It packs one element with eight bits per element in a through-hole 20-PDIP package, running on a 4.5 V to 5.5 V supply. The 30 MHz clock frequency and 14 ns propagation delay at 5 V, 50 pF give it the timing headroom for bus-oriented storage and register applications in commercial-temperature (0°C to 70°C) environments. ## 30 MHz clock and 14 ns propagation delay — timing margin for synchronous buses The 30 MHz clock and 14 ns propagation delay at 5 V, 50 pF provide timing margin for synchronous buses. The 18 mA quiescent current is the ALS logic draw at idle. ## Output drive: 2.6 mA source, 24 mA sink The tri-state inverted outputs can source 2.6 mA and sink 24 mA per pin. The 24 mA sink capability is the stronger side — it drives standard TTL loads and LED indicators directly, but the 2.6 mA source limit means the high-level output voltage will droop if the fan-out exceeds a few LSTTL inputs. For bus applications, the tri-state control lets multiple devices share a data line without contention. ## Lifecycle and supply posture The SN74ALS576BN carries an active lifecycle status with ROHS3 compliance.","metaTitle":"SN74ALS576BN 74ALS D-Type Flip-Flop, 30 MHz, 20-PDIP","metaDescription":"TI SN74ALS576BN 8-bit D-type flip-flop, 30 MHz clock, 14 ns propagation delay, tri-state inverted outputs, 4.5-5.5 V supply, 20-PDIP, active status.","metaKeywords":null},"attributes":{"series":"74ALS","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"D-Type","Series":"74ALS","Package":"Tube","Function":"Standard","Output Type":"Tri-State, Inverted","Trigger Type":"Positive Edge","Mounting Type":"Through Hole","Package / Case":"20-DIP (0.300\\\", 7.62mm)","Clock Frequency":"30 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Elements":"1","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"20-PDIP","Current - Quiescent (Iq)":"18 mA","Current - Output High, Low":"2.6mA, 24mA","Number of Bits per Element":"8","Max Propagation Delay @ V, Max CL":"14ns @ 5V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.70000","currency":"USD"},{"qty":10,"price":"$1.53100","currency":"USD"},{"qty":25,"price":"$1.44440","currency":"USD"},{"qty":100,"price":"$1.23050","currency":"USD"},{"qty":250,"price":"$1.15540","currency":"USD"},{"qty":500,"price":"$1.01098","currency":"USD"},{"qty":1000,"price":"$0.83766","currency":"USD"},{"qty":2500,"price":"$0.81750","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f7fdaafa446e5811496dce012e5ed000.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output type of SN74ALS576BN?","answer":"The SN74ALS576BN has tri-state, inverted outputs.
