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 SOP16 or TSSOP16 lead-free packages, CH442 is available in MSOP10 lead-free package, and CH443 is available in SC70-6L (SOT363) lead-free package, compatible with RoHS.
