The 2 µs access time sets the timing for the 1-Wire read/write slots; at standard 15 µs time slots this part has margin, so no bus-timing tweaks needed when dropping it into an existing 1-Wire network. Memory is organized as 256 x 16 bits, which is enough for a few dozen calibration constants or a 512-byte configuration block — not for firmware images, but exactly the size you want for a trim pot replacement or a product-ID string. Supply range spans 2.8V to 5.25V, so it runs cleanly on a 3.3V or 5V logic rail without a level translator. The -40°C to 85°C temperature grade covers outdoor enclosures, factory-floor gear, and under-hood cabin applications that don't see engine-block heat. ## Package and mounting — through-hole simplicity The DS24B33+ comes in a TO-92-3 through-hole package (TO-226-3, TO-92-3 TO-226AA). That three-lead TO-92 is the same footprint as a standard small-signal transistor or a DS18B20 temperature sensor, so it hand-solders easily and fits on a perfboard or a two-layer PCB with no fine-pitch concerns. The through-hole mount also makes it a practical choice for retrofit or repair work where you're replacing a socketed part. ## Lifecycle and sourcing reality The DS24B33+ carries an Active lifecycle status and is ROHS3 compliant.","metaTitle":"Maxim DS24B33+ EEPROM, 4Kbit 1-Wire TO-92-3, 2 µs Access","metaDescription":"Maxim DS24B33+ 4Kbit EEPROM with 1-Wire interface, 2 µs access time, 2.8V-5.25V supply, -40°C to 85°C.

Functionally identical — same 4Kbit 1-Wire EEPROM, same TO-92-3 package, same 2 µs access time, same 2.8V-5.25V supply range. The '+' suffix indicates ROHS compliance.

The supply voltage range of 2.8V to 5.25V means the DS24B33+ operates directly on a 5V logic rail without any level shifting. The 1-Wire bus interface is designed to work with standard 5V logic levels, and the 2 µs access time is compatible with typical 1-Wire timing at 5V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/DS24B33","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/DS24B33 when reusing this data.
