BCT4221 USB2.0 Hi-Speed Switches BCT4221 USB2.0 Hi-Speed Switches GENERAL DESCRIPTION FEATURES The BCT4221 is a high bandwidth, fast double-pole double-throw (DPDT) analog switch. Its wide bandwidth and low bit-to-bit skew allow it to pass high-speed differential signals with good signal integrity. Each switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. Industry-leading advantages include a propagation delay of less than 250ps, resulting from its low channel resistance and low I/O capacitance. Its high channel-to-channel crosstalk rejection results in minimal noise interference.      VCC Operating Range: 2.7V-5.5V Analog Signal Range: 0 to VCC -3dB Bandwidth: 720MHz Off Isolation:-38dB @250MHz Crosstalk Rejection:- 38dB @250MHz     ON-Resistance:6Ω Typical Extended Temperature Range: –40°C to 85°C Green QFN2.0X1.5-10L packages ESD:HBM 8000V The BCT4221 is available in Green QFN2.0X1.5-10L packages.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. CAUTION This integrated circuit can be damaged by ESD if you don’t pay attention to ESD protection. Broadchip recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. Broadchip reserves the right to make any change in circuit design, specification or other related things if necessary without notice at any time.
