1. What is a 74HC series?

High speed, low power logic devices from the 74HC series using CMOS technology. Many current devices, like the 74TTL, 74STTL, and 4000 series, are pin compatible with the new devices.


2. What is difference between 74LS and 74HC?

Transistor to transistor logic is used in the 74LS. uses Shottky transistors to increase switching speeds and decrease the amount of stored charge compared to traditional bipolar transistors. The 74HC employs MOSFET engineering. can therefore function with a wider range of voltages.


3. What type of IC is 7400?

The IC 7400 is a high-performance, high-density, high-speed serial transceiver that provides an interface between a host computer and the electronics subsystem of an automobile. The IC 7400 family features integrated power management with low standby power consumption. The IC 7400 family also offers advanced security features such as advanced Error Detection And Correction (EDAC), programmable configuration registers, Access Control Lists (ACL), environmental monitoring, remote access and diagnostics.


4. Is 74HC a TTL or CMOS?

The 74HC/HCT193 is a high speed Si Gate CMOS device compatible with Low Power Schottky TTL (LSTTL). A single logic gate on a CMOS chip can consist of just two FETs, while  a logic gate on a TTL chip has quite a few parts, as it requires additional components such as resistors. CMOS circuits are  used in NAND NOR gates, whereas standard TTL gates use NAND gates.
