Power And Operating Modes

• Active current: Not characterized in seed; extract active current from datasheet tables.
• Sleep / standby current: Not characterized in seed; extract sleep/standby current from datasheet tables.
• Supply rails: Not characterized in seed; capture allowed supply rail range from datasheet.
• Notes: Seed values are search hints only. Verify power modes, rail limits, startup requirements, and reference design passives from the datasheet.

Procurement Classification

• JLC class: Extended Part
• JLC note / assembly basis: EasyEDA/JLC verified board-safety/ESD expansion seed for interfaces not yet covered (Ethernet magjack, RS-485/RS-232 bus)
• Assembly status: jlc_extended
• Price-break table: Not captured in seed. Store only timestamped price-break snapshots when intentionally refreshed.
• Live stock: intentionally not stored as durable selection data; refresh externally before ordering.

• Datasheet-derived notes: Not extracted yet. Use PDF extraction to fill power modes, absolute maximums, pin functions, package variants, and reference design requirements.

Selection Notes

• Good for: reuse when package, electrical ratings, footprint, and assembly class match the project constraints
• Avoid when: Not captured yet.
• Known layout constraints: Verify package land pattern, decoupling requirements, thermal pad, RF keepouts, crystal routing, and boot straps from the datasheet.
• Equivalent search hints: match category rs485-esd-array, interfaces rs485, package SOT-23, and EasyEDA footprint UUID 18f92042a8ba46109ed61a02a6753de7.
