FS (US) misc. ICs/connectors/supplies, pay shipping only
« on: June 03, 2023, 05:43:20 pm »
I've inherited a lot of ICs over time from old lab stock being thrown away, etc., and while a lot of it is useful, I've decided to draw the line at TTL "original" 74-series logic: just don't have the time to deal with the obnoxiously high power consumption of these when there's plenty of LS/HC/AC to be used instead.

So if anyone wants some of these, I'm happy to send them to you for only the price of shipping (probably in the ballpark of $10): US only, international shipping gets complicated quickly.  Might be useful for direct replacements in old equipment, decapping, historical stuff, whatever else (many of these have date codes from the 70's, ask and I can check for you).  Strong preference for sending a whole tube or set of one part number at a time, rather than 1 or 2 of a part that I have 5 of.  Request as much as you want, otherwise whatever's left is going into e-waste next time I move.

The "original" 7400-series ICs in this post are taken; see below for more ICs & connectors

Oh - now there's a throw-back!

I can still remember, before the days of Dick Smith, sending mail order to the USA for these - paid by an international bank cheque made out to the Chemical Bank New York, New York.

Still have some ... somewhere.

I'd be tempted to put my hand up for the lot - but it's probably safer if I don't  ;D ... and I'm in Australia, so that puts a damper on the idea.

More to add to the list, that is not old 74-series logic.  The quantities (1x, 2x, 3x, etc.) are what I have available:

ICs, modern
Microchip MCP73831T-2AC, 3x LiIon (4.2V) linear charge controller (SOT-23-5)
Texas Instruments PCM5100 & PCM5102 sample kit (1 each), Audio stereo I2S DACs w/PLL, SMT
Analog Devices AD790, 7x Analog comparator with latch, 45ns, SOIC
Atmel AT86RF230-ZU, 1x Zigbee/802.15.4 RF transceiver, QFN-32
Melexis US1881, 4x Hall-effect sensor, digital output, latching

ICs, old and/or rare

AMP   204351-1, ~23x D-sub machined contact, female, solder: New in original packaging
(unknown) ~33x D-sub machined contact, male, solder: New and unused in bag, bag opened
AMP rectangular connector housings (marked with part numbers), assortment, 2.54 mm/0.1” pitch single-row: Unused
(unknown) SMC coaxial connectors, assorted cable-mount parts: Unused
(unknown) ~800x Ethernet cable boots, variety of colors: Unused
(unknown) Ethernet cable metal strain relief pieces, bag: Unused

(unknown) 9x IEC 320 C5 power cables, marked “3-Pin Notebook 6 ft”: New in original packaging

Hirose FX8-120P-SV1(91), 26x Mezzanine PCB connector SMT, 120-pos 0.6 mm pitch: New in original packaging, bag & tube opened

There's also 5x ±15V @ 0.4A linear AC-DC power supplies: Condor HAD15-0.4-A+G and Power-One HAD15-0.4-A.  These are heavier and so would cost more to ship (probably at least $20).
