What is the Xinluda XL232Z?

The XL232Z is a +5V-powered RS-232 transceiver from Xinluda with two drivers and two receivers. It uses an integrated dual charge pump and four external 1 uF capacitors to generate RS-232 line voltages from a single +5V supply, supporting data rates up to 120 kbps.

Is the XL232Z a drop-in replacement for the MAX232?

Yes. The XL232Z is pin-compatible with the industry-standard MAX232 family (including MAX232C, MAX232D and ST232 variants) and can serve as a second-source or drop-in replacement in existing SOP-16 RS-232 interface designs.

What package does the XL232Z come in?

The XL232Z is supplied in a 16-pin SOP-16 surface-mount package. The 'Z' suffix in the part number designates the SOP-16 package option in Xinluda's RS-232 family, distinguishing it from the DIP-16 (XD232) and SOP-16K (XL232K) variants.

What external components does the XL232Z require?

The XL232Z requires four external 1 uF capacitors for the charge-pump and reservoir circuitry, plus the +5V supply and ground. No external positive or negative supplies are needed because the charge pump generates the RS-232 line voltages internally.

What is the operating temperature range of the XL232Z?

The XL232Z operates over an industrial temperature range of -40 C to +85 C, making it suitable for industrial and embedded serial communication applications.

Is the XL232Z hard to find, and can Pacific Component Xchange source it?

The XL232Z is a niche Xinluda part with limited authorized-distributor availability. Pacific Component Xchange specializes in sourcing hard-to-find interface and power-management ICs. Submit an RFQ and our team will respond with availability, lead time and pricing for your quantity.
