DATASHEET ISL54233 FN7918 Rev.1.00 Wideband Differential 3:1 Multiplexer Dec 12, 2018 The ISL54233 is a single supply differential 3 to 1 multiplexer Features that operates from a single supply in the range of 2.7V to 4.6V. It High Speed (480Mbps) and Full Speed (12Mbps) Signaling was designed to multiplex between three different differential Capability per USB 2.0 on All Ports data sources, allowing the multiplexing of USB 2.0 high speed data signals, UART data signals and digital video through a Digital Video Transmission common headphone connector in Personal Media Players and COM Pins Allow Negative Swings to -2V other portable battery powered devices. All Switches OFF Mode The switch channels have low ON capacitance and high Power OFF Protection bandwidth (1.6GHz) to pass USB high speed signals (480Mbps) and digital video signals with minimal edge and phase distortion COM Pins Overvoltage Tolerant to 5.5V and can swing rail-to-rail to pass UART and full-speed USB Low ON Capacitance 240MHz 2.8pF signals. -3dB Frequency 1.6GHz All channels of the multiplexer can be turned OFF (disabled) by Single Supply Operation (V ) 2.7V to 4.6V DD driving the C0 and C1 logic pins to the low state. Available 12 Ld UTQFN and 12 Ld TQFN Packages The ISL54233 is available in a tiny 12 Ld 2.2mmx1.4mm Compliant with USB 2.0 Short Circuit Requirements Without ultra-thin QFN and 12 Ld 3mmx3mm TQFN package. It operates Additional External Components over a temperature range of -40C to +85C.
