Internally it contains two elements: one 2-bit and one 4-bit, giving a total of six inverting channels. The 3-state output lets you connect multiple buffers to a common bus — when the output enable is inactive, the pin goes high-impedance and doesn't load the line. ## Output drive — 2.6 mA high, 24 mA low The rated output drive is 2.6 mA sourcing (logic high) and 24 mA sinking (logic low). That asymmetric ratio is typical for LS TTL: the low-level sink is the stronger leg, so the part is best at pulling a bus line low through a pull-up resistor. Fan-out to standard LS loads is fine, but don't expect to drive a 50 Ω backplane directly on the high side. ## Package and rework — 16-DIP, through-hole The 16-pin DIP (0.300\" row spacing) is a through-hole part — easy to hand-solder, easy to pull with a desoldering station or even a solder sucker. No thermal pad, no hidden leads; it's about as rework-friendly as a logic IC gets. The supplier device package is 16-PDIP. It's a mature 74LS part that has been in production for decades, and Texas Instruments continues to manufacture it.","metaTitle":"SN74LS368AN Texas Instruments 74LS Inverting Buffer, 3-State","metaDescription":"SN74LS368AN Texas Instruments inverting buffer with 3-state output, 4.75V-5.25V supply, 2.6mA/24mA drive, 0°C to 70°C, 16-DIP.","metaKeywords":null},"attributes":{"series":"74LS","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"74LS","Package":"Tube","Logic Type":"Buffer, Inverting","Output Type":"3-State","Mounting Type":"Through Hole","Package / Case":"16-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Number of Elements":"2","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"16-PDIP","Current - Output High, Low":"2.6mA, 24mA","Number of Bits per Element":"2, 4 (Hex)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.87","priceTiers":[{"qty":1,"price":"$1.87000","currency":"USD"},{"qty":10,"price":"$1.68300","currency":"USD"},{"qty":25,"price":"$1.58720","currency":"USD"},{"qty":100,"price":"$1.35240","currency":"USD"},{"qty":250,"price":"$1.26988","currency":"USD"},{"qty":500,"price":"$1.11114","currency":"USD"},{"qty":1000,"price":"$0.92066","currency":"USD"},{"qty":2500,"price":"$0.89850","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a64c34e8eb4d0993c2a29d0f83e638d7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74LS368AN/alternatives.json"},"ai":{"faq":[{"question":"Is the SN74LS368AN obsolete?","answer":"Texas Instruments continues to manufacture this part."},{"question":"What is the SN74LS368AN equivalent?","answer":"The SN74LS645-1N is a different logic type (non-inverting transceiver) and is not a direct functional equivalent.
