SN74CBT16811C

      The SN74CBT16811C is a high-speed TTL-compatible FET bus switch with low ON-state resistance (ron),
allowing for minimal propagation delay.It is organized as is organized as two 12-bit bus switches with separate output-enable (1OE, 2OE) inputs. SN74CBT16811C can be used as two 12-bit bus switches or as one 24-bit bus switch.This device is fully specified for partial-power-down applications using Ioff. The Ioff feature ensures that damaging current will not backflow through the device when it is powered down. The device has isolation during power off.
      Here you can get some SN74CBT16811C information about the features.First is undershoot protection for off-isolation on A and B ports up to -2 V.The second one is that B-Port outputs are precharged by bias voltage (BIASV) to minimize signal distortion during live insertion and hot-plugging.Besides,it supports PCI hot plug.Then is bidirectional data flow and with near-zero propagation delay.Furthermore,data and control inputs provide undershoot clamp diodes.The fifth one is low ON-State resistance (r_on) characteristics (r_on = 3 Typical).The sixth one is low power consumption (I_CC = 3 A Max).The seventh one is V_CC operating range from 4 V to 5.5 V.The last one is that the Ioff supports Partial-Power-Down Mode operation.
      What comes next is about the SN74CBT16811C absolute maximum ratings over operating free-air temperature range.The supply voltage range (V_CC) is from -0.5 V to 7 V.The Bias supply voltage range (BIASV) is from -0.5 V to 7 V.The control input voltage range (V_IN) is from -0.5 V to 7 V.The switch I/O voltage range (V_I/O) is from -0.5 V to 7 V.The control input clamp current (V_IN < 0) (I_IK) is -50 mA.The I/O port clamp current (V_I/O < 0) (I_I/OK) is -50 mA.The ON-state switch current (I_I/O) is ±128 mA.The Continuous current through V_CC or GND terminals is ±100 mA.The storage temperature range (T_stg) is from -65 to 150.
