SN7460N expander by Texas Instruments. The chip that time forgot ! Ok, so a bit rare, as these 10 chips are the first to be found in five years, and 2 million + chips... so it's fair to say that they don't come along that often. Download Texas Instruments SN7460N datasheet: Status: RNOS (Rare New Old Stock) DC: 1968 (yes, correct that's 1968 - see photo) Individually tested components: YES It's not normal for us to sell chips of this age, however, these are in perfect condition, and fully tested on a ABI chipmaster and also our much trusted Retro Chip Tester (RCT). Someone, somewhere in a universe far far away, will be pleased to have found these. RoHS compliant: No ** for collectors we also have some simply marked 10-60 DC: 803 ... just ask **
