LS7509 - TONE ACTIVATED TELEPHONE LINE SWITCH CONTROLLERS

Download the LS7509 datasheet PDF. This datasheet also covers the LS7501 variant, as both devices belong to the same tone activated telephone line switch controllers family and are provided as variant models within a single manufacturer datasheet.

Description

The LS7501 - LS7510 are CMOS frequency discriminator circuits designed to respond to a specific frequency TONE signa

Features

  • Circuit activated by Tone with specific Frequency and Time Duration.
  • Frequency and Time Duration values are mask programmable.
  • Small Signal (as low as - 30 DBM) and Digital Level Tone signals accommodated.
  • On-chip active oscillator network and 32,768 Hz Crystal generates timing.
  • Low power consumption.
  • +4.0V to +6V operation (VDD - VSS).
