M-985-01P Datasheet (Clare Inc.) - Precise Call Progress and Special Information Tone Generator

M-985-01P, Precise Call Progress and Special Information Tone Generator

The M-985-01 is an integrated circuit precise tone detector for call progress and special information tones (SIT), as defined by CCITT.

The use of integrated circuit techniques allows the M-985-01 to pack the eight filters for call progress detection into a single 22-pin DIP or a 20-pin SOIC.
