MITSUBISHI 〈DIGITAL ASSP 〉 〉 MITSUBISHI 〈DIGITAL ASSP M66261FP M66261FP 6 CROSSPOINT × 5 CROSSPOINT SWITCH MIXING FUNCTION 6×5 SWITCH withwith MIXING FUNCTION DESCRIPTION The M66261 is an integrated circuit consisting of a 6 × 5 cross point switch capable of selecting 30 analog switches with mixing registance respectively by serial control inputs. Using the M66261 with an external standard Op-Amp, 6 analog input signals can be mixed and output to any of 5 outputs freely by serial control inputs. FEATURES High noise margin ......................... Schmidt trigger circuit built in CKS and LE Switching and mixing function possible with standard OpAmp. Excellent crosstalk characteristic .......................... –90dB [fIN = 3kHz, VIN = –10dBV] (typ.) Line backup function provided in case of a power failure ............................................... (Effective when RD is “L.”) Power supply pins for control circuit (V CC ) and for crosspoint switch circuit (VCC(switch)) are provided separately. APPLICATION Line switching with mixing function of telephone and communication equipments.
