Description
The MT8804A is a CMOS/LSI 8 x 4 Analog Switch
Array incorporating control memory (32 bits), deco-
der 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.
