Is there 3-input AND gate?
With a single-input gate such as the inverter or buffer, there can only be two possible input states: either the input is “high” (1) or it is “low” (0). A three-input gate has eight possibilities (000, 001, 010, 011, 100, 101, 110, and 111) for input states.
Can OR gate have 3 inputs?
Like the AND gate, the OR function can have any number of individual inputs. However, commercial available OR gates are available in 2, 3, or 4 inputs types. Additional inputs will require gates to be cascaded together for example.
What is a 74LS00 IC?
74LS00 is NAND gates-based IC. It has 14 pins which all connected with 4 NAND gates. Due to the NAND gate known as universal gate, 74LS00 can be converted into OR and NOT gate easily. The IC comes in three packages, SOIC, PDIP, and SOP.
What is the use of 74LS32 gate?
This gate is mainly used in applications where there is a need for mathematical calculations. Here we are going to use 74LS32 chip for demonstration, this chip has 4 OR gates in it.
Can a 74LS output drive a 4000 or 74HC output?
A 74LS output cannot reliably drive a 4000 or 74HC input unless a ‘pull-up’ resistor of 2.2k is connected between the +5V supply and the input to correct the slightly different logic voltage ranges used. Note that a 4000 series output can drive only one 74LS input.
What is the 74ls11 IC?
The 74LS11 IC has a wide range of working voltage, a wide range of working conditions, and directly interfaces with CMOS, NMOS, and TTL. The output of the IC always comes in TTL which makes it easy to work with other TTL devices and microcontrollers.
What is the difference between a Schottky 74 and a 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 74 series is often still called the ‘TTL series’ even though the latest ICs do not use TTL!
