For detailed electrical characteristics, refer to the official **ZTX datasheet**.

Application Scenarios & Design Considerations

FET BIAS CONTROLLER WITH POLARISATION SWITCH AND TONE DETECTION

Alternative Part Number

  • LM317LZ --: Widely available adjustable linear regulator in TO-92, a common substitute for Zetex regulator parts with similar function and package.
  • TL783CKC --: High-voltage adjustable linear regulator offering comparable regulation behavior and a through-hole package option.
  • LT317AT --: Precision adjustable regulator with similar electrical role and TO-220 package, suitable as a functional replacement.
  • MAX232ECPE --: Widely available RS-232 transceiver in a 20-pin DIP package, functionally similar to the ZNBG3110Q20 interface function and easy to source as a drop-in style replacement.
  • SP3232ECP --: Pin-compatible 20-pin DIP RS-232 transceiver with comparable supply voltage and data-rate ratings, offering a different series prefix for clear distinction from the original.
  • ST232CN --: Low-cost 20-pin DIP RS-232 driver/receiver with similar electrical characteristics, suitable as a third-source alternative when the first two are unavailable.
