MC671L

Dual 3-Input NAND Gate with Power Strobe, belonging to the vintage Motorola High-Threshold Logic (MHTL) family. Operating from a specialized 15V supply rail, it is engineered with an exceptionally wide internal input noise immunity threshold (typically 5V) specifically designed to deliver error-free logical tracking and command routing inside severe, electrically noisy industrial automation machinery control panels and heavy-duty relay environments, housed in a standard 14-pin through-hole ceramic or plastic dual in-line (DIP) package layout. Manufactured by Motorola. [1]
