SN74CBTU4411 SCDS192C – APRIL 2005 – REVISED SEPTEMBER 2021 SN74CBTU4411 11-Bit 1-of-4 Multiplexer or Demultiplexer 1.8-V DDR-II Switch With Charge Pump and Precharged Outputs 1 Features Supports SSTL_18 signaling levels Suitable for DDR-II applications D-port outputs are precharged by bias voltage (VBIAS) Internal termination for control inputs High bandwidth (400 MHz minimum) Low and flat ON-state resistance (ron) characteristics, (ron = 17 Ω maximum) Internal 400-Ω pulldown resistors Low differential and rising or falling edge skew Latch-up performance exceeds 100 mA per JESD 78, Class II 2 Applications ATCA solutions Automated external defibrillators Adaptive lighting Blood gas analyzers: portable Bluetooth headsets CT scanners Cameras: surveillance analog Chemical and gas sensors DLP 3D machine vision and optical networking . 3 Description The SN74CBTU4411 device is a high-bandwidth, SSTL_18 compatible FET multiplexer/demultiplexer with low ON-state resistance (ron). The device uses an internal charge pump to elevate the gate voltage of the pass transistor, providing a low and flat ron. The low and flat ron allows for minimal propagation delay and supports rail-to-rail signaling on data input/output (I/O) ports. The device also features very low data I/O capacitance to minimize capacitive loading and signal distortion on the data bus. Matched ron and I/O capacitance among channels results in extremely low differential and rising or ...
