Texas Instruments SN18G141  
Written by Accutron on 2017-03-10  

The SN18G141 appears to be a Texas Instruments Series SNG logic device. Series SNG is a relatively early TTL logic family, packaged in 14-pin gold-plated military flat-pack carriers. Known part numbering schemes are formatted as SNGxxx in official TI documentation, and Gxxx on the devices themselves. The SN18G141 pictured here is either a SNG variant or a print variation of the SNG141, a quad two-input NAND gate. The date code of this device is eight months earlier than the earliest known SNG devices from other collections.
