content: 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(more varied parts added, see below)7400 quad NAND; 9x7402 (74F02) quad NOR; 3x7403 quad NAND open-collector; 3x7404 hex inverter; 6x7406 (DM7406) hex inverter, 30V open-collector outputs; 6x7408 quad NAND; 2x7410 triple 3-input NAND gate; 9x7411 triple 3-input AND gate; 4x7414 (NTE7414) hex Schmitt-trigger inverter; 1x7420 (DM7420) dual 4-input NAND gate; 1x7426 quad 2-input NAND gate with 15 V open-collector outputs; 11x7427 triple 3-input NOR; 1x7430 single 8-input NAND; 2x7432 (TI 74S32) quad 2-input OR; 1x7437 quad 2-input NAND buffer; 12x7438 quad 2-input NAND; 6x7442 (DM7442) BCD to decimal decoder; 1x7443 excess-3 to decimal decoder; 4x7464 (74S64) "4-3-2-2-input AND-OR-Invert gate" (?); 3x7473 dual J-K flip-flop with clear; 6x7474 (DM74S74, N74S74) dual D-FF with preset, clear; 5x7475 (7475) 4-bit bistable latch; 18x7476 (DM7476, 7476PC) dual J-K FF w/preset, clear; 2x7483 4-bit binary full adder; 6x7486 (DM7486, HD7486P) quad 2-input XOR; 2x7490 (7490) div-by-2 + div-by-5 counter; 6x7495 4-bit parallel-in/parallel-out shift register, serial input; 7x7496 5-bit parallel-In/parallel-out shift register, asynchronous preset; 9x74111 dual J-K master-slave flip-flop with data lockout; 3x74138 (74F138) 1-of-8 3-bit decoder/demux, inverting; 1x74155 dual 2-line to 4-line decoder/demultiplexer; 10x74161 (TI SN74161N) 4-bit counter, presettable w/clear; 1x74164 (Signetics) shift register 8-bit serial-in parallel-out; 1x74175 (Signetics) quad D flip-flop, asynchronous clear; 7x74180 9-bit odd/even parity bit generator and checker; 6x74193 (Signetics) 4-bit counter up/down, presettable w/clear; 3x74194 (DM74S194) 4-bit shift register bidirectional; 126xSN15861N dual 4-input NAND, DTL; 3x

content: 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... and I'm in Australia, so that puts a damper on the idea.
