What is a 74HC series? The 74HC family of logic devices are high speed, low power devices that use CMOS circuitry. The devices are pin compatible with many existing devices such as the 74TTL, 74STTL and 4000 series.
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.
What does sn mean on IC? An IC has generally first 2–3 letters and then 4–6 numbers…the letters stands for the manufacturer… such as SN for Texas, MC for Motorola, uA for Fairchild,LM for national semiconductor, etc…..the numbers are the company’s designation for each IC..
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 gate is 7404?
Description. 7404 is a NOT Gate IC ,This a 14 pin DIP version of the popular NOT Gate IC. 7404 is a NOT gate IC. It consists of six inverters which perform logical invert action.
What is the difference between LS and HC IC?
“The main difference between the LS and HC is the logic of 74XX. The 74LS is Transistor to Transistor logic. Uses Shottky transistors to reduce the stored charge and get higher switching speeds then with conventional bipolar transistors. The 74HC uses MOSFET technology.
Is 74HC compatible with 74LS?
The 74HCT family is a special version of 74HC with 74LS TTL-compatible inputs so 74HCT can be safely mixed with 74LS in the same system. In fact 74HCT can be used as low-power direct replacements for the older 74LS ICs in most circuits.
Can 74HC drive 74LS?
The short answer is you can drive LS with HC, but the inverse is not true. 74HCT and 74LS are compatible in both directions. In addition, 74HC and 74HCT are compatible both ways. You have to be aware of fanout limitations in all cases.
Are TTL chips still made?
Quantum jump to transistor-transistor-logic, TTL, which in its variants, is still in limited use today.
What is the difference between 74HC and 74HCT?
The difference between 74HC and 74HCT is the input circuitry. The outputs of both series can drive LSTTL or CMOS, but the 74HCT inputs have TTL level compatible tresholds.
What are the differences between the 74HC family and the 4000 series CMOS ICs?
The difference depends on your system definition. On the one hand, 74HC operates over a limited voltage range, with 6 volts specified as the maximum supply voltage. The CD4000 series, on the other hand, is rated to a maximum of 18 volts, so it may well be easier to use the CD4000 series in a battery-operated system.
What type of IC is 7400?
IC 7400, NAND gate. 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 is the difference between 74LS and 74HC?
difference between 74ls 74hc. The 74LS is Transistor to Transistor logic. Uses Shottky transistors to reduce the stored charge and get higher switching speeds then with conventional bipolar transistors. The 74HC uses MOSFET technology. Therefore can operate with wider variety of voltages.
