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.
  • ESD support 2KV HBM.
  • The CH440, CH442, and CH444 provide global enable pins, and the multi-channel analog switches can uniformly enable and switch.
  • Support 5V power supply voltage and 3.3V power supply voltage and even 2.5V power supply voltage, low static power consumption.
  • CH440 and CH444 are available in SOP-16 or TSSOP-16 lead-free packages, CH442 is available in MSOP-10 lead-free package, and CH443 is available in SC70-6L (SOT-363) lead-free package, compatible with RoHS.
