0V to 15.
0V operation Low crosstalk between switches Low on resistance: 90Ω (typ.
) at 13V Matched switch characteristics Switches frequencies up to 40MHz ISSUE 2 October 1989 Ordering Information MT8804AC 24 Pin Ceramic DIP MT8804AE 24 Pin Plastic DIP MT8804AP 28 Pin PLCC -40° to 85°C 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.
