Application Scenarios & Design Considerations

Dual stage IF amplifier for cable tuners

Alternative Part Number

  • MT8870DE --: Zarlink/Microsemi inherited Mitel's telecom line; the MT8870 DTMF receiver is a direct functional successor commonly used where SL2009 was applied.
  • CM8870CPE --: CML's CM8870 is a pin-compatible DTMF decoder widely used as a second-source replacement for Mitel SL-series telecom ICs.
  • HT9170D --: Holtek HT9170 is a low-cost DTMF receiver offering similar functionality and is a practical drop-in alternative for legacy SL2009 designs.
  • TPS2009 --: Similar power switch IC with comparable voltage and current ratings, widely available and well documented.
  • MIC2009 --: Pin-compatible power distribution switch offering similar current limiting behavior and package options.
  • AP2009 --: Comparable load switch with similar electrical characteristics, suitable as a drop-in functional replacement.
