DESCRIPTION
The M66260 is an integrated circuit consisiting of a 8 × 4
cross point switch capable of selecting 32 analog switches
with mixing registance respectively by serial control inputs.
Using the M66260 with an external standard Op-Amp, 8 ana-
log input signals can be mixed and output to any of 4 outputs
freely by serial control inputs.
FEATURES
• Serial data input type
• Switching and mixing function possible with standard Op-
Amp.
• Switch matrix can be extended to 8 × 8 or 8 × 12 by com-
bining 2 or 3 ICs in parallel.
• Excellent crosstalk characteristic
.......................... –90 dB [f = 3 kHz, VIN = –10dBV] (typ.)
APPLICATION
Line switching with mixing function of telephone and commu-
nication equipments.
FUNCTION
Serial data input A is the data input of the first step of 32 BIT
SHIFT REGISTER and when latch enable input LE is “L”, the
signal of A shifts shifting registers one by one when shift
clock input CKs changes from “L” to “H”, in units of 32 bits.

The 32 bits are stored into LATCH CIRCUIT in parallel when
latch enable LE changes from “L” to “H”.
Analog switches come on in a low-impedance state when
the output of the corresponding latch circuit is “H”. They
come off in a high-impedance stage when the output of the
corresponding circuit is “L”.
