74LS21 Dual 4 Input Positive AND Gate IC

74LS21 is a dual 4-input positive-AND gate IC. This means that it has two independent 4-input AND gates. An AND gate is a logic gate that produces a logic 1 output only when all of its inputs are logic 1. The 74LS21 has a low power consumption, high speed, and wide operating temperature range.

It is a TTL (Transistor-Transistor Logic) IC, which means that it is compatible with other TTL devices. The 74LS21 can be used in a variety of applications, such as digital logic circuits, programmable logic controllers (PLCs), microcontrollers, data acquisition systems, test and measurement equipment, industrial control systems, and consumer electronics.

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.
The 74LS21 is a dual 4-input positive-AND gate integrated circuit (IC) in the 74xx family of logic ICs. It has two independent 4-input AND gates, each of which performs the logic AND function.

The input voltage is 7V, the maximum supply voltage is 7V, and the maximum current allowed to draw through each gate output is 8mA. The outputs are TTL, which makes it easy to work with other TTL devices and microcontrollers. The 74LS21 has a low power consumption, typical rise time of 18ns, typical fall time of 18ns, and operating temperature of 0°C to +70°C.
