74LS21 Dual 4-input AND Gate IC – DIP-14 Package
These devices contain two independent 4-input AND gates The 74LS21 IC package contains two independent positive logic 4-input AND Gates, belonging to the 74XXYY TTL IC series. The 74LS21 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. The IC 74LS21 is smaller in size and it has a much faster speed which makes it reliable in every kind of device. This product is known as SN74LS21NSR, SN74LS21DR, SN74LS21D, SN74LS21NE4, SN74LS21N, SN74LS21NS, 4-bit Bi-directional Shift Register IC, 4-bit Bi-directional Shift Register DIP IC, 74194 IC, 74194 DIP IC, 74LS194 IC, 74LS194 DIP IC.
