Introduction

AI Translation

CH440G, CH440P, CH440R, CH442E, CH443K, CH444G, CH444P, and CH448F are analog switch ICs rated for 5V supply voltage, featuring high bandwidth and low on-resistance, with support for 3.3V or lower supply voltages. CH445P is an analog switch IC rated for 3.3V supply voltage, featuring high bandwidth and low on-resistance, with support for 2.5V or lower supply voltages. CH440G, CH440P, CH440R, and CH445P each contain 4 channels of low-resistance wideband bidirectional 2:1 analog switches, forming a quad-channel 2:1 MUX (QPDT), suitable for 2:1 switching of video or USB signals. CH442E contains 2 channels of low-resistance wideband bidirectional 2:1 analog switches, forming a dual-channel 2:1 MUX (DPDT), suitable for 2:1 switching of video or USB signals. CH443K contains 1 channel of low-resistance wideband bidirectional 2:1 analog switch, forming a single-channel 2:1 MUX (SPDT), suitable for 2:1 signal switching of video and other signals, simple logic gate functions such as AND/OR/NOT, or digital signal level translation between two voltage domains. CH444G and CH444P each contain 2 channels of low-resistance wideband bidirectional 4:1 analog switches, forming a dual-channel 4:1 MUX (DPQT), suitable for 4:1 switching of video or USB signals. CH448F contains a pair of differential signal low-resistance wideband bidirectional 8:1 analog switches, forming a dual-channel 8:1 MUX (DPOT), suitable for 8:1 switching of video or USB signals. Additionally, by combining control of the two-channel global enable pins, a 16:1 MUX can be implemented.

Features

AI Translation
  • Low on-resistance, Ron typical value ~5Ω.
  • High bandwidth, supports video signals, low-speed, full-speed, and high-speed USB signals.
  • Fast switching, Ton/Toff typical value <5nS.
  • ESD protection: 2KV HBM.
  • CH440/CH442/CH444/CH445/CH448 provide a global enable pin for unified enable and switching across multiple analog switch channels.
  • CH448 supports differential signals and provides independent global enable pins for two signal channels.
  • CH448 control signals are independent of supply voltage, supporting 5V, 3.3V, and 2.5V control signals.
  • Wide supply voltage range with low quiescent power consumption. 5V switch ICs support rated 5V supply voltage (5V~2.5V control signals), operable down to 2.5V supply; 3.3V switch ICs support rated 3.3V supply voltage (3.3V~2.5V control signals), operable down to 1.8V supply.
  • Available in SOP16, TSSOP16, QFN16, QFN24, MSOP10, and SOT363 packages, RoHS compliant.
