CH446X

Overview

The CH446Q is an 8×16 matrix analog switch chip. The CH446Q contains 128 analog switches which distributed at each intersection of the 8×16 signal path matrix, each analog switch can be turned on or off independently, enabling arbitrary routing of 8×16 signal paths.

The CH446X is a 5×24 matrix analog switch chip. The CH446X contains 120 analog switches distributed at each intersection of the 5×24 signal path matrix. Each analog switch can be turned on or off independently, enabling arbitrary routing of 5×24 signal channels.

Features

• CH446Q has built-in 128 independent analog switches, distributed at each intersection of the 8×16 signal path matrix.
• CH446X has built-in 120 independent analog switches, distributed at each intersection of the 5×24 signal path matrix.
• The CH446Q supports 7-bit parallel address input and is compatible with existing products.
• Supports serial address shift input and saves pins.
• Supports single supply voltages from 4V to 12V and supports dual supply voltages of +5V and -7V.
• When the positive and negative supply voltage difference is 12V, the on-resistance Ron is at most 65Ω, and ΔRon does not exceed 10Ω.
• Pure CMOS process with low static power.
• The LQFP44 is available in a lead-free package, compatible with RoHS, providing a conversion board that is converted to a PLCC44 package.
