It is a member of the 74LS low-power Schottky logic family, designed for driving bus lines or buffered output applications where high fan-out and noise margin are required. ## Sourcing and availability As a standard 74LS logic device, the 74LS573SC is widely available through the independent distribution channel.","metaTitle":"74LS573SC Bus Driver, Active Lifecycle, Bulk","metaDescription":"74LS573SC bus driver from Fairchild.

For a pin-compatible drop-in, the 74ACT16833DL is a different logic family (ACT) and not a direct functional equivalent without verifying supply voltage and drive characteristics. The 74LS574 is a registered (edge-triggered) flip-flop version of the same latch function — the 74LS573 is transparent, the 74LS574 is clocked. A direct replacement should match the 74LS573's latch enable and three-state output architecture."},{"question":"Can I replace 74LS573SC with 74LS373?","answer":"The 74LS373 is functionally similar (octal D-type transparent latch with three-state outputs), but the pinout differs. The 74LS573 uses a 20-pin DIP/SOIC with the latch-enable and output-enable on the opposite side of the package compared to the 74LS373. They are not pin-compatible without a PCB layout change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/74LS573SC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/74LS573SC when reusing this data.
