The Texas Instruments SN74LS21D is a dual 4-input AND gate integrated circuit. It is designed for standard 5V logic systems and offers TTL compatible inputs and outputs. Each of the two independent gates requires four inputs to produce a high output.
Key electrical specifications include a supply voltage range of 4.75V to 5.25V, a maximum propagation delay of 20ns at 5V and 15pF, and input logic levels of ≤ 0.8V for low and ≥ 2V for high. The device provides an output current of 400µA high and 8mA low.
Packaged in a 14-pin SOIC surface-mount case with a width of 3.90mm, the SN74LS21D is suitable for automated PCB assembly. It operates within a temperature range of 0°C to 70°C. This component is ideal for digital logic circuits requiring 4-input AND gate functionality in a compact surface mount format.
Applications include digital logic designs, data processing, control systems, and combinational logic circuits that require multiple input AND functions. It is suitable for consumer electronics, industrial logic controllers, and embedded systems operating at 5V TTL logic levels.
