SN74CB3Q3384A
10-BIT FET BUS SWITCH
2.5-V/3.3-V LOW-VOLTAGE HIGH-BANDWIDTH BUS SWITCH
SCDS114D – DECEMBER 2002 – REVISED JUNE 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 = 3 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
• Bidirectional Data Flow With Near-Zero
Propagation Delay
• Low Input/Output Capacitance Minimizes
Loading and Signal Distortion
(C_io(OFF) = 4 pF Typ)
• Fast Switching Frequency (f_OE = 20 MHz Max)
(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.
• Data and Control Inputs Provide Undershoot
Clamp Diodes
• Low Power Consumption (I_CC = 1 mA Typ)
• V_CC Operating Range From 2.3 V to 3.6 V
• Data I/Os Support 0- to 5-V Signaling Levels
