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 out-
puts freely by serial control inputs.
FEATURES
• High noise margin
......................... Schmidt trigger circuit built in CKS and LE
• Switching and mixing function possible with standard Op-
Amp.
• 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 (VCC) and for
crosspoint switch circuit (VCC(switch)) are provided sepa-
rately.
APPLICATION
Line switching with mixing function of telephone and commu-
nication equipments.
