WCH CH446Q

CH446Q is an 8x16 matrix analog switch chip. CH446Q contains 128 analog switches, which are distributed at each cross point of 8x16 signal channel matrices. Each analog switch can be turned on or off independently, so as to realize arbitrary routing of 8x16 signal channel. CH446X is a 5x24 matrix analog switch chip. CH446X contains 120 analog switches, which are distributed at each cross point of 5x24 signal channel matrices. Each analog switch can be turned on or off independently, so as to realize arbitrary routing of 5x24 signal channel.

• CH446Q has 128 built-in independent analog switches, which are distributed at each cross point of 8x16 signal channel matrices.
• CH446X has 120 built-in independent analog switches, which are distributed at each cross point of 5x24 signal channel matrices.
• CH446Q supports 7-bit parallel address input and is compatible with existing similar products.
• Support serial address shift input to save pins.
• Support 4-12V single supply voltage, support +5V and -7V dual supply voltage.
• When the voltage difference of positive and negative power supply is 12V, the on resistance Ron is 65Ω to the maximum, and △Ron is not more than 10Ω.
• Pure CMOS process, low static power.
• Adopt LQFP-44 lead-free package, be compatible with RoHS, provide the conversion board for converting into PLCC44 package.
