quad 2-input EX-OR.
- 4071 quad 2-input OR.
- 4077 quad 2-input EX-NOR.
- 4081 quad 2-input AND.
- 4093 quad 2-input NAND with Schmitt trigger inputs.
What is the difference between the 7400 series and the 5400 series?
The main difference between the two was the temperature range; 5400-series devices generally operated from -55 to 125C, while the 7400 parts, housed in inexpensive plastic packages, were rated from 0 to 70C.
Why it is called IC 7400?
7400 7402. mentions that it has dual inline package and 7 pins each side. 4 represents number of gates last two digits r meant for type code.
What is meant by 74LS?
The 74LS (Low-power Schottky) family (like the original) uses TTL (Transistor-Transistor Logic) circuitry which is fast but requires more power than later families. The 74HC family has High-speed CMOS circuitry, combining the speed of TTL with the very low power consumption of the 4000 series.
How do you read an IC?
Read the serial number from the top side of the IC. The top side of the IC is facing up when the chip is standing on its pins. You may require a magnifying glass while reading the IC serial information.
How many 74ls00 inputs can a 74ls00 NAND gate drive?
The 74xxyy ICs are logic gates of digital electronics. 74LS00 IC has four NAND gates. Also each gate has two inputs. Hence name QUAD TWO INPUT NAND GATE….74LS00 Pin Configuration.
| Pin Number | Description |
|---|---|
| NAND GATE 1 | |
| 1 | A1-INPUT1 of GATE 1 |
| 2 | B1-INPUT2 of GATE 1 |
| 3 | Y1-OUTPUT of GATE1 |
Which is part of the CD4000 IC series?
CD4009 Hex Inverter/Buffer is a part of the CD4000 IC series. It is also characterized for usage as CD4002B NOR gate IC provides the system designer with direct implementation of the NOR function and supplements the
What are the chips in the CMOS 4000 series?
CD4000 Series of CMOS Logic Chips including AND, OR, NAND Gates as well as counters, shift registers and multiplexers. CD4522 Program. BCD Divide-by-N Counter
When was the CD4000 COS / MOS series introduced?
The 4000 series was introduced as the CD4000 COS/MOS series in 1968 by RCA as a lower power and more versatile alternative to the 7400 series of transistor-transistor logic (TTL) chips. The logic functions were implemented with the newly introduced Complementary Metal–Oxide–Semiconductor (CMOS) technology.
When did the 4000 series of ICs come out?
The 4000 series is a CMOS logic family of integrated circuits (ICs) first introduced in 1968 by RCA. It had a supply voltage range of 5V to 20V, which is much higher than any contemporary logic family. Almost all IC manufacturers active during this initial era fabricated models for this series.
