Logic Function: Each 4-input AND gate performs the logical AND operation on its four inputs. The output is high only when all four inputs are high.
Low Power Schottky (LS) Technology: The LS designation indicates that it uses Low Power Schottky technology, providing a good balance between speed and power consumption.
Operating Voltage: The typical operating voltage for the SN74LS21N is in the range of 4.75V to 5.25V.
High-Speed Operation: LS TTL devices are known for their relatively high-speed operation compared to standard TTL.
Propagation Delay: Propagation delay is the time it takes for a change at the input to result in a change at the output. This parameter is critical in applications where timing is important.
Standard 14-Pin DIP Package: The SN74LS21N is typically available in a standard 14-pin DIP (Dual Inline Package), a common packaging format for integrated circuits.
Temperature Range:
The typical operating temperature range for the SN74LS21N is 0°C to 70°C.
