Single pole double throw low resistance analog switch chip CH440/2/3/4


Overview

The CH442 is a 4-channel low resistance broadband bidirectional analog switch chip. The CH442 includes a 4-channel SPDT single-pole double-throw analog switch with high bandwidth and low on-resistance for switching between video or USB signals.

The CH442 is a dual channel low resistance broadband bidirectional analog switch chip. The CH442 includes a 2-channel SPDT single-pole double-throw analog switch with high bandwidth and low on-resistance for switching between video or USB signals.

The CH443 is a single channel low resistance broadband bidirectional analog switch chip. The CH443 includes a single channel SPDT single-pole double-throw analog switch with high bandwidth and low on-resistance for switching between video or USB signals.

The CH444 is a dual channel low resistance broadband bidirectional analog switch chip. The CH444 includes a 2-channel SPDT single-pole fourth-throw analog switch with high bandwidth and low on-resistance for switching between video or USB signals.

Features

  • Low on-resistance, Ron typical value is 5Ω.
  • High bandwidth, Bw typical value is 550MHz.
  • Supports video signals and supports low speed, full speed and high speed USB signals.
  • Switching fast, Ton/Toff typical value is less than 5nS.
