SN74CB3Q6800
10-BIT FET BUS SWITCH WITH PRECHARGED OUTPUTS
2.5-V/3.3-V LOW-VOLTAGE HIGH-BANDWIDTH BUS SWITCH
SCDS142A – OCTOBER 2003 – REVISED MARCH 2005
FEATURES
• High-Bandwidth Data Path (Up To 500 MHz ⁽¹⁾)
• 5-V Tolerant I/Os With Device Powered Up or
Powered Down
• Low and Flat ON-State Resistance (r_on)
Characteristics Over Operating Range
(r_on = 4.5 Ω Typ)
• Rail-to-Rail Switching on Data I/O Ports
– 0- to 5-V Switching With 3.3-V V_CC
– 0- to 3.3-V Switching With 2.5-V V_CC
• B-Port Outputs Are Precharged by Bias
Voltage (BIASV) to Minimize Signal Distortion
During Live Insertion and Hot Plugging
• Supports PCI Hot Plug
• Bidirectional Data Flow With Near-Zero
Propagation Delay
• Low Input/Output Capacitance Minimizes
Loading and Signal Distortion
(C_io(OFF) = 3.5 pF Typ)
(1) For additional information regarding the performance
characteristics of the CB3Q family, refer to the TI application
report, CBT-C, CB3T, and CB3Q Signal-Switch Families,
literature number SCDA008.
• Fast Switching Frequency (f_ON= 20 MHz Max)
• Data and Control Inputs Provide Undershoot
Clamp Diodes
• Low Power Consumption (I_CC = 0.75 mA Typ)
• V_CC Operating 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
• I_off Supports Partial-Power-Down Mode
Operation
• Latch-Up Performance Exceeds 100 mA Per
JESD 78, Class II
• ESD Performance Tested Per JESD 22
