MS8870 : 18 PIN DIP PACKAGE
Description
The MS8870 is a complete DTMF receiver integrating
both the bandsplit filter and digital decoder functions,
fabricated in double poly technology and is pin and
function compatible with MITEL8870. The filter section
uses switched capacitor techniques for high and low group
filters; the decoder uses digital counting techniques to
detect and decode all 16 DTMF tone-pairs into a 4-bit code.
External component count is minimized by on chip
provision of a differential input amplifier, clock oscillator
and latched 3-state bus interface.
