January 1999 File Number 1719.5
QMOS 8 x 8 x 1 Crosspoint Switches with
Memory Control
The CD74HC22106 is a digitally controlled analog switch
which utilize silicon-gate CMOS technology. The
CD74HC22106 features CMOS input-voltage-level
compatibility.
The Master Reset has an internal pull-up resistor and is
normally used with a 0.1µF capacitor. During power up all
switches are automatically reset. The crosspoint switches
will reset with MR = 0 even if CE is high. A 6-bit address
through a 6 line to 64 line decoder selects the transmission
gate which can be turned on by applying a logic ONE to the
DATA input and logic ZERO to the STROBE. Similarly, any
transmission gate can be turned OFF by applying a logic
ZERO to the DATA input while strobing the STROBE with a
logic ZERO.
The CE pin allows the crosspoint array to be cascaded for
matrix expansion in both the X and Y directions.
