Direct access to Shenzhen floor inventory, franchised allocation buffers, and factory bonded stock to resolve line-down shutdowns.
Standard factory-sealed packaging compliant with EIA-481 standards for automated high-speed SMT pick-and-place lines.
High-resolution photos of original reel labels, 2D DataMatrix, and pin coplanarity sent via WhatsApp/Telegram before you release wire payment.
Each I/O can sink 25 mA but source only 100 µA. Drive LEDs or small relays by sinking current from the load to ground, not sourcing from the pin. The push-pull output structure eliminates the need for pull-up resistors on outputs.
Power-On Reset (POR) initialises all I/O registers to a known state when the supply crosses the threshold.
Yes, the PCA8575DB,118 is the same die in a Tape & Reel packaging variant of the base PCA8575. The DB suffix indicates the 24-SSOP package; the,118 suffix specifies the reel format. Pinout and electrical specs are identical — it is a drop-in replacement.
Yes, it provides an interrupt output (INT) that asserts low when any input pin changes state. This allows the host MCU to react to events without polling the I²C bus.
We source PCA8575DB,118 in Tape & Reel (TR) and Cut Tape (CT) formats. Submit an RFQ for current pricing and availability — we confirm both at quote time.
Lead time varies by distributor and order quantity. We quote against your RFQ with the best available lead time from our independent supply network — no fixed number here, but we confirm it at quote.
