It usually is, but input thresholds and drive current differ between the families, and a circuit that relied on LS-level loading may not behave the same way. For the HM62256 SRAM, pin-compatible 32K×8 devices exist from several makers, but access time and standby current vary — check both before substituting in a timing-critical design.\u003c\/p\u003e","products":[{"product_id":"hd74ls109ap","title":"HD74LS109AP DIP16 IC Chip New in Stock Electronic Components","description":"\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e HD74LS109AP\u003c\/p\u003e\u003cp\u003eHD74LS109AP DIP16 IC Chip New in Stock Electronic Components\u003c\/p\u003e\u003cp\u003eMOQ: 50 | Original \u0026amp; new stock electronic components.\u003c\/p\u003e\u003cp\u003eContact us for pricing, availability and quotes.\u003c\/p\u003e","brand":"Hitachi","offers":[{"title":"Default Title","offer_id":71213128941821,"sku":null,"price":0.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0838\/6202\/8541\/files\/Hf46ab26bfc884f579fe3432b96b14bb4G.webp?v=1788150518"},{"product_id":"tmcmb1c226mtr","title":"TMCMB1C226MTR SMD IC Chip New in Stock Electronic Components","description":"\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e TMCMB1C226MTR\u003c\/p\u003e\u003cp\u003eTMCMB1C226MTR SMD IC Chip New in Stock Electronic Components\u003c\/p\u003e\u003cp\u003eMOQ: 500 | Original \u0026amp; new stock electronic components.\u003c\/p\u003e\u003cp\u003eContact us for pricing, availability and quotes.\u003c\/p\u003e","brand":"Hitachi","offers":[{"title":"Default Title","offer_id":71213491290365,"sku":null,"price":0.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0838\/6202\/8541\/files\/H45506c88ef1a45ba9342899b5320cb027.webp?v=1788153989"},{"product_id":"hd74ls161ap","title":"HD74LS161AP DIP IC Chip New in Stock Electronic Components","description":"\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e HD74LS161AP\u003c\/p\u003e\u003cp\u003eHD74LS161AP DIP IC Chip New in Stock Electronic Components\u003c\/p\u003e\u003cp\u003eMOQ: 100 | Original \u0026amp; new stock electronic components.\u003c\/p\u003e\u003cp\u003eContact us for pricing, availability and quotes.\u003c\/p\u003e","brand":"Hitachi","offers":[{"title":"Default Title","offer_id":71213670301949,"sku":null,"price":0.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0838\/6202\/8541\/files\/Hfbe77941960647ee8c8ee84c33aaa963o.webp?v=1788156513"},{"product_id":"hm62256blfp-8t","title":"HM62256BLFP-8T SOP28 IC Chip New in Stock Electronic Components","description":"\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e HM62256BLFP-8T\u003c\/p\u003e\u003cp\u003eHM62256BLFP-8T SOP28 IC Chip New in Stock Electronic Components\u003c\/p\u003e\u003cp\u003eMOQ: 50 | Original \u0026amp; new stock electronic components.\u003c\/p\u003e\u003cp\u003eContact us for pricing, availability and quotes.\u003c\/p\u003e","brand":"Hitachi","offers":[{"title":"Default Title","offer_id":71213783351549,"sku":null,"price":1.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0838\/6202\/8541\/files\/Hd1bb7f12593b475c9b85083d637bcbef5.webp?v=1788158911"},{"product_id":"tmcp0j106mtrf","title":"TMCP0J106MTRF SMD IC Chip New in Stock Electronic Components","description":"\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e TMCP0J106MTRF\u003c\/p\u003e\u003cp\u003eTMCP0J106MTRF SMD IC Chip New in Stock Electronic Components\u003c\/p\u003e\u003cp\u003eMOQ: 500 | Original \u0026amp; new stock electronic components.\u003c\/p\u003e\u003cp\u003eContact us for pricing, availability and quotes.\u003c\/p\u003e","brand":"Hitachi","offers":[{"title":"Default Title","offer_id":71214582923517,"sku":null,"price":0.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0838\/6202\/8541\/files\/H7a0183a3e6d347939e6c6646cbc0b6b7z.webp?v=1788167875"},{"product_id":"hd74ls181p","title":"HD74LS181P DIP24 4-Bit Arithmetic Logic Unit IC Chip New in Stock Electronic Components","description":"\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e HD74LS181P\u003c\/p\u003e\u003cp\u003eHD74LS181P DIP24 4-Bit Arithmetic Logic Unit IC Chip New in Stock Electronic Components\u003c\/p\u003e\u003cp\u003eMOQ: 50 | Original \u0026amp; new stock electronic components.\u003c\/p\u003e\u003cp\u003eContact us for pricing, availability and quotes.\u003c\/p\u003e","brand":"Hitachi","offers":[{"title":"Default Title","offer_id":71219767869693,"sku":null,"price":0.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0838\/6202\/8541\/files\/H4d3d8c75f7d74ff8acc803e44c358406w.webp?v=1788237341"}],"url":"https:\/\/yiluda.myshopify.com\/collections\/hitachi.oembed","provider":"易路达","version":"1.0","type":"link"}
