As I use surface-mount devices almost exclusively nowadays, the through-hole chips are pretty much surplus to requirements so I'm having a clearout. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTHESE ARE ALL THROUGH-HOLE DEVICES SO ARE BREADBOARD AND DIY-FRIENDLY\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis is an incomplete list, and may be added to in future - stock levels will vary wildly. Take your pick from:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTL072\/TL082 (DIP-8)\u003c\/strong\u003e - dual op-amp. Myriad different uses (buffers, comparators, oscillators etc.)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTL074\/TL084 (DIP-14)\u003c\/strong\u003e - quad op-amp. As above, but twice as many.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLM13700 (DIP-16)\u003c\/strong\u003e - dual operational transconductance amplifier (OTA). A very versatile piece of kit - can be use to make filters, VCOs and VCOs. The datasheet has a load of useful example circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNE555\/SA555 (DIP-8)\u003c\/strong\u003e - the classic timer IC. Surprisingly versatile ...\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCD4017 (DIP-16)\u003c\/strong\u003e - 10-stage counter; the ideal chip for building sequencers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCD40106 (DIP-14)\u003c\/strong\u003e - Hex Schmitt trigger inverter. Another mind-bogglingly useful chip that can be used for oscillators and a whole lot more. People have built entire \u003cem\u003esystems\u003c\/em\u003e around these ...\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e6N138 (DIP-8) \u003c\/strong\u003e- Darlington optocoupler. Very useful for MIDI-oriented circuits.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAll of these ICs were sourced from suppliers in the UK, so they're all legit - most were manufactured by the likes of TI, STMicro and NXP with the occasional outlier (Renesas, Fairchild etc.). You can find datasheets using your favourite search engine or similar.\u003c\/p\u003e\n\u003cp\u003eIf you require a large number of any particular IC, let me know and I might be able to accomodate you (I have a \u003cem\u003elot\u003c\/em\u003e of TL074\/084s, for example ...). I also have a few surface-mount ICs available - mostly op-amps.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNOTE: \u003c\/strong\u003eif a particular IC is shown is out of stock, chances are that I will have it but I haven't got around to counting how many I actually have. Drop me an email letting me know what you're after and I can let you know whether or not there's a genuine lack of stock or it's just me being lazy ....\u003c\/p\u003e","brand":"York Modular","offers":[{"title":"TL072\/TL082","offer_id":57558650257786,"sku":null,"price":0.25,"currency_code":"GBP","in_stock":true},{"title":"TL074\/TL084","offer_id":57558650290554,"sku":null,"price":0.5,"currency_code":"GBP","in_stock":true},{"title":"LM13700","offer_id":57558650323322,"sku":null,"price":1.0,"currency_code":"GBP","in_stock":true},{"title":"NE555\/SA555","offer_id":57558650356090,"sku":null,"price":0.5,"currency_code":"GBP","in_stock":true},{"title":"CD40106","offer_id":57558650388858,"sku":null,"price":0.5,"currency_code":"GBP","in_stock":false},{"title":"CD4017","offer_id":57558650421626,"sku":null,"price":0.5,"currency_code":"GBP","in_stock":false},{"title":"6N138","offer_id":57558661333370,"sku":null,"price":0.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0274\/7115\/1213\/files\/Three_IC_circuit_chips.jpg?v=1794521127","url":"https:\/\/www.yorkmodular.co.uk\/products\/cmos-ics-op-amps-and-other-chippery","provider":"York Modular","version":"1.0","type":"link"}
