Additional Details

The M74AS21P typically comes in a 14-pin DIP (Dual In-line Package). Each of the two AND gates operates independently, taking four inputs and producing a single output that is the logical AND of the inputs. The output is HIGH only when all inputs are HIGH; otherwise, the output is LOW. The AS technology ensures high-speed performance, making it suitable for demanding digital applications. The device's TTL compatibility allows it to interface easily with other TTL devices in a system. Its high noise immunity also ensures reliable operation in noisy environments.
