TDK Semiconductor’s 75T2089/2090/2091 are complete Dual-Tone Multifrequency (DTMF) Transceivers that can both generate and detect all 16 DTMF tone-pairs.These ICs integrate the performance-proven 75T202 DTMF receiver with a DTMF generator circuit.The DTMF receiver electrical characteristics are identical to the standard 75T202 device characteristics.The DTMF generator provides performance similar to the Mostek MK5380, but with an improved (tighter) output amplitude range specification and w
