The 7.62 mm body width fits standard 0.3-inch DIP sockets and perfboard. If you need to swap it on a prototype board, a desoldering iron or hot-air preheat from the bottom side lifts the part clean without lifting pads. No thermal pad underneath, so no hidden solder joint to worry about. ## Supply voltage and current — what the numbers mean The 1V to 15V supply range covers everything from a single alkaline cell to a 12V rail. The 360 µA quiescent current is roughly one-tenth what a bipolar 555 pulls at the same voltage, so battery-powered designs get real runtime benefit. That low supply current also means less self-heating in the DIP — the part stays cool even in a cramped enclosure. ## Lifecycle and sourcing The TLC551CP carries an Active product status with ROHS3 compliance. No LTB risk for ongoing builds.","metaTitle":"TLC551CP 555-Type Timer/Oscillator, 1.8MHz, 8-DIP","metaDescription":"Texas Instruments TLC551CP 555-type timer/oscillator, single, 1.8MHz max frequency, 1V-15V supply, 360µA quiescent, 8-DIP through-hole, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Type":"555 Type, Timer/Oscillator (Single)","Package":"Tube","Frequency":"1.8MHz","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Current - Supply":"360 µA","Voltage - Supply":"1V ~ 15V","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"8-PDIP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.70000","currency":"USD"},{"qty":10,"price":"$2.42400","currency":"USD"},{"qty":25,"price":"$2.28680","currency":"USD"},{"qty":100,"price":"$1.94850","currency":"USD"},{"qty":250,"price":"$1.82956","currency":"USD"},{"qty":500,"price":"$1.60086","currency":"USD"},{"qty":1000,"price":"$1.32643","currency":"USD"},{"qty":2500,"price":"$1.29450","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b979ccbfda3605e0f5a045ebcbf4c728.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between TLC551CP and NE555?","answer":"The TLC551CP is a CMOS 555-type timer with a 1.8 MHz maximum frequency and 360 µA supply current, versus the bipolar NE555 which typically tops out around 100 kHz and draws several mA. The TLC551CP also operates down to 1V, while the NE555 needs at least 4.5V. Both are 8-pin DIP and pin-compatible for most circuits, but the TLC551CP's lower power and wider voltage range suit battery-powered and higher-frequency designs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TLC551CP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TLC551CP when reusing this data.
