SN74CB3Q3244PWR Datasheet PDF - TI

●description/ordering information

●The SN74CB3Q3244 is a high-bandwidth FET bus switch utilizing a charge pump to elevate the gate voltage of the pass transistor, providing a low and flat ON-state resistance (ron). The low and flat ON-state resistance allows for minimal propagation delay and supports rail-to-rail switching on the data input/output (I/O) ports.

●High-Bandwidth Data Path (Up To 500 MHz†)

●5-V-Tolerant I/Os with Device Powered Up or Powered Down

●Low and Flat ON-State Resistance (ron) Characteristics Over Operating Range(ron = 4 ΩTypical)

●Rail-to-Rail Switching on Data I/O Ports

●  − 0- to 5-V Switching With 3.3-V VCC

●  − 0- to 3.3-V Switching With 2.5-V VCC

●Bidirectional Data Flow, With Near-Zero Propagation Delay

●Low Input/Output Capacitance Minimizes Loading and Signal Distortion(Cio(OFF)= 3.5 pF Typical)

●Fast Switching Frequency (fOE= 20 MHz Max)

●Data and Control Inputs Provide Undershoot Clamp Diodes

●Low Power Consumption(ICC = 0.7 mA Typical)

●VCCOperating Range From 2.3 V to 3.6 V

●Data I/Os Support 0- to 5-V Signaling Levels (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, 5 V)

●Control Inputs Can Be Driven by TTL or 5-V/3.3-V CMOS Outputs

●Ioff Supports Partial-Power-Down Mode Operation

●Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II

●ESD Performance Tested Per JESD 22

●  − 2000-V Human-Body Model (A114-B, Class II)

●  − 1000-V Charged-Device Model (C101)

●Supports Both Digital and Analog

●Applications: Differential Signal Interface, Memory Interleaving, Bus Isolation, Low-Distortion Signal Gating
