SN74CBT3253C DUAL 1-OF-4 FET MULTIPLEXER/DEMULTIPLEXER 5-V BUS SWITCH WITH –2-V UNDERSHOOT PROTECTION
SCDS123B – JULY 2003 – REVISED JANUARY 2007
FEATURES
• SN74CBT3253C Functionally Identical to Industry-Standard ’3253 Function
• Undershoot Protection for Off-Isolation on A and B Ports up to –2 V
• Bidirectional Data Flow, With Near-Zero Propagation Delay
• Low ON-State Resistance (ron) Characteristics (ron = 3 Ω Typical)
• Low Input/Output Capacitance Minimizes Loading and Signal Distortion (Cio(OFF) = 5.5 pF Typical)
• Data and Control Inputs Provide Undershoot Clamp Diodes
• Low Power Consumption (ICC = 3 µA Max) • VCC Operating Range From 4 V to 5.5 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.
