SN74CBT3253C DUAL 1-OF-4 FET MULTIPLEXER/DEMULTIPLEXER

ORDERING INFORMATION The SN74CBT3253C is a high-speed TTL-compatible FET multiplexer/demultiplexer with low ON-state resistance (ron), allowing for minimal propagation delay. Active Undershoot-Protection Circuitry on the A and B ports of the SN74CBT3253C provides protection for undershoot up to –2 V by sensing an undershoot event and ensuring that the switch.

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, 3.3 V, 5.
