What is the use of IC 7400?
They are useful for rapid breadboard-prototyping and for education and remain available from most manufacturers. The fastest types and very low voltage versions are typically surface-mount only, however. The first part number in the series, the 7400, is a 14-pin IC containing four two-input NAND gates.
What is 74HC?
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 ic7410?
The IC-7410 has been designed as an HF/50MHz specialized rig with excellent performance and features in this category. The IC-7410 employs high grade DSP unit and double conversion super-heterodyne system developed from the latest technology used in our higher grade rigs such as the IC-7800/7700/7600 series.
Are HC and HCT compatible?
If they are all running on 5V, you can freely mix AC, ACT, HC and HCT.
How many gates does IC 7410 have?
3
Number of gate or circuit : 3.
Is HC a TTL?
HCT outputs are similar to the HC family. TTL output voltages and HC input voltages are incompatible, especially between the TTL high-level output voltage (VOH) and the HC high-level input voltage (VIH). This problem can be solved in three different ways.
What is the difference between HC and HCT?
The only difference between HCT and HC is the input voltage levels.
What is HC HCT?
CMOS Logic ICs HC/HCT Series is commonly used on a 5 V system power supply and is faster (up to 40 MHz) than the Standard Series TC40xx/TC45xx. This document provides an overview of the product, part numbering method, maximum ratings, electrical characteristics, and measurement methods.
What is difference between 74LS and 74HC?
The 74HC series has a very much higher input impedance than the 74LS, which actually ‘leaks’ a small positive current out of an input pin. It is in the uA range so normally is not an issue. The 74HC series has an output drive current of +/- 25 mA, so with a resistor it can drive LED’s directly.
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 is the difference between 7478 and 74107 chips?
In a few instances, such as the 7478 and 74107, the same suffix in different families do not have completely equivalent logic functions. Another extension to the series is the 7416xxx variant, representing mostly the 16-bit-wide counterpart of otherwise 8-bit-wide “base” chips with the same three ending digits.
What are the manufacturers of small IC chips?
Some of the manufacturers that make these smaller IC chips are: Diodes Incorporated, Nexperia ( NXP Semiconductors ), ON Semiconductor ( Fairchild Semiconductor ), Texas Instruments ( National Semiconductor ), Toshiba . The logic families available in small footprints are: AHC, AHCT, AUC, AUP, AXP, HC, HCT, LVC, VHC, NC7S, NC7ST, NC7SU, NC7SV.
What do the right digits mean in the chip numbers?
The right digits, after the 1G/2G/3G, typically has the same functional features as older legacy chips, except for the multifunctional chips and 4-digit chip numbers, which are unique to these newer families. The “x” in the part number is a place holder for the logic family name. For example, 74x1G14 in “LVC” logic family would be “74LVC1G14”.
How do you write the part number 74ls74?
A few alphabetic characters to designate a specific logic subfamily may immediately follow the 74 or 54 in the part number, e.g., 74LS74 for low-power Schottky. Some CMOS parts such as 74HCT74 for high-speed CMOS with TTL-compatible input thresholds are functionally similar to the TTL part.
