Description
The MT8804A is a CMOS/LSI 8 x 4 Analog Switch Array incorporating control memory (32 bits), decoder and digital logic level converters. This circuit has digitally controlled analog switches having very low “ON“ resistance and very low “OFF” leakage current. Switches will operate with analog signals at frequencies to 40 MHz and up to 15.0Vp-p. A “HIGH“ on the Master Reset input switches all channels “OFF“ and clears the memory. This device is ideal for crosspoint switching applications.
