4 Input And Gate Ic. This enables the use of current limiting resistors to interface inputs to voltages in excess of vcc. 7421 7421 datasheet 7421 dual 4 input and gate buy 7421 ic 7421.
The 74ls20 ic has a wide range of working voltage a wide range of working conditions and directly interfaces with cmos nmos and ttl. Number of input lines 4 input number of output lines 1 output. An and gate is a logic gate that gives a high output only when all its inputs are high.
Semiconductors logic ics logic gates.
An and gate is a logic gate that gives a high output only when all its inputs are high. Features and benefits low power dissipation complies with jedec standard no. The output of the ic always comes in ttl which makes it easy to work with other ttl devices and microcontrollers. The output of the ic always comes in ttl which makes it easy to work with other ttl devices and microcontrollers.
